Microorganisms are found in virtually every habitat present in nature. Even in hostile environments such as the poles, deserts, geysers, rocks, and the deep sea, some types of microorganisms have adapted to the extreme conditions and sustained colonies; these organisms are known as extremophiles. M...
Microbes and volatile organic compounds were analysed in indoor air. In addition, insulation material samples were taken from the upper and lower parts of non-ventilated outer walls for microbiological analyses. Moisture indicating and potential toxin producing microbes were present in all insulation ...

Elucidating which microorganisms are present in indoor air is fundamentally a question of community assembly. Vellend (2010) recently posited that issues in community ecology would benefit from an approach emphasizing four fundamental processes that have analogies in population genetics: selection, dispersa...
While the GI tract of the fetus was thought to be sterile, recent evidence suggests that bacteria are present in the amniotic fluid (Jimenez et al, 2008) and also the placenta (Wassenaar and Panigrahi, 2014). During the delivery process microbes are acquired from the mother's fecal and ...
We hypothesize the built environment (BE), specifically room surfaces frequently touched by humans, is a predominant source of colonizing microbes in the gut of premature VLBW infants. Here, we present the first matched fecal-BE time series analysis of two preterm VLBW neonates housed in a ...
which would be present in indoor air given certain assumptions and correction factors (described below). The indoor concentration of each ion species was estimated using a single-compartment mass balance model (Eq.1). The model assumes that the indoor air was well mixed throughout the home and...
To test whether the metabolite levels were consistent with the gene function prediction, we examined the concentrations of metabolites that were present in the three bacterial supernatants with the same OD value. The concentration of lactate was around 10 mmol/L in the LA and LR while 20 mmol/...
In the present study, an estuary reservoir with different environmental conditions was selected using time-site treatments and pyrosequencing was used to characterize whole communities. The results could provide new insight into the relationship between species and environmental conditions in estuary ...
The enteric pathogen Escherichia coli uses AI-3 produced by the microbial gastrointestinal (GI) community to activate the expression of its virulence genes, resulting in colon lesions. In enterohemorrhagic E. coli (EHEC), the eukaryotic hormones epinephrine and norepinephrine present in the GI tract ...
