Abstract:

Bioinformatics is a unique field in that it incorporates many different disciplines, including biology, computer science, and statistics, to study biological data. There is a vast array of techniques that utilize bioinformatics, including pangenomics, RNASeq, whole genome metagenomics, and 16S sequencing. To study bacterial interactions, we used a model system of species interactions, Myxococcus xanthus. M. xanthus is a soil bacterium that is a known predator of other bacteria. It has one of the largest repertoires of two component systems (TCS) to respond to external stresses. TCS are a pair

Abstract:

Hydrocarbon contamination of soils has increased worldwide and bioremediation offers an attractive and environmentally friendly solution to this problem. However, the efficiency and completion of remediation must be assessed using environmental risk assessment criteria. As a result, a variety of indicators have become essential for determining and evaluating recovery of contaminated soils. In this study, microbiological and toxicological assays are used to support traditional chemical analyses, to identify a suite of assays suitable for determining a Soil Recovery Index from Pollution (SRIP).

The pH robustness of <I>lux</I>-marked <I>E. coli</I> was exploited in investigating the effect of pH on the sorption of 2,4-DCP to the bacterium. As the pH decreased, the accumulation of 2,4-DCP increased correlating with the amount of non-dissociated 2,4-DCP present, indicating that non-dissociated 2,4-DCP was preferentially sorbed. It was also shown that the toxicity of 2,4-DCP was increased at low pH values correlat

Abstract:

Microbial contamination of drinking water poses an important health risk which causes severe illnesses and epidemics. In order to improve surface and drinking water quality, the understanding of fecal pathogen contamination processes including their prevention and control needs to be enhanced. The watershed model soil water assessment tool (SWAT) is commonly used to simulate the complex hydrological, meteorological, erosion, land management and pollution processes within river basins. In recent years, it has been increasingly applied to simulate microbial contamination transport at the watersh

Biodeterioration is the least understood decay mechanisms of outdoor stone monuments. Microbial colonisation is largely determined by the properties of the stone and environmental conditions. The literature on microorganisms on outdoor stone monuments and their decay mechanisms was reviewed. For the assessment and quantification of microbial deterioration, methods that can be carried out by cultural heritage conservators with limited microbiological skills were selected and adjusted for the application on outdoor stone monuments. To this end, the total biomass was quantified by a protein assay
