Irvingia gabonensis O’Rorke Baill leaf is used in herbal medicine for treatment of a number of ailments. This study was therefore carried out to investigate the proximate composition, antinutritional factors, mineral composition and amino acid profile of Irvingia gabonensis O’Rorke Baill leaf. The proximate and antinutritional factors analyses were done using standard procedures. The mineral analyses were done using flame photometry, titrimetic method, molybdo vanadate method and atomic absorption spectrophotometry and the amino acid profile was done with the aid of Applied Biosystems PTH amino acid analyzer. Results of proximate analyses were carbohydrates (75.15±1.29 %), protein (11.43±1.07 %), fat (1.99±0.74 %), fibre (4.89±0.61 %), ash (6.71±0.28 %), moisture (5.12±0.03 %) and caloric value (364.30±5.95 Kcal). Antinutrients (phytate, oxalate and cyanide) levels in the leaf were also very low. Results from mineral analyses obtained revealed that the leaf is also a very rich source of calcium, potassium, sodium, magnesium and so on. Compared with the World health organization (WHO) standards, results of the amino acid profile showed that the leaf is very rich in isoleucine, leucine, lysine, phenylalanine, threonine, valine and tyrosine which are nutritionally essential amino acids. Furthermore, extraction of the leaf using ethanol reduced the levels of these amino acids but not below the recommended WHO standard levels for most of the essential amino acids. Irvingia gabonensis O’Rorke Baill leaf is therefore a potential source of key nutrients.","PeriodicalId":119953,"journal":{"name":"International Journal of Advances in Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131084406","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}

All the isolates (VS1, VS2, VS3, VS4) were Gram –ve, rod shaped. Antibiotic test revealed VS2 to be resistant to ampicillin and VS4 was resistant to both ampicillin and kanamycin; otherwise all the isolates were sensitive to chloramphenicol. Nitrogen fixation was studied by the estimation of total nitrogen and available nitrogen fixed by cultures in the medium and compared with the control culture of Azotobacter CBD15 (Azo) procured from IARI. VS2 and VS3 fixed 12.02 ppm/ml and 10.635 ppm/ml as available nitrogen content and 14.44 ppm/ml and 18.73 ppm/ml as total nitrogen content. 16S rDNA studies revealed identification of the isolates- Pseudomonas sp. (VS2) and Paenibacillus sp. (VS3 and VS4). VS3 and VS4 showed 98% similarity with P. borealis . Soils from which these microbes isolated were also characterized to understand the environment of these microbes. The pH and chemical characterization (Organic Carbon, Phosphorus, Sulphur, heavy metal analysis of different metals e.g. Zn, Cu, Cr, Pb, Ni and water holding capacity) of the soils showed them to be slightly alkaline and clayey loamy. Cloning of VS2 was done successfully with plasmid pMMB277 isolated from E. coli 2842.The significance of this study lies in the isolation of those bacteria which are comparable in their nitrogen fixing potential to Azotobacter .","PeriodicalId":119953,"journal":{"name":"International Journal of Advances in Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129436358","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}

Microbial enhanced oil recovery is one of the most important tertiary recovery processes. The aim of this work was to evaluate the surface activity properties of surfactin and mannosylerithritol lipids-B. In our previous studies, surfactin and mannosylerithritol lipids were produced using cassava wastewater as substrate and then purified by ultrafiltration. Thus, this work extends our previous studies. Experiments of surface activity under extreme conditions (temperature, ionic strength and pH), oil displacement, removal of oil from sand and emulsification index were carried out. Central composite rotational design was performed under extreme conditions of temperature, pH and ionic strength. The results indicated that ionic strength significantly affected the surface activity of surfactin. On the other hand, ionic strength, but also temperature and pH significantly affected the tenso activity of mannosylerithritol lipids-B. Regarding oil displacement test, mannosylerithritol lipids-B showed higher clear zone than surfactin. Contrary, in the experiments of removal of crude oil from sand, minimal differences were observed between surfactin and mannosylerithritol lipids-B. Therefore, both surfactin and mannosylerithritol lipids-B showed good surface activity under extreme conditions. In addition, it seems that mannosylerithritol lipids-B is subtly better than surfactin for microbial enhanced oil recovery.","PeriodicalId":119953,"journal":{"name":"International Journal of Advances in Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130679073","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}
