This paper details a numerical model developed to predict the fate and transport of faecal bacteria in receiving surface waters. The model was first validated by comparing model predicted faecal bacteria concentrations with available field measurements. The model simulations agreed well with the observation data. After calibration, the model was applied to investigate the effects of different p...

We study the transport of bacteria in a porous media modeled by square channel containing one cylindrical obstacle via molecular dynamics simulations coupled to lattice Boltzmann fluid.

Abstract Purpose Black soldier fly transforms organic waste into insect protein and fat, which makes it valuable for ecological utilization. This process is associated with the intestinal microbiota. research was developed to determine type functional characteristics of microbiota present in black larvae. Methods In this research, metagenomics has been used study larvae gut bacteria, involves h...

The movement of fecal pathogens from land to surface and ground water are of great interest because of the public health implications. Non-structural best management practices that control the timing, volume, and placement of animal manures are commonly used to limit opportunities for fecal pathogens to enter water bodies. Increased infiltration capacity, water and waste diversions, and vegetat...

Bacteria elaborate iron chelators that scavenge iron from the environment, including their human and animal hosts, and iron acquisition is a determinant of pathogenicity. One such iron chelate, the siderophore ferric enterobactin, enters Gram-negative bacteria through the FepA protein of the outer membrane. The ferric enterobactin transport process is a high-affinity, multi-specific, multi-comp...

Perhaps because we have come to accept so well the possibility of exquisite precision in biomolecular recognition in general, and by enzymes in particular, a need has arisen for re-emphasis of the limits that may apply to the possible oneto-one specificity between the mediators and substrates for the special area of membrane transport. Early studies with bacteria had bro~gh,* attention to trans...

The roles of the cell membrane as both a permeability barrier to foreign substances and as a selective filter which admits nutrient molecules have been recognized as fundamentally important to animal physiology since the first decade of this century. It was not until the 1950's, however, that microbiologists recognized that bacteria possess membrane transport systems, distinct from their metabo...
