Type VII secretion systems (T7SSs) are poorly understood protein export apparatuses found in mycobacteria and many species of Gram-positive bacteria. To date, this pathway has predominantly been studied Mycobacterium tuberculosis, where it shown to play an essential role virulence; however, much less is evolutionarily divergent subfamily T7SSs referred as the T7SSb. The T7SSb major phylum Firmi...

Probiotic Lactobacillus strains are widely used to benefit human and animal health, although the exact mechanisms behind their interactions with the host and the microbiota are largely unknown. Fluorescent tagging of live probiotic cells is an important tool to unravel their modes of action. In this study, the implementation of different heterologously expressed fluorescent proteins for the lab...

Strategic Plan New Frontiers in Environmental Sciences and Human Health (NIEHS 2006c) seeks to " challeng[e] and energiz[e] the scientific community to use environmental health sciences to understand the causes of disease and to improve human health " (National Institutes of Health 2006). The strategic plan emphasizes, among other things, integrative research, community-linked research, and pri...

it introduced an innovative bioengineering method of consolidating incompact sand by urea-hydrolysis producing calcite cementation under the inducement of urease producing microbe. in the paper it discussed the effects of cementation methods and time on porosity and mechanical properties of microbe-inspired cementing sand columns. method a adopted reaction fluid gravitational permeating and ext...
