Bacillus licheniformis is a Gram-positive biofilm- and endospore-forming bacterium, which contaminates dairy products and can be pathogenic to humans. The draft genome sequencing for B. licheniformis strain S127 is reported here, providing genetic data relevant to the ability of this strain to sustain its survival in the dairy industry.

Abstract. Benzene is a volatile organic compound: when it contaminates a river, some of the substance will evaporate as it flows through. We examine the volumetric flow rate to find how volatilization affects the concentration levels of benzene as the substance flows through several consecutive sections of a river, using a specific example to illustrate the general method.

The partial pressure of NH3 gas estimated by Raman spectroscopy indicates that approximately 0.1% NH3 inevitably contaminates the H2 desorbed from a hydrogen storage material composed of LiH and LiNH2 at any temperature up to 400 degrees C in a closed system.

Glycosaminoglycans (GAGs) are linear negatively charged polysaccharides and important components of extracellular matrices and cell surface glycan layers such as the endothelial glycocalyx. The GAG family includes sulfated heparin, heparan sulfate (HS), dermatan sulfate (DS), chondroitin sulfate (CS), keratan sulfate, and non-sulfated hyaluronan. Because relative expression of GAGs is dependent...

The isolation of cancer epithelial cells from mouse mammary tumor is accomplished by digestion of the solid tumor. Red blood cells and other contaminates are removed using several washing techniques such that primary epithelial cells can further enriched. This procedure yields primary tumor cells that can be used for in vitro tissue culture, fluorescence-activated cell sorting (FACS) and a wide...

Abstract The first case of a severe acute respiratory syndrome caused by coronavirus-2 was reported in December 2019 China. disease spread globally quickly, causing the 2019–2021 COVID-19 pandemic. meat industry became concerned over possibility transmitting virus slaughterhouse environment. level air exchange strongly affects distribution SARS-CoV-2 aerosols within slaughterhouses. adsorption ...

Mold and mildew can develop in both indoor and outdoor gardens but tends to be more devastating indoors, and can wipe out an entire crop if it is not controlled. Ultraviolet (UV) light can be used to eradicate mold spores that accumulate on floors or that spread via air currents. The primary mold spore of concern is usually Botrytis cinerea, a ubiquitous fungi that often contaminates soil and i...
