This study aims to examine the effect of honey from Apis cerana bee colonies on nutritional status in children aged two to five years old in the working area of ​​Mok Community Health Center, Manggarai Regency, East Nusa Tenggara - Indonesia. The study was conducted in May - June 2018, with quasi-experiment design with pre and post test in one group. The sample in this study amounted to 35 children under five years old, with malnutritional status. Nutritional status is determined by the weight-for-age. The used honey was honey from the A. cerana bee colonies harvested in Manggarai Regency. Honey was consumed by children as much as 5 mL, twice a day, morning and evening, for 8 weeks. Nutritional status measurements were taken at 0 weeks, 4 weeks and 8 weeks before and after honey consumed regularly. Post-Hoc data analysis using the Wilcoxon Signed Rank Test. The results showed a significant increase in children's nutritional status at week 4 and week 8. The percentage of children with malnutritional status after being given honey A. cerana regularly for 4 weeks fell to 57% and good nutrition increased to 43%. Meanwhile, after 8 weeks of honey, the malnutritional status has decreased to 31%, and vice versa 69% of children have increased their nutritional status to good nutrition. The results of a comparative test of increasing nutritional status between 4 and 8 weeks showed that there was a significant difference between improving the nutritional status of children under five years old who consumed honey for 4 weeks and for 8 weeks. The research  shows the length of time consumed  A. cerana honey regularly in children aged two to five years old, will have a positive effect to the nutritional status from poor to good nutritional status.
本研究旨在研究中国蜜蜂蜂群蜂蜜对印度尼西亚东努沙登加拉Manggarai Regency Mok社区卫生中心工作区域2至5岁儿童营养状况的影响。本研究于2018年5 - 6月进行,采用准实验设计,前后测试为一组。本研究的样本为35名5岁以下营养不良的儿童。营养状况由年龄体重决定。所使用的蜂蜜是从Manggarai摄制区收获的A. cerana蜂群中提取的蜂蜜。儿童食用蜂蜜最多5毫升,每天两次,早晚,持续8周。定期食用蜂蜜前后分别于0周、4周和8周进行营养状况测量。事后数据分析采用Wilcoxon符号秩检验。结果显示,在第4周和第8周,儿童的营养状况显著提高。定期给予蜂蜜蜜蜂4周后营养不良的儿童比例下降到57%,营养良好的儿童比例上升到43%。同时,经过8周的蜂蜜喂养,营养不良的儿童比例下降到31%,反之,69%的儿童营养状况改善到营养良好。一项在4周和8周之间增加营养状况的比较试验结果表明,5岁以下儿童在4周和8周内食用蜂蜜对营养状况的改善有显著差异。研究表明,在2 - 5岁的儿童中,定期食用蜜蜂蜂蜜的时间长度,将对营养状况由差到好产生积极影响。

In poultry breeding program the success of artificial insemination (AI) is highly influenced by  the quality of semen. The aim of the present research was to evaluate the variations in semen characteristics of three phenotypes of chicken of the same specie raised in Akko, Nigeria. A total of 9 cocks from threedifferent phenotypes; Red feathered (n = 3), White feathered (n = 3) and Black feathered (n =3). The semen was evaluated for macroscopic (i.e. semen volume and colour) and microscopic (i.e. sperm concentration, motility and morphology) criteria after being collected by abdominal massage method. There were phenotypes variation (P > 0.05)effects on semen motility, number of live/dead sperm and sperm abnormalities. No differences(P>0.05) were observed on volume, colour, concentration, mass motility and pH of semen. The observed sperm progressive motility was ranged from 90.5 ±1.21% to 95.09±0.82%. The White feathered strain had the highest sperm progressive motility (P<0.05)and highest value for live and normal sperm (93.5±0.63% and 87.90±0.25%), while the black feathered had the least and (92.4±0.73% and 85.5±0.50%) respectively. The Red feathered strain had the highest value for both dead and sperm head defect (9.2±0.33%and 7.0±0.52%). Whilst, the Black feathered strain scored the highest percentage of both sperm tail and neck defects with values ranged from 11.4±0.43%to 14.2±1.08% and 19.4±0.53% to 23.6±0.69%, respectively. This study suggests that there are large variations present in semen characteristics of different phenotypes of cocks; White feathered strain is likely have better semen characteristics compared to Red and Black feathered strains. Therefore, White feathered strain can potentially be used in artificial insemination (AI) for chicken production and improvement.
在家禽育种中,人工授精的成功与否在很大程度上取决于精液的质量。本研究的目的是评估在尼日利亚阿科饲养的同一种鸡的三种表型的精液特征的变化。共有3种不同表型的9只公鸡;红色羽毛(n =3),白色羽毛(n =3)和黑色羽毛(n =3)。采用腹部按摩法采集的精液进行宏观(即精液体积和颜色)和微观(即精子浓度、活力和形态)的评价。精子活力、活死精子数和精子异常均存在表型差异(P > 0.05)。精液的体积、颜色、浓度、质量运动性和pH值差异均无统计学意义(P>0.05)。精子进行性活动力为90.5±1.21% ~ 95.09±0.82%。白羽品系精子进动率最高(P<0.05),活精子和正常精子进动率最高(93.5±0.63%和87.90±0.25%),黑羽品系精子进动率最低(92.4±0.73%和85.5±0.50%)。红羽品系死亡和精头缺陷率最高,分别为9.2±0.33%和7.0±0.52%。黑羽品系的精子尾部和颈部缺陷率最高,分别为11.4±0.43% ~ 14.2±1.08%和19.4±0.53% ~ 23.6±0.69%。本研究表明,不同表型公鸡的精液特征存在较大差异;与红羽和黑羽菌株相比,白羽菌株可能具有更好的精液特征。因此,白羽菌株在鸡的人工授精生产和改良中具有潜在的应用前景。

Protease is an important industrial enzyme and salt tolerant protease in which has desirable properties that could enhance its uses not only in industries, but also in agriculture and environmental. Marine organisms usually harbour halophilic microorganisms which produce salt tolerant protease.  In this study, salt tolerant protease producing bacteria from marine sponge were isolated and screened on skim milk marine agar supplemented with different NaCl concentrations (1.5 % w/v). Out of 11 isolates, 8 isolates (S1-1, S1-2, S1-3, S2-1, S2-3, S2-4, S2-5 and S2-6) showed clearing zones with ability to digest casein on the skim milk agar. Morphologically, these strains are gram negative bacilli which grow in yellow colonies and were found to be catalase-positive but oxidase-negative. They are also non-lactose fermenter that produce gelatinase but not α-amylase. The ribosomal 16S rRNA sequencing was used to identify each isolate (Acc. number of S1-1 for MT645770, S1-2 for MT645 771, S1-3 for MT645 772, S2-1 MT645 773, S2-3 MT645 774, S2-4 MT645 775, S2-5 MT645 776 and S2-6 MT645 7767). The 16S rRNA sequences showed that these isolates were highly similar to Stenotrophomonas maltophilia (S2-6, 99.87%) and to a related strain Pseudomonas hibiscicola (S1-1, S1-2, S1-3, S2-1, S2-3, S2-4, S2-5   (97.16-99.9 %). Further proteolytic studies were carried out using skim milk agar with 1.0 %, 2.0 %, 3.0 % and 4.o % (w/v) of NaCl concentrations. All isolates were able to hydrolyze casein which produced clear zones surrounding each colony at 1.0 % and 2.0 % (w/v) salt. However, only isolate S1-5 and S2-6 showed proteolytic activities at 3.0 % (w/v) salt but none of them at 4.0 % (w/v). The ability of these isolates to produce protease which active at higher salt may indicate their potential to be the sources for enzyme with useful properties.
蛋白酶是一种重要的工业酶和耐盐蛋白酶,它具有良好的性能,不仅在工业上,而且在农业和环境方面都有广泛的应用。海洋生物通常孕育着能产生耐盐蛋白酶的嗜盐微生物。本研究从海绵中分离出耐盐蛋白酶产菌,并在添加不同NaCl浓度(1.5% w/v)的脱脂乳海洋琼脂上进行筛选。11株分离菌中,有8株分离菌(S1-1、S1-2、S1-3、S2-1、S2-3、S2-4、S2-5和S2-6)在脱脂乳琼脂上表现出能够消化酪蛋白的清除区。形态学上,这些菌株为革兰氏阴性杆菌,生长在黄色菌落中,过氧化氢酶阳性,氧化酶阴性。它们也是产生明胶酶而不产生α-淀粉酶的非乳糖发酵剂。采用核糖体16S rRNA测序对每个分离株进行鉴定(Acc;S1-1适用于MT645770、S1-2适用于MT645 771、S1-3适用于MT645 772、S2-1适用于MT645 773、S2-3适用于MT645 774、S2-4适用于MT645 775、S2-5适用于MT645 776和S2-6适用于MT645 7767)。16S rRNA序列显示,这些分离株与嗜麦芽窄养单胞菌(S2-6, 99.87%)和与之相关的木蓟假单胞菌(S1-1, S1-2, S1-3, S2-1, S2-3, S2-4, S2-5)高度相似(97.16- 99.9%)。分别以1.0%、2.0%、3.0%和4.0%的脱脂乳琼脂进行蛋白水解研究。0 % (w/v) NaCl浓度。所有菌株都能水解酪蛋白,在1.0%和2.0% (w/v)盐浓度下,酪蛋白在每个菌落周围产生清晰的区域。在3.0% (w/v)盐条件下,只有S1-5和S2-6具有蛋白水解活性,而在4.0% (w/v)盐条件下均无蛋白水解活性。这些分离物产生在高盐条件下具有活性的蛋白酶的能力可能表明它们有可能成为具有有用性质的酶的来源。

Catunaregam tomentosa (Blume ex DC) Tirveng is commonly known as Khet in Thailand and Bisa Ular or Badang in Malaysia. The tree is widely distributed in the north-east region of Thailand while in Malaysia the tree usually grows in the open waterfront area at Terengganu. This plant belongs to the Rubiaceae family, and the genus catunaregam has interesting pharmacological activities such as anti-inflammatory, antispasmodic, antidysenteric, antifertility and immunomodulatory. In this study, the leaves were extracted using dichloromethane, ethyl acetate and ethanol. Total phenolic was determined by Folin-Ciocalteau method while total flavonoid was determined by the aluminium chloride calorimetric method. Meanwhile, its antioxidant activity was evaluated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The ethanolic extract was found to have the highest percentages of phenolic and flavonoid content. Interestingly, ethanolic extract also demonstrated strong DPPH scavenging activity with IC50 at 20.07 ± 0.51µg/mL.

The main purpose of this research was to find the best growth curve for bacterial growth and the optimum temperature for the production of phytase from different potential phytase producing bacterial strains. A total of four strains used were originally isolated from hot springs in Malaysia, which were in Labis, Johor (L3), Dusun Tua, Selangor (RT), Ulu Legong, Kedah (A) and Ranau, Sabah (B9). Nutrient Agar (NA) and modified Phytase Screening Medium (PSM) liquid media were used for the culture enrichment while optimisation was carried out through batch culture method using a shake-flask scale. Strains growth and enzyme activity were quantitatively measured at different temperatures at (30°C and 37°C) values. Enzyme activity was determined according to the reaction of the phytase with its substrate (sodium phytate) and expressed in units of phytase activity (U/ mL). As for the overall, strain L3 (from Labis, Johor) exhibit promising rate of Pi released in the media at 30°C and 37°C, with optimum phytase activity values of 0.2047 U/mL and 0.2195 U/mL, respectively. The pH of the cultures was also measured, where it shows that strains grown in cultures at 37°C produced a higher phytase activity and resulting a lower reading of pH compared when grown at 30°C. All around, L3 strains has the lowest value of pH when cultured at 30°C and 37°C, with the pH value of 3.62 and 2.37, respectively.  From the result obtained, the lower pH indicates the process of phytic acid degradation take place by the phytase in producing inorganic phosphate (Pi) due to the accumulation of organic acid. Since these bacterial strains were originally taken from Hot Springs, further analysis of temperature optimization using 55°C and even 60°C should be carried out. In the future, biochemical research and molecular identification may also be carried out to identify molecular identity in the strains.
本研究的主要目的是寻找不同产植酸酶潜力菌株的最佳生长曲线和产植酸酶的最佳温度。所使用的四种菌株最初是从马来西亚的温泉中分离出来的,分别是柔佛州拉比斯(L3)、雪兰莪州Dusun Tua (RT)、吉打州乌鲁勒贡(A)和沙巴拉瑙(B9)。采用营养琼脂(NA)和改良植酸酶筛选培养基(PSM)液体培养基进行培养富集,并采用摇瓶规模分批培养法进行优化。在不同温度下(30°C和37°C)定量测定菌株生长和酶活性。根据植酸酶与其底物(植酸钠)的反应测定酶活性,以植酸酶活性单位(U/ mL)表示。总体而言,菌株L3(来自柔佛Labis, Johor)在30°C和37°C的培养基中表现出良好的Pi释放率,最佳植酸酶活性值分别为0.2047 U/mL和0.2195 U/mL。还测量了培养物的pH值,结果表明,与在30°C培养的菌株相比,在37°C培养的菌株产生更高的植酸酶活性,pH值读数较低。从各方面来看,L3菌株在30℃和37℃培养时pH值最低,分别为3.62和2.37。从得到的结果来看,较低的pH值表明由于有机酸的积累,植酸酶在产生无机磷酸盐(Pi)时发生了植酸降解过程。由于这些菌株最初是从温泉中提取的,因此需要在55°C甚至60°C下进行进一步的温度优化分析。今后还可开展生化研究和分子鉴定,对菌株进行分子鉴定。

The pH of the cultures was also measured, where it shows that strains grown in cultures at 37°C produced a higher phytase activity and resulting a lower reading of pH compared when grown at 30°C. All around, L3 strains has the lowest value of pH when cultured at 30°C and 37°C, with the pH value of 3.62 and 2.37, respectively.  From the result obtained, the lower pH indicates the process of phytic acid degradation take place by the phytase in producing inorganic phosphate (Pi) due to the accumulation of organic acid. Since these bacterial strains were originally taken from Hot Springs, further analysis of temperature optimization using 55°C and even 60°C should be carried out. In the future, biochemical research and molecular identification may also be carried out to identify molecular identity in the strains.","PeriodicalId":14995,"journal":{"name":"Journal Of Agrobiotechnology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89044619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A study was conducted to attract insects using different colours of sticky trap in pumpkin (Cucurbita moschata) field. Sticky trap was chosen as it is one of a method to estimate the insect population density in field as it requires a low cost and less skilled labour. Four different colours of sticky traps (i.e. red, white, blue and yellow) were used to determine the insect population abundance at the pumpkin field. All the traps were installed at the height of 100 cm at a random of 1 ha of pumpkin plot with five replicates for each colour and the insect samples were collected weekly for three months (October-December 2019). Overall, a total of 13,052 insects were collected throughout 11 weeks of sampling. The results showed that the percentage of insect population abundance recorded the highest was on week eight (15.01%) whilst the least abundance of insects trapped was on week one (2.28%). The most attractive colour to attract insects was significantly the yellow colour (44.34%) followed by blue (20.12%) and white (19.15%) whilst the lowest insect trapped was on red colour (16.40%). A total of nine insect orders recorded were; Diptera, Hemiptera, Coleoptera, Hymenoptera, Lepidoptera, Orthoptera, Blattodea, Isoptera and others. Diptera was the most abundant of insect’s order trapped in the yellow trap with 3427 individuals and followed by Hemiptera order (1022 individuals). Whilst the Isoptera order was the least number of insects caught on a red colour trap with only one individual. In conclusion, our findings showed that the yellow sticky trap colour is the most attractive to attract insects of C. moschata compared to other colours. Therefore, this study could provide essential knowledge that may be useful for the future ecological survey of insects of C. moschata.
采用不同颜色的粘捕器在南瓜田进行了诱虫试验。选择粘捕法是一种估算田间昆虫密度的方法,成本低,技术含量低。采用红、白、蓝、黄四种不同颜色的粘捕器测定南瓜田昆虫数量。所有诱捕器在1公顷南瓜地随机设置,高度为100 cm,每种颜色5个重复,每周收集昆虫样本,为期3个月(2019年10 - 12月)。在11周的采样中,总共收集了13052只昆虫。结果表明,第8周捕获的昆虫种群丰度最高(15.01%),第1周捕获的昆虫丰度最低(2.28%)。捕虫效果最好的颜色是黄色(44.34%),其次是蓝色(20.12%)和白色(19.15%),捕虫效果最低的颜色是红色(16.40%)。记录的昆虫目共有9目:双翅目、半翅目、鞘翅目、膜翅目、鳞翅目、直翅目、鳞翅目、等翅目等。黄诱蝇器捕获的昆虫以双翅目最多,达3427只,半翅目次之,达1022只。而等翅目是被红色诱捕器捕获的昆虫数量最少的,只有一个个体。综上所述,与其他颜色相比,黄色粘捕器颜色对莫沙塔的引诱性最强。因此,本研究可为今后柽柳昆虫的生态调查提供必要的知识。

The bitter taste of Momordica charantia due to its high level of calcium content limits people from consuming it, although it has enough various beneficial nutrients. Parental line evaluation is prerequisite for any desired improvement activities through breeding.   In this regard M. charantia parental lines were evaluated based on bitterness (high Ca content) and morpho-nutritional attributes to augment additional value and opportunity to be commercialized. Field and laboratory experiments were carried out for three open-pollinated M. charantia varieties to screen low bitterness parental lines based on low calcium contents and other morpho-nutritional qualities, targeting to generalize this important vegetable crops for all types of consumers from child to older age. From the overall results of the study, Variety 2 showed better quality for numbers of fruits per plant, fruit weight (g), moisture content (%), chlorophyll content (mmol/m²), stomatal conductance (mmol/m²s) and nutrients content such as calcium (Ca), nitrogen (N), magnesium (Mg) and iron (Fe). Variety 3 had good quality for morphological parameters like plant height (cm), numbers of leaves per plant, leaf area (cm²), fruit length (cm), phosphorus (P), potassium (K), aluminium (Al) and copper (Cu). Variety 1 had the highest values only for number of branches per plant and amount of sodium (Na) content. After that, Variety 2 was identified for having lowest calcium (Ca) contents compared to the other two varieties. Thus, Variety 2 was selected as better parents to hold good promise for hybridization based breeding programs for varietal improvement in obtaining low bitterness bitter gourd but rich in other nutrient contents.
苦瓜含有多种有益的营养成分,但由于钙含量高,苦瓜的苦味限制了人们食用它。亲本系评价是通过育种进行任何改良活动的先决条件。在这方面,根据苦味(高钙含量)和形态营养属性来评估沙兰氏母系,以增加附加价值和商业化机会。通过田间和室内试验,筛选了3个开放授粉的夏蓝草品种,根据其低钙含量和其他形态营养品质来筛选低苦味亲本,旨在推广这一重要的蔬菜作物,使其适用于从儿童到老年人的所有类型的消费者。从研究的总体结果来看,品种2在单株果数、果重(g)、水分含量(%)、叶绿素含量(mmol/m²)、气孔导度(mmol/m²s)和钙(Ca)、氮(N)、镁(Mg)和铁(Fe)等营养成分含量方面表现出较好的品质。品种3在株高(cm)、单株叶数、叶面积(cm²)、果长(cm)、磷(P)、钾(K)、铝(Al)和铜(Cu)等形态参数上均具有较好的品质。品种1仅单株分枝数和钠含量最高。之后,品种2与其他两个品种相比,被鉴定为钙含量最低。因此,选择品种2作为较好的亲本,在以杂交育种为基础的品种改良计划中具有良好的前景,可以获得低苦味但其他营养成分丰富的苦瓜。
