Influence of Bacillus Spp. Based Bioproducts on Potato Plant Growth and Control of Rhizoctonia Solani 芽孢杆菌生物制品对马铃薯生长的影响及对茄丝核菌的防治
S. Dinu, O. Boiu-Sicuia, F. Constantinescu
Some Bacillus based bioproducts were analyzed for their plant growth promotion and Rhizoctonia solani biocontrol potential in potato plants. The bioproducts were formulated as concentrated aqueous suspension, each containing one of the following plant beneficial bacteria: Bacillus safensis Rd.b2, Bacillus spp. 75.1s and Cp.b4 strains. These were applied on potato seeding material in order to evaluate plant growth promotion effects. The biocontrol efficacy was also evaluated, using Rhizoctonia solani DSM 63002 as plant pathogen, and Prestige 290FS as reference chemical treatment.In the plant growth-promotion experiments, several biologic parameters were biometrically evaluated. Best results regarding plant growth and vigor were obtained using CropMax, a commercial phytostimulatory product. However, the bacterial treatment with Bacillus spp. Cp.b4 and 75.1s showed an improved plant growth compared to the untreated control. An efficacy of 93.75% against Rhizoctonia dumping-off was registered when using the Prestige 290FS chemical control. Mix treatments based on this pesticide, in low dose, combined with Cp.b4 or 75.1s biocontrol strains significantly reduced the pathogenic attack, showing 85 to 87.5% efficacy.The present research demonstrated that the bacterial bioproducts based on Bacillus spp. 75.1s and Cp.b4 strains increase plant growth and are highly effective in controlling Rhizoctonia attack in potato plants.
分析了一些以芽孢杆菌为基础的生物产品对马铃薯植物生长的促进作用和对立枯丝核菌的生物防治潜力。将生物产品配制成浓缩的水悬浮液,每个悬浮液含有以下植物有益细菌之一:安全芽孢杆菌Rd.b2、芽孢杆菌属75.1s和Cp.b4菌株。将其应用于马铃薯播种材料上,以评价其对植物生长的促进作用。以茄丝核菌DSM 63002为病原菌,Prestige 290FS为参考化学处理,对其生物防治效果进行了评价。在植物生长促进实验中,对几个生物学参数进行了生物测定评价。使用商业植物刺激产品CropMax获得了关于植物生长和活力的最佳结果。然而,用芽孢杆菌进行细菌处理。与未处理的对照相比,Cp.b4和75.1s显示出植物生长的改善。当使用Prestige 290FS化学防治剂时,对Rhizoctonia倾倒的有效性为93.75%。基于该农药的低剂量混合处理,与Cp.b4或75.1s生防菌株联合使用,显著降低了致病性攻击,显示出85%至87.5%的疗效。目前的研究表明,以芽孢杆菌属75.1s和Cp.b4菌株为基础的细菌生物产物可以促进植物生长,并对控制马铃薯植物的丝核菌攻击非常有效。

Increased organic acid production and decreased phytate phosphorus by high level of water content of Bacillus subtilis ATCC PTA-6737 fermentation of soybean meal 枯草芽孢杆菌ATCC PTA-6737豆粕高水分发酵提高有机酸产量和降低植酸酶磷
S. Yasar, R. Tosun
In order to enrich soybean meal (SBM) by microbial fermentation, SBM (3 mm particle size) with 78 or 85% moisture content were inoculated with 0.0 or 1x107 CFU/g (colony forming unit) Bacillus subtilis ATCC PTA-6737 and fermented at 37 oC for 0, 24, 48 and 72 h. There was a marked decrease in pH with 85% moisture content, associated at higher organic acid production, compared to increased pH at 24 h with 78% moisture content and a gradual decrease hereafter. Bacterial growth peaked at 48 h with both moisture contents. Fermenting SBM increased crude ash level by 65%, soluble amino acid nitrogen by 2.7 folds and degraded phytic acid by 65-75%. Moreover, there was a high level of organic acid production despite of decreased crude protein by 6-7%, but the effect of high moisture level was more pronounced in all case. In conclusion, fermentation SBM with water content of 85% at 35 oC by B. subtilis provided SBM an appreciable amount of bio-functionalities such reduced phytate content, increased soluble amino acid content and more importantly fortified with organic acids. The fermented SBM can therefore be used an antimicrobial agent due to its high organic acid level in animal nutrition.
为了通过微生物发酵富集豆粕(SBM),用0.0或1x107CFU/g(菌落形成单位)枯草芽孢杆菌ATCC PTA-6737接种含水量为78或85%的SBM(3mm粒径),并在37℃下发酵0、24、48和72小时。含水量为85%时,pH显著降低,这与较高的有机酸产量有关,与在含水量为78%的情况下在24小时时pH增加以及此后逐渐降低相比。细菌生长在两种水分含量下均在48小时达到峰值。发酵SBM使粗灰分增加65%,可溶性氨基酸氮增加2.7倍,降解植酸增加65-75%。此外,尽管粗蛋白质减少了6-7%,但有机酸的产生水平很高,但高水分水平的影响在所有情况下都更明显。总之,枯草芽孢杆菌在35℃下发酵含水量为85%的SBM,为SBM提供了大量的生物功能,如降低了植酸酶含量,增加了可溶性氨基酸含量,更重要的是用有机酸强化。发酵的SBM由于其在动物营养中的高有机酸水平,因此可以用作抗菌剂。

Evaluation of Milk Production at Ţigaie Sheep Reared in Romania Ţigaie罗马尼亚绵羊产奶量评价
C. Pascal, I. Nechifor, M. Florea, S. Dărăban
Biological material subjected to research was represented by females belonging to Ţigaie breed which are in different lactations. Research has been expanded to six consecutive lactations, period in which the followed objectives were represented by: quantity of milk sucked by lambs during lactation, the quantity of milk produced in each lactation period when the flock is located in the milking situation exclusively and the total quantity of milk obtained in each controlled lactation. The work methods used are accepted by experimental practice. During the period of lactation was used the control coefficient method; exclusively for milking period was applied the AT4 method respecting the technical specifications specified by the International Committee for Animal Recording. Also, to eliminate the influence of environment, age, nourishment and maintenance conditions, in each season the period was the same (May-September) and had the same conditions of nourishment, maintenance, sheltering etc. Statistical processing of obtained data at the end of evaluation of milk quantity consumed by lambs show that in first 28 days of suckling, Ţigaie breed sheep furnish around 42% from the total milk quantity consumed by lambs during suckling period. Based on this observation we could say that application of selection at sheep on the basis of lambs’ corporal weight at age of 28 days is more indicated and efficient. In case of appreciation of milk quantity gathered by milking could be observed the fact that face to maximum level reached in first lactation the total estimated quantity was higher with 29.29% in second lactation and after that gradually decrease and record negative values in the last controlled lactation. Effectuation of a rate between milk quantity consumed by lambs and milk quantity obtained after their weaning show the existence of a close rate, with the exception of first lactation when sucked milk quantity was higher with 15.8% face to level of milk production gathered by milking. Statistical processing of information highlighting that between the amounts of milk consumed by lambs in the suckling period, there have been significant differences for P<0.01 and for P>0.05. During the six controlled lactations the maximum milk production was recorded in the second lactation and was of 139.67 kg of milk, superior with 29.29% than level obtained in the first lactation and with 5.29% lower to the total estimated production for the third lactation.
所研究的生物材料以处于不同哺乳期的Ţigaie品种雌性为代表。研究已扩展到连续6次泌乳,期间的以下目标表示为:羔羊在泌乳期间吸乳量,羊群处于完全挤奶状态时每次泌乳期的产奶量以及每次对照泌乳的总产奶量。所采用的工作方法为实验实践所接受。泌乳期采用控制系数法;在遵守国际动物记录委员会规定的技术规范的情况下,仅在挤奶期间采用AT4方法。此外,为了消除环境、年龄、营养和养护条件的影响,每个季节都是相同的时期(5 - 9月),并且具有相同的营养、养护、遮蔽等条件。对羔羊耗乳量评价结束时获得的数据进行统计处理表明,Ţigaie品种绵羊在哺乳前28天的泌乳量约占羔羊在哺乳期间总耗乳量的42%。由此可见,以28日龄羔羊的体重为基础进行选择更为有效。在采奶量增加的情况下,可以观察到在第一次泌乳达到最大水平时,总估计量较高,在第二次泌乳达到29.29%,之后逐渐下降,并在最后一次对照泌乳中出现负值。羔羊消耗的产奶量与断奶后获得的产奶量之间的比率表明存在接近的比率,但第一次泌乳时吸奶量较高,为15.8%,面对挤奶收集的产奶量水平。统计处理的信息突出表明,羔羊在哺乳期消耗的奶量之间,存在显著差异,P0.05。在6次对照泌乳中,第二次泌乳的产奶量最大,为139.67 kg,比第一次泌乳高29.29%,比第三次泌乳的总产奶量低5.29%。

Analysis of the Reproduction Traits and Milk Yield in Cows from Apuseni Mountains Farms 阿普塞尼山区奶牛繁殖特性及产奶量分析
I. Han, O. Bobiș
Milk production in cows is influenced by a series of factors with direct or indirect action upon its body. Farms from three counties in Apuseni Mountains (Alba, Bihor and Hunedoara) were monitorized for milk production and other reproductive attributes. Age of first calving, service period, calving interval and natality were the parameters monitorized in the study to determine the reproduction trains in the area of Apuseni Mountains. Analyzing the obtained data regarding the average production of milk, lactation duration in the studied counties, it is found that: on total lactation, the largest production was obtained in Bihor county with 4815.26 kg (332.6 days), followed by Hunedoara county with 4796.40 kg (325.6 days) and Alba county with 4528.05 kg ( 321.4 days). The obtained results, which reflect the current level of milk production in Apuseni Mountain area, show that the studied cows have a real productive potential, the average of the lactation yields as well as its duration, being at the upper limit of the breed, according also to specialized literature data. Breeding activity was found to be good but can be improved. Due to the great importance of reproduction, the economic and productive performance of dairy farms requires careful attention to its planning and management.
奶牛的产奶量受到一系列对其身体有直接或间接作用的因素的影响。对阿普塞尼山脉三个县的农场(阿尔巴、比霍尔和胡内多阿拉)的产奶量和其他生殖特性进行了监测。以首次产犊年龄、服务期、产犊间隔和出生数为监测参数,确定了阿普塞尼山区的繁殖序列。分析研究县的平均产奶量和泌乳时间数据,发现:总泌乳量最大的县为比荷尔县,产奶量为4815.26 kg (332.6 d),其次为呼尼多阿拉县,产奶量为4796.40 kg (325.6 d),阿尔巴县为4528.05 kg (321.4 d)。所获得的结果反映了Apuseni山区目前的产奶量水平,表明所研究的奶牛具有真正的生产潜力,根据专业文献数据,平均产奶量和持续时间均处于该品种的上限。育种活性良好,但还有待改进。由于繁殖的重要性,奶牛场的经济和生产表现需要仔细注意其规划和管理。

In vitro Multiplication of the Pitcher Plant Sarracenia Purpurea 猪笼草的离体增殖研究
I. Miclea, Rita Bernat
The aim of the current research was to find the best plant growth regulators for the multiplication of Sarracenia purpurea. Murashige and Skoog medium (MS) was prepared with macronutrients and micronutrients at 1/3 strength, full strength vitamins, supplemented with 30 g/l sucrose and 5 g/l phytagel and autoclaved. After cooling 0.5 mgl α-naphthaleneacetic acid (NAA), 5 mgl 6-benzyladenine (BA) or 0.5 mgl NAA + 3 mgl BA were added. Young S. purpurea plants were selected and transferred to media with or without plant growth regulators and cultured for 12 weeks. At the end of this time frame number of roots, root length (cm) and number of shoots were evaluated and differences were analysed by the analysis of variance and interpreted using the Tuckey test. The largest number of roots grew in medium supplemented with 0.5 mgl NAA but the the absence of plant growth regulators increased their length. The best conditions for shoot multiplication were provided by supplementing 1/3MS with 5 mgl BA.
本研究的目的是寻找最佳的植物生长调节剂,以促进紫荆芥的繁殖。在Murashige和Skoog培养基(MS)中加入1/3强度的宏量营养素和微量营养素,全强度维生素,添加30 g/l蔗糖和5 g/l植酸,并进行高压灭菌。冷却后分别加入0.5 mgl α-萘乙酸(NAA)、5 mgl 6-苄基腺嘌呤(BA)或0.5 mgl NAA + 3 mgl BA。选择紫荆幼植株,移栽到有或没有植物生长调节剂的培养基上,培养12周。在此时间段结束时,评估根系数量、根长(cm)和芽数,并通过方差分析和Tuckey检验分析差异。在添加0.5 mgl NAA的培养基中,根的生长数量最多,但不添加植物生长调节剂使根的长度增加。在1/3MS中添加5 mgl BA可提供最佳增殖条件。

The largest number of roots grew in medium supplemented with 0.5 mgl NAA but the the absence of plant growth regulators increased their length. The best conditions for shoot multiplication were provided by supplementing 1/3MS with 5 mgl BA.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Biological activities (antioxidant and antimicrobial activity) of the aqueous extracts and essential oil of Ammoides verticillata (Nounkha) 毛茛(Ammoides verticillata, Nounkha)水提液和精油的生物活性(抗氧化和抗菌活性)
R. M. Said, N. Benmansour
The phytochemical review conducted on the aerial part Ammoides verticillata has revealed the presence of six chemical families: flavonoids, tannins; gallic tannins, anthocyanins and the coumarins, cateichic tannins. The aqueous extract of the Ammoides verticillata could bring back the stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) to the yellow-colored diphenylpicrylhydrazine with an IC50 of 0.020 mg.mL-1. It is gifted with antioxidant activity, however it was less effective than vitamin C (0.001 mL-1). The essential oil of the Ammoides verticillata has presented a strong antimicrobial activity against Gram negatif germs targets of original clinical action: E. coli (ESBL) (37 mm), E. coli (39.5 mm), Klebsiella pneumoniae (36.5 mm) and especially with the yeast: Candida albicans ATCC 10231 (47 mm) and Saccharomyces cerevisie ATCC (42 mm), which are highly sensitive to the oil inhibitory action. However, the oil has presented a low activity against the bacteria P. aeruginosa (12.5 mm).
对轮叶Ammoides verticillata地上部分进行的植物化学审查揭示了六个化学家族的存在:类黄酮、单宁;没食子酸单宁,花青素和香豆素,儿茶酸单宁。轮叶Ammoides verticillata的水提取物可将稳定的2,2-二苯基-1-苦基肼(DPPH)还原为黄色二苯基丙肼,IC50为0.020mg.mL-1。它具有抗氧化活性,但效果不如维生素C(0.001 mL-1)。轮状Ammoides verticillata的精油对革兰氏阴性菌具有很强的抗菌活性,这些革兰氏阴性菌是最初临床作用的靶标:大肠杆菌(ESBL)(37mm)、大肠杆菌(39.5mm)、肺炎克雷伯菌(36.5mm),尤其是与酵母:白色念珠菌ATCC 10231(47mm)和酿酒酵母ATCC(42mm),它们对油的抑制作用高度敏感。然而,该油对铜绿假单胞菌的活性较低(12.5mm)。

MORUS SPP. Material Conservation and Characterization and its Importance for Romanian Sericulture and GCEARS-PSP Development- A Review 桑蚕材料的保存、表征及其对罗马尼亚蚕桑养殖和GCEARS-PSP开发的重要性综述
A. Moise, L. Mǎrghitaş, O. Bobiș, Florina Copaciu, D. Dezmirean
Morus spp. is a perennial and woody plant, belonging to Moraceae family, genus Morus and is essential for sericulture. One of the main aims of Global Centre of Excellence for Advance Research in Sericulture and Promotion of Silk Production (GCEARS-PSP) is to create a reserve of Morus spp., to multiply the vegetal material and to provide it to farmers and also to create an important biotechnological support for further scientifically works. As in Romania the intensive plantations are almost non-existent, one of the main objective of the centre is to create a real base for sericulture revival (the existence of nutritional base for silkworms) and to develop the biotechnological scientific component of the centre.The aims of this review are to create a clear overview of moriculture for sericulture and to reveal the biotechnological potential and pharmacological uses of different mulberry parts. In this review the major findings regarding description of Kokuso 21 variety, mulberry micropropagation and bioactive compounds of different vegetal parts from Mulberry spp. are presented, and represent only the first stage of the GCEARS-PSP activity.
桑树属桑科多年生木本植物,桑树属桑树,是养蚕的重要植物。全球蚕桑先进研究和促进丝绸生产卓越中心(GCEARS-PSP)的主要目标之一是建立桑树保护区,繁殖这种植物材料并将其提供给农民,同时为进一步的科学工作提供重要的生物技术支持。由于在罗马尼亚几乎不存在密集的种植园,该中心的主要目标之一是为蚕桑养殖的复兴创造一个真正的基地(蚕的营养基础的存在),并发展该中心的生物技术科学组成部分。本文综述的目的是为桑蚕养殖提供一个清晰的概述,揭示桑树不同部位的生物技术潜力和药理用途。本文主要介绍了果实21品种的描述、桑树的微繁殖和桑树不同植物部位的生物活性成分等方面的研究成果,并且仅代表了GCEARS-PSP活性的第一阶段。

Dietary Willow Bark Extract for Broilers Reared Under Heat Stress 热应激条件下肉鸡饲粮柳树皮提取物的研究
M. Sărăcilă, T. Panaite, P. A. Vlaicu, C. Tabuc, M. Palade, T. Gavris, R. Criste
A 28-day feeding trial was conducted on 60, Cobb 500 broilers (14 days), assigned to 2 groups (C, E) housed in an experimental hall (32° C, 23 h light regimen). Compared to the conventional diet C, the experimental diet (E) included 1% white willow bark extract (WBE). At 42 days of age, 6 blood samples /group were collected and 6 broilers/ group were slaughtered and caecal content was collected. The dietary WBE didn’t influence broiler performance. The serum concentrations of glycaemia, cholesterol and triglycerides were lower (P <0.05) in E group than in C group. E broilers had the lowest count (P<0.05) of Enterobacteriaceae, E. coli and staphylococci colony forming units in the caecal content. The inclusion of WBE (1%) in the diet of broilers reared at 32° C had an hypocholesterolemiant and hypoglycaemic effect and reduced the pathogenic bacteria in the caecum.
对60只Cobb 500肉鸡(14天)进行了为期28天的饲养试验,分为两组(C、E),分别安置在实验大厅(32°C,23小时光照方案)。与传统饮食C相比,实验饮食(E)包括1%的白柳树皮提取物(WBE)。在42日龄时,采集6份血样/组,屠宰6只肉鸡/组并采集盲肠内容物。日粮WBE不影响肉鸡生产性能。血清血糖、胆固醇和甘油三酯浓度E组低于C组(P<0.05)。E肉鸡盲肠中肠杆菌科、大肠杆菌和葡萄球菌菌落形成单位数最低(P<0.05)。在32°C饲养的肉鸡日粮中加入WBE(1%)具有降胆固醇和降血糖作用,并减少盲肠中的致病菌。
