The objectives was to collect ethnobotany information of the edibles, analyse the level of nutrients and use the obtained information to create awareness in the community on how to use these edibles to improve its economy and health of the citizens. Questioners were used to obtain ethnobotanical information. Opportunistic collection of the edibles was done in March during the rainy season. One hundred edibles were collected for analysis and 80 respondents were interviewed. Data analysis was accomplished using one way ANOVA in the SPSS software (Version 14). Indigenous names and medicinal use of the edibles were reported. Utility and awareness of the community to the edibles was observed to be higher although not statistically significant. Three vegetable species were observed to be more nutritive and statistically significant than others in terms of Fe2+ and ß-carotene while all mushrooms collected were observed to be rich in Fe2+ and PO3-4. Three fruit species, four vegetables species, and two mushrooms families were observed to be preferably eaten in the community. Vitex mombasae and Agaricaceae were the dominating population in the study area. However, the differences in the nutrient levels in the fruits and mushrooms were statistically not significant. Communities were gathered to receive feedback and create awareness on the importance and use of the edibles. The government is encouraged to be involved in the dissemination of this information to bolster the economy and improve the health of her people.","PeriodicalId":39601,"journal":{"name":"Annals of Agri Bio Research","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79179095","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}

Groundnut and sheanut shell biochars were produced at pyrolysis temperatures of 350 ± 5 °C and 700 ± 5 °C using muffle furnace. The chemical characteristics of the biochars were analysed, potential contamination and ecological risk were determined based on the metal enrichment index and potential ecological risk index (PERI). pH values of the biochars ranged from 9.42 to 10.23 and 662.33 to 3206.67 μS/cm for electrical conductivity. The total compositions of carbon and nitrogen for GB350, GB700, SB350 and SB700 ranged from 58.13% to 70.23% and 0.45% to 1.37%, respectively. The minerals composition of GB350, GB700, SB350 and SB700 ranged from 12944.92 to 20873.30 mg/kg for potassium, 192.24 to 410.72 mg/kg for sodium, 3567.98 to 13451.83 mg/kg for calcium and 1150.33 to 3414.34 mg/kg for magnesium. The pH of the biochars is found to be alkaline which upsurge with increasing pyrolysis temperature. Concentrations of nutrients such as calcium, potassium, magnesium and phosphorus diverse in groundnut shells feedstocks due to the pyrolysis conditions. The groundnut and sheanut shell biochars can increase essential nutrients such as nitrogen, phosphorus, and potassium in soil, which are conducive to growth of plant. The availability of phosphorus in the biochars make it phosphorus-rich and can be used as slow-release fertilisers. The potential toxic metals in the groundnut and sheanut shell biochars have values that suggested low contamination and less potential ecological risk making the biochars ecofriendly. Groundnut and sheanut shell biochars can be used in fields as an adsorbent and a soil amendment based on its chemical characteristics.","PeriodicalId":39601,"journal":{"name":"Annals of Agri Bio Research","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84986229","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}

We isolated Aspergillus fumigatus IB-A1 and evaluated its ability to simultaneously produce both cellulase and amylase. Although the isolate could produce both cellulase and amylase from either soluble starch or carboxymethyl cellulose, amylase activity was higher with soluble starch while cellulase activity was higher when carboxymethyl cellulose was used as the sole carbon source. With a mixture of carboxymethyl cellulose and soluble starch, both the amylase and cellulase activities increased with increase in the ratio of soluble starch. The optima ratio of carboxymethyl cellulose to soluble starch for cellulase and amylase activities were 0.7:0.3, and 0.4 to 0.6 respectively. For practical application, the optimum ratio of carboxymethyl cellulose to soluble starch in the production medium depends on the relative composition of cellulose and starch in the substrate to be hydrolyzed. The isolate was also able to efficiently produce both amylase and cellulase from cassava peel. With 10 g/L cassava peel, the cellulase and amylase activities were 6.122± 0.320 U/ml/min and 4.342± 0.210 U/ml/min respectively. When the cells were immobilized on loofa sponge and subjected to alternating air phase- liquid phase culture, cellulase and amylase production from cassava peel increased to 8.106± 0.620 U/ml/min and 5.206± 1.24 U/ml/min respectively.

Ipomoea triloba L. has been claimed to have antidiarrheal properties. This study evaluated antibacterial properties of the ethanol / aqueous extracts and fractions of I. triloba on diarrheagenic bacteria to validate its use in trado-medical treatment of diarrhoea. Aqueous and ethanol extracts of pulverized I. triloba were prepared by cold maceration and phytochemical screening was performed using standard procedures. Diarrheagenic bacteria were isolated from twenty (20) composite diarrhoeal stool samples by community bioprospecting using appropriate selective and differential media. In vitro antibacterial activity of extracts and fractions of I. triloba was determined by the modified agar-well diffusion technique, while minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) was determined by reference standard agar-dilution technique (ADT) after re-incubation of MIC samples at 37o C for 24 h. A total of 74 isolates, belonging to six genera, were identified with their numbers and percentages of occurrence as follows: Escherichia coli, 26 (35.1%), Staphylococcus aureus, 4 (5.4 %), Pseudomonas aeruginosa, 9 (12.2%), Shigella dysenteriae, 18 (24.3%), Salmonella typhi, 8 (10.8%) and Vibrio cholera, 9 (12.2%). Flavonoids, saponins, terpenes, carbohydrates and steroids were detected in both extracts. Ethanol extracts (≥30 mm) showed more potent broad-spectrum antibacterial activity than aqueous extract (≥18 mm). The MIC and MBC values ranged from 250 to 500 mg/mL and 500 to 1000 mg/mL respectively, thus establishing a time-dependent bactericidal mode of antibacterial activity.
