Topic: Dioxins Bioremediation In Soil

Description: A pristine soil was artificially contaminated with 2-chlorodibenzo-p-dioxin 2-CDD and separated into three portions. Microcosms SSOC and SSCC were seeded with Bacillus sp. SS2 and a three-member bacterial consortium respectively; SSC was untreated, while heat-sterilized contaminated soil served as overall control. Significant degradation of 2-CDD occurred in all microcosms except for the control where the concentration remained unchanged. Degradation of 2-CDD was highest in SSCC 94.9% compared to SSOC 91.66% and SCC 85.9% . There was also a notable reduction in the microbial composition complexity both in species richness and evenness following dioxin contamination, a trend that nearly lasted the study period; particularly in setups SSC and SSOC. Irrespective of the bioremediation strategies, the soil microflora was practically dominated by the Firmicutes and at the genus level, the phylotype Bacillus was the most dominant. Other dominant taxa though negatively impacted were Proteobacteria, Actinobacteria, Chloroflexi, and Acidobacteria. Overall, this study demonstrated the feasibility of microbial seeding as an effective strategy to cleanup tropical soil contaminated with dioxins and the importance of metagenomics in elucidating the microbial diversities of contaminated soils. Meanwhile, the seeded organisms, owed their success not only to metabolic competence, but survivability, adaptability and ability to compete favourably with autochthonous microflora.

Resistomes in Freshwater bioaerosols

Antimicrobial resistance AMR is a global challenge issue, especially in Africa due to unregulated use of antibiotics in health and agricultural sector. The environment plays a significant role in the dissemination of AMR and also serves as hotspots of AMR. Antimicrobial resistance genes ARGs found in freshwater environment is as a result of impacted from anthropogenic activities, forming a set of genes called antimicrobial resistome in different environment. AMR in bioaerosols which has been understudied also contribute to the spread of resistant microbes.Monitoring the physicochemical parameters will enable us deduce the factors that proliferate ARGs abundance.Culturable microorganisms bacteria will be isolated from water and bioaerosol samples using appropriate culture media. In addition, they will be characterized by microscopic techniques and whole genome sequencing WGS . Culture independent methods will be used in order to identify the microbial diversity and antimicrobial resistome.Early detection of epidemic and control of diseases in drinking water. Predict the pattern of future spread of airborne ARGs on the basis of data generated.
