Environmental MicrobiologyAeromonas Species from Nonchlorinated Distribution Systems and Their Competitive Planktonic Growth in Drinking WaterThe occurrence of the bacterial genus Aeromonas in nonchlorinated drinking water in the Netherlands is regarded as an indication of elevated microbial regrowth in the distribution system. Identification of the prevalent species in 10 distribution systems by genotyping yielded seven different species, with A. rivuli, A. veronii, and A. sobria being the most dominant ones.
Microbial EcologyArid Ecosystem Vegetation Canopy-Gap Dichotomy: Influence on Soil Microbial Composition and Nutrient Cycling Functional PotentialIncreasing aridity will drive a shift in desert vegetation and interspace gap (microsite) structure toward gap expansion. To evaluate the impact of gap expansion, we assess microsite effects on soil nutrients, microbiome community composition and functional capacity, and the potential of gap soils to serve as microbial reservoirs for plant root-associated microbiomes in an arid ecosystem.
Food MicrobiologyStaphylococcal Enterotoxin Gene Cluster: Prediction of Enterotoxin (SEG and SEI) Production and of the Source of Food Poisoning on the Basis of vSaβ TypingBesides the infection properties in human and animals, S. aureus can produce different enterotoxins in food. The enterotoxins can cause vomiting and diarrhea, often involving many people.
Genetics and Molecular BiologyA Viability Quantitative PCR Dilemma: Are Longer Amplicons Better?Viability quantitative PCR (v-qPCR) has evolved into a valuable, mainstream technique for determining the number of viable microorganisms in samples by qPCR. Amplicon length is known to be positively correlated with the ability to distinguish between live and dead bacteria but is negatively correlated with qPCR efficiency.
Enzymology and Protein EngineeringNew Family of Carbohydrate-Binding Modules Defined by a Galactosyl-Binding Protein Module from a Cellvibrio japonicus Endo-XyloglucanaseThis study reveals carbohydrate-binding module family 88 (CBM88) as a new family of galactose-binding protein modules, which are found in series with diverse microbial glycoside hydrolases, polysaccharide lyases, and carbohydrate esterases. The definition of CBM88 in the carbohydrate-active enzymes classification (http://www.cazy.org/CBM88.html) will significantly enable future microbial (...
