In this study, the production and characterization of bioethanol from rice and corn straws were investigated.The bioethanol was produced through dilute acid hydrolysis, fermentation and distillation; and the distillateswere purified by dehydration using zeolite 4A. The physicochemical and fuel properties of the bioethanoldistillates including pH, refractive index, specific gravity, flash point, octane rating and calorific or heatingvalue were evaluated. Further characterization of the biofuel was carried out using FTIR and GC-MS. Theresults indicated that octane number, calorific value, and specific gravity of the corn straw bioethanol obtainedwere significantly higher (p<0.05) compared to rice straw bioethanol. Meanwhile, no statistically significantdifference (p˃0.05) was observed in the flash point, refractive index, pH, pour and cloud points of thebioethanol produced from the two lignocellulosic substrates. Furthermore, the results reveal that pH, octanenumber, specific gravity and flash point are within the ASTM standards while refractive index, cloud and pourpoint were slightly outside the ASTM standard. This reveal potential of the feedstock as a source for Bioethanolproduction.
以水稻和玉米秸秆为原料,研究了生物乙醇的制备及其特性。通过稀酸水解、发酵和蒸馏生产生物乙醇;馏分用4A沸石脱水提纯。对生物乙醇馏出物的理化性质和燃料性质进行了评价,包括pH值、折射率、比重、闪点、辛烷值和热值。利用FTIR和GC-MS对生物燃料进行了进一步表征。结果表明,玉米秸秆生物乙醇的辛烷值、热值和比重均显著高于水稻秸秆生物乙醇(p<0.05)。同时,两种木质纤维素基质生产的生物乙醇的闪点、折射率、pH、倒点和浊点均无统计学差异(p < 0.05)。pH值、辛数、比重和闪点均在ASTM标准范围内,折射率、云量和凝结点略超出ASTM标准。这揭示了该原料作为生物乙醇生产来源的潜力。

This study was designed to determine the antibacterial potential of Gum Arabic Tree (Acacia nilotica) pod extracton some pathogenic bacteria which could have health implications. Powdered pods of Acacia nilotica wereextracted with ethanol and distilled water separately. The extracts were tested for antibacterial activities against thetest isolates using Agar Well Diffusion method. The extracts were further subjected to qualitative phytochemicalscreening to detect secondary metabolites present using standard procedures. The minimum inhibitory andminimum bactericidal concentrations of the extracts were also detected using standard procedures. Thephytochemical screening revealed certain metabolites (steroids, saponins, terpenoids, tannins, flavonoids, andalkaloids) in the ethanol and aqueous extracts, except for steroids, which were present only in ethanol extract. Theresult of the sensitivity test showed that ethanol pod extract produced the highest and least zone of inhibition againstPseudomonas aeruginosa (22 mm) and S. typhi (15 mm) respectively at 50mg/ml while the aqueous extract of thepod exhibited activity against S. typhi (20 mm) and E. coli (12 mm) at 50 mg/ml. This showed that the A. niloticapod extracts could serve as potential antibacterial agents against pathogenic bacteria.

There is a growing demand to establish reliable method for the detection of cyanobacterial toxins in order to bewell informed on the prevalence of cyanotoxins in our environments. This study employed the underivatizedmethod of analysis to detect the production of BMAA by the axenic cultures of cyanobacterial strains SynechocystisNPLB 2 and Nostoc MAC PCC 8009 using liquid chromatography-electrospray ionization - ion trap massspectrometry (LC/ESI-ITMS). Cyanobacterial cultures were grown in the laboratory for 12 weeks after whichBMAA was extracted using methanol and analysed by LC/ESI-ITMS. Based on retention time, mass-to-chargeratio, and ratio of the product ions, the underivatized method of analysis employed in this study showed that bothSynechocystis NPLB 2 and Nostoc MAC PCC 8009 strains produced BMAA. The results of this study suggests thatthe LC/ESI-ITMS is a promising method for the analysis of BMAA in cyanobacterial matrices.

The study examined the impact of Purdue Improved Cowpea Storage (PICS) Bag on the Profitability of CowpeaStorage in Kontagora Local Government Area of Niger State, Nigeria. Data were collected using a structuredquestionnaire. Descriptive statistics, multiple regression, independent t-test and farm budgeting models wereemployed for data analysis. Results of the descriptive analysis revealed that cowpea storage in the study areawas gender bias given that majority (94.2%) of the respondents were men. About (98.3%) had one form offormal education or the other, while (76.7%) had above 15 years farming experience. Results from the CobbDouglas regression model indicated that among socio-economic factors such as age, household size and yearsof experience, only age have a significant positive impact on the profitability of cowpea storage using PICSbag (p<0.097). The profitability analysis puts the average net revenue for chemical and PICS bags users at₦48,210 and ₦82,730 per hectare, respectively. The difference in profit was statistically significant (P< 0.00),implying that PICS bags usage was more profitable and had an impact on cowpea storage in the study area.Against this background, it was recommended that Niger State Government, through the Extension Componentof the State Agricultural Mechanization and Development Authority (NAMDA) promote efficient use ofimproved storage technology (PICS bag) amongst cowpea farmers in the study area with the view to ensuringprofitable and sustainable cowpea production.
本研究考察了普渡改良豇豆储存袋(PICS)对尼日利亚尼日尔州Kontagora地方政府地区豇豆储存盈利能力的影响。使用结构化问卷收集数据。采用描述性统计、多元回归、独立t检验和农场预算模型进行数据分析。描述性分析的结果显示,研究区域的豇豆储存存在性别偏见,因为大多数(94.2%)的受访者是男性。约(98.3%)接受过一种或另一种形式的正规教育,而(76.7%)有15年以上的农业经验。CobbDouglas回归模型结果表明,在年龄、家庭规模和经验年限等社会经济因素中,只有年龄对PICSbag储存豇豆的盈利能力有显著的正影响(p<0.097)。盈利能力分析显示,化学品和PICS袋用户的平均净收入分别为每公顷48,210奈拉和82,730奈拉。利润差异有统计学意义(P< 0.00),表明PICS袋的使用更有利可图,并对研究区域的豇豆储存产生影响。在此背景下,建议尼日尔州政府通过国家农业机械化和发展局(NAMDA)的推广部分,在研究地区的豇豆农民中推广有效使用改良储存技术(PICS袋),以确保豇豆生产的盈利和可持续。

Extended-Spectrum Beta-Lactamase (ESBL) producing bacteria are of great concern to healthcare because of theirresistance to β-lactam antibiotics. This study aims to screen Gram-negative bacteria recovered from fruit andvegetable salads for ESBL production. The bacteria in thirty samples of fruit and vegetable salads purchased fromfood vendors were isolated and identified with standard microbiological methods. The Gram-negative bacteriarecovered were screened for ESBL production by the double disk synergy test (DDST) and brilliance ESBL agar(BEA). The total coliform counts in the fruit and vegetable salads were in the ranges 2.3 - 19.1 x 104 cfu/g and 2.8- 19.4 x 104 cfu/g respectively. Ninety-eight (98) Gram-negative bacteria were recovered from the salad samples.They were Escherichia coli (34.7%), Citrobacter freundii (21.4%), Enterobacter cloacae (10.2%), Enterobacteraerogenes (9.2%), Pseudomonas aeruginosa (9.2%). Klebsiella oxytoca (8.2%), Klebsiella pneumoniae (4.1%) andProteus mirabilis (3.1%). For ESBL production using DDST, 43. 9% (43) of the isolates were positive for the test.On the brilliance agar, 68.4% (67) showed the expected colour change as outlined by the manufacturer. However,five strains of K. oxytoca showed blue growth while sixteen of C. freundii had brown growth. ESBL-producing E.coli strains that were not detected with DDST grew on BEA. This finding showed that ESBL-producing bacteriaare present in fruit and vegetable salads retail in Ago-Iwoye, hence, there is need to take the necessary precautionsduring the preparation and storage of these food products to prevent contamination by these pathogens andsubsequent production of ESBL.
广谱β-内酰胺酶(ESBL)产生菌对β-内酰胺类抗生素具有耐药性,引起了广泛关注。本研究旨在筛选从水果和蔬菜沙拉中回收的革兰氏阴性菌用于ESBL生产。用标准微生物学方法对从食品供应商处购买的30份果蔬沙拉样品中的细菌进行了分离和鉴定。通过双盘协同试验(DDST)和光亮度ESBL琼脂(BEA)筛选复盖的革兰氏阴性菌是否产生ESBL。水果沙拉和蔬菜沙拉中大肠菌群总数分别为2.3 ~ 19.1 × 104 cfu/g和2.8 ~ 19.4 × 104 cfu/g。从沙拉样品中检出98个革兰氏阴性菌。分别为大肠杆菌(34.7%)、弗氏柠檬酸杆菌(21.4%)、阴沟肠杆菌(10.2%)、产气肠杆菌(9.2%)、铜绿假单胞菌(9.2%)。产氧克雷伯菌(8.2%)、肺炎克雷伯菌(4.1%)和奇异变形杆菌(3.1%)。对于使用DDST的ESBL生产,43。9%(43株)的分离株检测呈阳性。在光辉琼脂上,68.4%(67)显示出制造商概述的预期颜色变化。然而,5株芽孢杆菌呈蓝色生长,16株弗氏胞杆菌呈棕色生长。DDST检测不到的产esbl大肠杆菌菌株在BEA上生长。这一发现表明,在Ago-Iwoye零售的水果和蔬菜沙拉中存在产生ESBL的细菌,因此,在这些食品的制备和储存过程中需要采取必要的预防措施,以防止这些病原体污染和随后的ESBL生产。

The total coliform counts in the fruit and vegetable salads were in the ranges 2.3 - 19.1 x 104 cfu/g and 2.8- 19.4 x 104 cfu/g respectively. Ninety-eight (98) Gram-negative bacteria were recovered from the salad samples.They were Escherichia coli (34.7%), Citrobacter freundii (21.4%), Enterobacter cloacae (10.2%), Enterobacteraerogenes (9.2%), Pseudomonas aeruginosa (9.2%). Klebsiella oxytoca (8.2%), Klebsiella pneumoniae (4.1%) andProteus mirabilis (3.1%). For ESBL production using DDST, 43. 9% (43) of the isolates were positive for the test.On the brilliance agar, 68.4% (67) showed the expected colour change as outlined by the manufacturer. However,five strains of K. oxytoca showed blue growth while sixteen of C. freundii had brown growth. ESBL-producing E.coli strains that were not detected with DDST grew on BEA. This finding showed that ESBL-producing bacteriaare present in fruit and vegetable salads retail in Ago-Iwoye, hence, there is need to take the necessary precautionsduring the preparation and storage of these food products to prevent contamination by these pathogens andsubsequent production of ESBL.","PeriodicalId":158544,"journal":{"name":"Equity Journal of Science and Technology","volume":"71 9-10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132693207","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}

The aim of this research was to determine the impact of biofilms on water distribution system of FederalUniversity Birnin Kebbi. Samples were collected from different water distribution pipelines in the University.Total heterotrophic count was carried out to determine the microbial load and Most Probable Method (MPN)was used to detect the presence of fecal coliforms in the water. Total heterotrophic bacterial count rangedbetween 1.6×103 to 3.9×103 cfu/ml. Escherichia Coli showed the highest frequency (25%) of occurrence, whilethe least frequency of occurrence (5%) was recorded for Klebsiella spp and Enterobacter spp respectively. Theisolates identified were Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella spp,Enterobacteria Spp, Salmonella Spp and Bacillus Spp. Presence of these isolates is of significant concern andmay cause some water borne diseases like diarrhea, dysentery etc. It is therefore recommended that water boardtreatment plant should use disinfectant chemicals like chlorine and perform regular proactive preventivemaintenance, microbial monitoring and infrastructure replacement and repair so as to reduce the occurrence ofbiofilms in the Water Distribution system.
本研究的目的是确定生物膜对联邦大学Birnin Kebbi配水系统的影响。从大学内不同的配水管道采集样本。采用总异养计数法测定水体微生物负荷,采用最可能法(MPN)检测水体中粪便大肠菌群的存在。总异养细菌计数在1.6×103至3.9×103 cfu/ml之间。大肠杆菌的发生率最高(25%),克雷伯氏菌和肠杆菌的发生率最低(5%)。鉴定出的分离株为金黄色葡萄球菌、大肠杆菌、铜绿假单胞菌、克雷伯氏菌、肠杆菌、沙门氏菌和芽孢杆菌。这些分离株的存在值得关注,可能导致腹泻、痢疾等水媒疾病。建议水板处理厂使用氯等消毒剂,定期进行主动预防性维护、微生物监测和基础设施更换维修,以减少配水系统中生物膜的发生。

The study assessed the factors influencing extension workers effective use of Knowledge Management (KM) inSokoto State, Nigeria. Purposive sampling procedure was used to sample respondents from the study area andExtension Workers were selected from Sokoto Agricultural Development Project (SADP). Socio-economiccharacteristics were using structured questionnaire and a total of 188 respondents were sampled and data collectedanalysed using descriptive statistics and logit model as tools of analysis. The result of the study showed that 74.4% ofthe extension workers were male and majority (79.8%) were married. More so, 35% of the extension workers arewithin the age range of 31 – 40 years with household average size of 5-10 children. Majority (79%) of the extensionworkers had tertiary education. (35%) had experience ranging from 21-25 years on extension service delivery. About41% of respondents used motor cycle as a mean of transportation. Result of logit model shows that marital status,level of education, service experience, cosmopolitness and means of transportation had positive and significantrelationship with effectiveness of KM whereas household size and rank of extension workers had significant andnegative relationship with KM. It is therefore recommended that KM be encouraged and disseminated through topmanagement approach in SADP. This will avail quality and better extension service delivery by extension agencybecause the vast knowledge and experience garnered on effective extension service delivery by top managementofficer will be shared and passed on to junior officers. This will go in line with strengthening and improving thecapacity building of extension workers.
该研究评估了影响尼日利亚索科托州推广工作者有效利用知识管理的因素。采用有目的抽样程序对研究区域的受访者进行抽样,并从索科托农业发展项目(SADP)中选择推广工作者。采用结构化问卷法对188名调查对象的社会经济特征进行抽样调查,采用描述性统计和logit模型进行分析。研究结果表明,74.4%的推广人员为男性,79.8%的推广人员已婚。此外,35%的推广工作者年龄在31 - 40岁之间,家庭平均规模为5-10个孩子。大多数(79%)的延伸工作者受过高等教育。(35%)有21-25年的推广服务提供经验。约41%的受访者以电单车作为交通工具。logit模型结果显示,婚姻状况、文化程度、服务经验、国际化程度和交通工具对知识管理效能有显著的正向影响,而家庭规模和推广人员职级对知识管理效能有显著的负向影响。因此,建议通过SADP的高层管理方法鼓励和传播知识。这将有利于推广机构提供高质量和更好的推广服务,因为高级管理人员在有效提供推广服务方面积累的丰富知识和经验将被分享并传递给下级官员。这与加强和改善推广人员的能力建设是一致的。
