bacillus sp. sbs25, a gram positive bacteria isolated from soil was found to be effectivein the biodegradation of natural rubber latex. the products of latex biodegradation were separated from the ether extract by thin layer chromatography. gas chromatography and mass spectrometry showed the biodegradation of the major compound into three simpler fractions with low molecular weights. this was f...

this study investigated the cytochemical responses in hediste diversicolor exposed to the environmental concentrations of cadmium (1µm cd), copper (1µm cu) and to their equimolar mixture for 48h. lysosomal membrane stability (lms), neutral lipids (nl) level, lipofuscin (lf) content and ca2+-atpase activity were determined as early subcellular biomarkers of toxicity. the biomarker battery pointe...

We have examined the lipids of three isolates, Romboutsia lituseburensis, Romboutsia ilealis, and Romboutsia sp. strain FRIFI, of the newly described genus Romboutsia by two-dimensional thin-layer chromatography (2D-TLC) and by liquid chromatography/mass spectrometry (LC/MS). We have found three phospholipids, phosphatidylglycerol (PG), cardiolipin and phosphatidic acid in all three species. A ...

Lipids are essential components of a cell providing energy substrates for cellular processes, signaling intermediates, and building blocks for biological membranes. Lipids are constantly recycled and redistributed within a cell. Lysosomes play an important role in this recycling process that involves the recruitment of lipids to lysosomes via autophagy or endocytosis for their degradation by ly...

Lipids function as important storage compounds to maintain cellular activities. Lipids store high reducing power and energy since those biosynthetic processes require high amount of reducing cofactors and ATP. Storage lipids do not cause any chemical effect on cellular activity such as osmolarity, pH and ion strength because of its hydrophobicity. Membrane lipids such as phospholipids, caroteno...
