Enzymes in culture filtrates of Rhizoctonia solani Kuhn grown using 4-day old or 20-day old bean (Phaseolus vulgaris L.) hypocotyl cell walls as a carbon source degraded xylan, galactan, galactomannan, araban, polygalacturonic acid, and carboxymethylcellulose. Extracts of lesions from R. solani infected plants, but not healthy plants, contained similar enzymatic activities. These enzyme sources...
The cell walls of Staphylococcus aureus are capable of inactivating S. aureus bacteriophage. Furthermore, the cell walls isolated from S. aureus of a given phage type inactivate a variety of different staphylococcal bacteriophages. Under the conditions employed neither the isolated mucopeptide nor teichoic acid components of the cell walls act as bacteriophage receptor.
Several independent experiments suggest that cell walls of Bacillus subtilis are protonated during growth. When cells were grown in the presence of fluorescein-labeled dextran to saturate the cell walls, centrifuged, and suspended in PBS, fluorescence-activated cell sorter analyses revealed the bacteria were only poorly fluorescent. In contrast, when the bacteria were purged with N(2) to dissip...
Cost-effective production of lignocellulosic biofuel requires efficient breakdown of cell walls present in plant biomass to retrieve the wall polysaccharides for fermentation. In-depth knowledge of plant cell wall composition is therefore essential for improving the fuel production process. The precise spatial three-dimensional (3D) organization of cellulose, hemicellulose, pectin and lignin wi...
Biotechnology of microalgae represents a very attractive alternative as a source of energy and substances of high value when compared with plant cultivation. Cell walls of green microalgae have an extraordinary chemical and mechanical resistance and may impede some steps in the biotechnological/industrial exploitation of algae. The aim of the present contribution was to check the presence of po...
