Thus, various strategies have been opted to investigate cost-effective solution to contaminated sites and an example is bio-stimulation. The study investigated effect of organic and inorganic nutrients on soil biological indicators of diesel – contaminated soil. The parameters investigated include determination of pH, conductivity, nitrate, phosphate, total organic carbon, moisture content, temperature, baseline, soil respiration, dehydrogenase activity, urease activity, soil microbial biomass carbon, protease activity, germination index (GI), total viable count technique (THBC and TCHUB), microscopic and biochemical characteristics in 56th days experimental period. The result revealed that the soil is neutral to slightly alkaline in pH, moderate in conductivity, low in nitrate, phosphate and total organic carbon contents, high in moisture content with moderate (mesophilic) temperature. The result of baseline study also revealed that soil respiration is 99.30 s days, dehydrogenase activity is 02.69 µg TPFg-1 dm (24 hr)-1), microbial biomass carbon is 02.69 mg/kg, urease activity is 24.52 µmol N-NH4 / g 2 hrs, protease activity is 36.66 µg / ml, GI is 09.24 %, THBC is 06.53 logCFU /g and TCHUB 06.73 logCFU /g. There were significant effect (P 0.05) on soil respiration, soil microbial biomass carbon, protease activity and germination index respectively by the organic and inorganic nutrients. There was negative and positive correlations between germination index, microbial count and other biological indicators measured. More so, the result revealed that the hydrocarbon utilizing bacterial isolates were Aeromonas sp., Serratia fonticola, Citrobacter freundii, Citrobacter diversus and Corynebacterium sp. Thus, application of organic and inorganic nutrients sources is suggested as a good strategy for bioremediation of diesel impacted soil.","PeriodicalId":15121,"journal":{"name":"Journal of Bioscience and Biotechnology Discovery","volume":"23 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82962311","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}

This has culminated in several pre-clinical and clinical studies that have provided the scientific basis for the efficacy of many plants used in folk medicine to improve growth performance in farm animals and treat infections. This study was carried out to investigate the chemical, mineral and phytochemical contents of garlic as a preliminary work to evaluate the influence of garlic on the performance characteristics of broiler chickens. Garlic bulbs (Allium sativum), including cloves and hulls, were obtained from the open market at Ado-Ekiti-Nigeria. The garlic bulbs were desegmented into cloves and were cut into chips. The chips were sun-dried for 3 weeks. The dried garlic chips were milled and analysed for the chemical compositions. The results obtained indicated that garlic on dry matter basis contained 4.55 mg/100g, 73.22 mg/100g and 15.33 mg/100g of moisture, carbohydrate and crude protein respectively. The crude fat was 0.72 mg/100g while crude fibre and ash were 2.10 mg/100g and 4.08 mg/100g, respectively. Garlic contained 10.19, 26.30, 10.19, 5.29, 0.001, 0.34 and 0.001 mg/100g of potassium, calcium, phosphorus, iron, magnesium, zinc and manganese respectively while lead and cobalt were below detection level.

The proximate content of the peel was analysed using standard method. Carbohydrates was 59.96%, fibre (14.03%), moisture (12.07%), fat (9.11%), ash (5.21%) and protein (1.02%). Results of this study revealed that the optimum pH in which a maximum growth (1790 ppm) of biomass was obtained was at pH 7.0 after 120 hours of incubation. The effect of Incubation temperature showed that maximum biomass growth (1145 ppm) was obtained at 37°C after 96 hours of incubation. Effect of substrate concentration revealed that biomass concentration increased with increase in substrate concentration. Maximum protein with minimal nucleic acid content was obtained at incubation temperature of 37°C. In conclusion, it may not be favourable to incubate the fermentation medium at temperature above 55°C and pH below 4.0 for production of SCP using Saccharomyces cerevisiae.","PeriodicalId":15121,"journal":{"name":"Journal of Bioscience and Biotechnology Discovery","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83269615","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}

Five iso-caloric and iso-nitrogenous diets were formulated containing 25%, 50%, 75% and 100% maize replacement with cassava peel meal (tagged diets B25, C50, D75, E100). The control was tagged diet A0. Two sets of experiment were designed using the formulated diets. One set, which lasted for 10 days, was designed to monitor the apparent protein digestibility of the diet and the second one to evaluate the growth, nutrient utilization (MWG, FCR, SGR) and the biochemical composition of the fillets of the fish, fed for a period of 8 weeks, in the laboratory. Fermentation significantly reduced (p 0.05) higher than those of the fish fed diets B25 and C50, but were significantly (P 0.05) from one another. The results revealed that 50% replacement of maize with cassava peel meal (diet C50) can be tolerated by C. gariepinus, without compromising growth, nutrient utilization and digestibility. The percentage survival of the fish fed the control, test diets B25, C50 and D75 were not significantly different (p>0.05) but were significantly different from those fish fed diet E100. It can be concluded that replacing maize with up to 50% replacement level of cassava peels fermented with wastewater from the fermented cassava pulp is not deleterious to growth and nutrient utilization of C. gariepinus. Fermentation might have thus reduced the toxicity and increased the nutrient value of the cassava peels, otherwise regarded as agricultural wastes, and placed it among basal feedstuffs, suitable for replacing maize in C. gariepinus diet.","PeriodicalId":15121,"journal":{"name":"Journal of Bioscience and Biotechnology Discovery","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85021310","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}
