Listeria monocytogenes is a food-borne pathogen capable of growth at refrigeration temperatures. Membrane lipid fatty acids are major determinants of a sufficiently fluid membrane state to allow growth at low temperatures. L. monocytogenes was characterized by a fatty acid profile dominated to an unusual extent (> 95%) by branched-chain fatty acids, with(More)
This article describes the use of biofilm reactors for the production of various chemicals by fermentation and wastewater treatment. Biofilm formation is a natural process where microbial cells attach to the support (adsorbent) or form flocs/aggregates (also called granules) without use of chemicals and form thick layers of cells known as "biofilms." As a(More)
Listeria monocytogenes is a food-borne pathogen with the ability to grow at refrigerator temperatures. Twelve cold shock proteins (Csps) with apparent M(r)s of 48,600, 41,000, 21,800, 21,100, 19,700, 19,200, 18,800, 18,800, 17,200, 15,500, 14,500, and 14,400 were induced by cold shocking L. monocytogenes 10403S from 37 to 5 degrees C, as revealed by(More)
Membrane fatty acid composition and thermal resistance (D value) of Pediococcus sp. were determined for mid-exponential-phase (ME) and stationary-phase (ST) cells grown in tryptic soy broth (TSB) and tryptone-glucose-yeast extract (TGY) at 28 and 37 degrees C. As the cells entered the stationary phase of growth, the unsaturated fatty acid, C18:1 n11c,(More)
