Simultaneous saccharification and fermentation (SSF) is the most commonly practiced operation in lignocellulose bioconversion to avoid the sugar product inhibition to cellulase enzymes. In this study, for the first time SSF was tested on microbial lipid fermentation using the diluted acid pretreated and biodetoxified corn stover. The results show that SSF was effective than the separate hydroly...

Linseed lipid in the dietary composition is a major factor influencing the fatty acid composition of milk from ruminants, because fatty acids which reach the duodenum are, at least in part, of dietary origin as well as the result of ruminal microbial biohydrogenation of dietary lipids. In this review, the effect of linseed lipid on ruminal fatty acid metabolism, nutrient digestibility, microbia...

Growing interest in the utilization of black shales for hydrocarbon development and environmental applications has spurred investigations of microbial functional diversity in the deep subsurface shale ecosystem. Lipid biomarker analyses including phospholipid fatty acids (PLFAs) and diglyceride fatty acids (DGFAs) represent sensitive tools for estimating biomass and characterizing the diversity...

BACKGROUND Many waste streams have a relatively high vegetable oil content, which is a potential resource that should be recovered. Microbial storage compound production for the recovery of lipids from lipid-water emulsions with open (unsterilized) microbial cultures was investigated in a sequencing batch reactor using a diluted vegetable oil emulsion as model substrate. RESULTS After feeding...

Adenosine, adenine, cyclic adenosine monophosphate (AMP), AMP, nicotinamide adenine dinucleotide, adenosine diphosphate, and adenosine triphosphate (ATP) were recovered quantitatively from aqueous portions of lipid extracts of microfouling, detrital, and sedimentary microbial communities. These could be detected quantitatively in the picomolar range by forming their 1-N-etheno derivatives and a...

Lipids from microbes offer a promising source of renewable alternatives to petroleum-derived compounds. In particular, oleaginous microbes are of interest because they accumulate a large fraction of their biomass as lipids. In this study, we analyzed genetic changes that alter lipid accumulation in Rhodobacter sphaeroides By screening an R. sphaeroides Tn5 mutant library for insertions that inc...

Protozoa population, microbial synthesis efficiency and rumen degradability of dry matter and neutral detergent fiber in cattle fed on diets with different lipid rates were evaluated. Nine 16-monthold Nelore young bulls, cannulated in the rumen and duodenum, weighing 232 ± 35 kg, were used in the trial. Experimental design consisted of a 3 x 3 square in triplicate, comprising the following trea...

The route of initial entry influences how host cells respond to intracellular pathogens. Recent studies have demonstrated that a wide variety of pathogens target lipid microdomains in host cell membranes, known as lipid rafts, to enter host cells as an infectious strategy.

Microbial inhibitors for two enzymes involved in lipid metabolism, acylCoA:cholesterol acyltransferase (ACAT) and famesyl-protein transferase (FTase), were screened with assay systems using partially purified enzymes. ACAT inhibitors are expected to work as cholesterol-lowering or anti-atherosclerotic agents, and FTase inhibitors are as anticancer drugs. Three kinds of new ACAT inhibitors were ...
