This present study investigated the biocontrol abilities of individual species of bacteria and their consortium against phytopathogenic Fusarium oxysporum and Rhizoctonia solani. Results from the in-vitro bio-control assay (Hydrogen cyanide, catalase enzyme, lipase enzyme and indole acetic acid production) revealed that four isolates (SB2, PL3, MPT2 and SLD3) exhibited highest and consistent bio-control characteristics. The greenhouse evaluation of these isolates and their consortium (CST) in association with tomato (Beske variety) revealed that isolate SB2 (94.9%) highly reduced the disease caused by Rhizoctonia solani than CST (91.5%), PL3 (90.5%), MPT2 (74.9%), SLD3 (71.5%) and control (0.0%). However, isolate SB2 (100%) apparently reduced the disease caused by Fusarium oxysporum, while isolates PL3, CST, MPT2, SLD3 and control reduced the same disease by 95.7%, 93.0%, 79.0%, 65.2% respectively. Isolates SB2 identified as Bacillus subtilis was the most effective and could serve as biocontrol agents for controlling Fusarium oxysporum and Rhizoctonia solani in tomato cultivation.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"17 1","pages":"219-227"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85047482","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 study was aimed at determining the prevalence of Salmonella-bacteraemia and diversity of bacterial uropathogens in concomitant urinary schistosomiasis in Jaba LGA, Kaduna State, Nigeria. Awareness on the diseases was created in pre-selected primary schools from 10 villages in Jaba. 505 pupils participated; 10ml urine and 2ml blood samples were collected from each pupil. Blood samples were pre-enriched in Selenite-F broth and Brilliant-Green-Bile broth. Urine sediments and pre-enriched blood were cultured on SSA and XLD agar. Bacterial isolates were biochemically characterised. Centrifuged urine sediments were microscopically examined for Schistosoma haematobium egg(s) and count/10ml urine was recorded. Results/data obtained were statistically analysed at P=0.05. No Salmonella species was found in all examined samples, hence a prevalence of 0.0%. Equally, no bacterial growth was seen on blood cultures. Seven diverse Gram-negative bacteria were isolated from the urine samples. Citrobacter spp (6.7%) and Klebsiella spp (3.4%) were most prevalent bacteria; others were Acinetobacter spp (2.0%) and E. coli (1.6%). The least occurring were Pseudomonas aeruginosa (0.4%), Providencia spp (0.2%) and Serratia marcescens (0.2%). Citrobacter spp (8.1%), E. coli (1.6%) and Klebsiella spp (1.6%) were found in co-infection with Schistosoma haematobium. Overall concomitant urinary schistosomiasis was 12.3%. Citrobacter spp, E. coli and Klebsiella spp were more prevalent in females. Acinetobacter spp was prevalent in males. Drinking water sources were statistically associated with bacterial uropathogens. Concerted efforts are required to eradicate schistosomiasis in Nigeria through snails/cercariae control, awareness and potable water supply.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"1 1","pages":"228-239"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89349784","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}

Results showed that the most elevated nitrate uptake was assessed after 1h (9.029 μmol gFW h) under 300 μM concentration and phosphorus uptake rate demonstrated the most outstanding uptake rate in same time under 50 μM phosphorus (3.89 μM gFW 1 h). The highest uptake rate of ammonium was evaluated after 1h as (17.01 μM gFW h) under 500 μM concentration. While, phosphorus results showed highest uptake rate under 50 μM (5.80 μmol gFW h). Furthermore, in second part nutrient uptake rates revealed increasing trend with increasing light intensity. The maximum uptake of ammonium, nitrate and phosphate is 3.06, 1.97 and 0.39 μMl gFW h respectively under 150μmol photons m s in the first hour of experiment.

This widespread use of pesticides for agricultural purposes has resulted in the persistence of their residues in various environmental matrices, such as soil, water and air. To remove these residues from the environment bioremediation has been proven a suitable technique for reducing pesticide contamination as microorganisms are capable of mineralizing them completely. Chlorpyrifos is a broad spectrum moderately toxic organophosphorous insecticide. It is widely used in agriculture for pest control and in households as a termicide. Long term exposure to chlorpyrifos residues and its metabolites can affect the human health. A microbial consortium that can utilize Chlorpyrifos as a sole source of carbon and energy was isolated from soil through a novel technique involving an initial enrichment in a column reactor followed by enrichment in a shake flask. A diverse range of microorganisms responsible for Chlorpyrifos degradation has been developed. In the present investigation, a new microbial consortium degrading Quinolphos has been developed. Factors such induction, inoculum level, concentration of the substrate, soil pH, soil moisture etc affecting degradation were also studied. Inoculum level of 500µg protein/mL, and a pH 7.5 at ambient temperature (26–28 ?C) resulted in degradation of Chlorpyrifos upto 50ppm.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"8 1","pages":"164-172"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76326752","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 lake faces a lot of environmental challenges which affect its water quality status. The main objective of this study is assessing the water quality status of the lake using an appropriate Water Quality Index (WQI). Records for twelve water quality parameters during the period from August 2010 to August 2012 were collected from 11 stations in the lake and from 4 stations at the drains outlets. Two Water Quality Indices (National Sanitation Foundation WQI and Lagoon WQI) and a GIS tool were used to assess and spatially assign the water quality conditions of the lake. The results reveal critical water quality conditions for the lake. The eastern and southern zones of the lake have the worst water quality conditions, ranking as a \"Very Bad\" water quality status, according to L-WQI. While the western zone of the lake has the best water quality condition, which is \"Good\", according to L-WQI. Bahr Elbaqar drain has the worst water quality status \"Very Bad\", among the studied drains, which affect the water quality conditions of the lake, in particular the eastern zone of the lake. The worst water quality status of the lake was recorded in August 2011, according to both used indices. The spatial assigning of the lake water quality conditions ensures that the lake should be divided into different zones for fishing and other objectives. An urgent water quality management strategy should be implemented for the lake.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"20 1","pages":"196-207"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81945431","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}
