Soil samples were collected from randomly selected from five major flower farms around Lake Naivasha basin. Four sampling points for each greenhouse within the farms were randomly selected i.e., two points within the greenhouses and two water drainage points around the greenhouses. Morphological, cultural and biochemical characterization of bacterial species isolated from the flower farm soil samples identified mainly Pseudomonas aeruginosa, Escherichia coli, Rhodococcus erythropolis and Bacillus subtilis species. Qualitative and quantitative analysis of soil samples by High Pressure Liquid Chromatography identified aldrin, dieldrin, endosulfan, dimethoate, malathion and methyl parathion as the main pesticide residues present. The bacterial isolates were grown in nutrient media and incubated with different concentration of pesticide residues depending on the mean concentration of the pesticide residues analyzed from soil samples. Analysis for biodegradation of pesticide consortia was done every 2 days, 10 days, 15 days and 21 days at 15°C in vitro. All the bacterial species were capable of degrading the pesticide residues at different level. Bioremediation can therefore be better alternative in solving pollution problems around lake Naivasha basin. The bioremediation products were identified by High Performance Liquid Chromatography.","PeriodicalId":15262,"journal":{"name":"Journal of Bioremediation and Biodegradation","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79110991","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}

Failure to comply with the local and international environmental standards, this industry will have three fates in the country: first, hides and skins will either be half processed or exported in raw form; second, tannery waste effluents will escape to the environment beyond permissible levels, posing a risk to aquatic life and human health and safety in the country; third, exporting raw hides and skins due to fear of the closure of full operation as they fail to meet compliance requirements for the tannery effluents in the country. This results into donating jobs and other products of hides and skins We propose the in-depth study of the suitability of bioremediation technology as a possible sustainable treatment technology for tannery effluents which unfortunately is not properly documented in the country.

The treatment system was sized for Hillside Farm’s 530,000 kg of annual manure production. The following systems were explored: lagoon, traditional composting, traditional anaerobic digester, anaerobic bag digester, and vermicomposting. The most practical manure treatment system was determined to be a vermicomposting system. The vermicomposting system employs Eisenia Fetida, a type of earth worm, to process the manure. The vermicomposting system consists of 12 units, each with a length and width of 4.6 m, and a depth of 0.3 m. To reduce costs and take advantage of Eisenia Fetida’s rapid reproduction ability, it was decided to initially purchase 5% of the total required worms. Each vermicomposting unit was estimated to cost $1,035, resulting in a total cost of $12,420. The primary concern for the treatment system is in regard to its performance during periods of low temperature. Eisenia Fetida’s manure processing rate declines with temperature. Hillside Farms should investigate the feasibility of installing a greenhouse or similar structure to insulate the vermicomposting units. The research paper herein contains valuable information that may assist other small farms exploring manure treatment options.","PeriodicalId":15262,"journal":{"name":"Journal of Bioremediation and Biodegradation","volume":"73 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88508394","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 in vitro biodegradation of diazinon by four bacterial strains entitled S1, S2, S3 and S4 that isolated from soil was studied in liquid medium. The High-Performance Liquid (HPLC) used for measurement of diazinon residues at successive intervals until 15 days after incubation. The results indicated that during 15 days of incubation all bacteria isolates were able to totally degrade 50 mgkg-1 diazinon in mineral salt medium (MSM) as a phosphorus and carbon sources.Diazinon Recovery rate was performed at 0.1 and 1 mg kg-1, achieved values were 80.30 and 91.80%, respectively, limit of detection (LOD) was 0.4mgkg-1 while limit of quantification (LOQ) was 0.2mgkg-1. Diazinon half-life values (DT50) were 4.66, 3.76, 3.84 and 3.87 days for S1, S2, S3 and S4, respectively and control value was 6.44 days. No significant effect on diazinon occurred with S1 (Stenotrophomonasmaltophilia), S2 (Pseudomonas Stutzeri), S3 (AlealigenSp) and S4 (Pantoaanatis) treatments showed significant effect that increased diazinon degradation rate compared to control treatment. These results highlight the potential of these bacteria to be used in the clean-up of contaminated pesticides-waste in the environment.","PeriodicalId":15262,"journal":{"name":"Journal of Bioremediation and Biodegradation","volume":"18 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79232289","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 from the laboratory microcosm experiments showed that after 60 days, the concentrations of BaP were significantly reduced by 81%, in the biodiesel amended samples compared to the 26% and 34% depletion in the control and nutrient-only amended microcosms, respectively. The 3-ring PAH anthracene was also almost completely biodegraded in the presence of biodiesel. However, phenanthrene degradation was significantly inhibited in these samples as only 3% reduction occurred as opposed to the 80% depletion observed in the control. A stepwise treatment approach conducted on the coal tar spiked soil also revealed a higher reduction in BaP (98%) in the biodiesel amended microcosms compared to the control (29%) and further enhanced the depletion of phenanthrene by 51% after 60 days of adding biodiesel to soil initially treated with nutrients. Toxicity assays showed that biodiesel amended microcosms stimulated phosphatase enzyme activity and exhibited a lower toxic response to Microtox Vibrio fischeri. Overall, the pattern observed in the removal of the PAHs using biodiesel, suggests the co-metabolic action of ligninolytic fungi, probably via lignin peroxidases, as also evidenced from the visible growth of moulds after 14 days of amendment. The enhanced removal of carcinogenic PAH and the reduced toxicity observed in soil after biodiesel amendment, indicates that this bioremediation technique has potential for full scale field trials.","PeriodicalId":15262,"journal":{"name":"Journal of Bioremediation and Biodegradation","volume":"51 1","pages":"1-13"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76913869","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}
