Methanobacterium

Methanobacterium In taxonomy, Methanobacterium is a genus of the Methanobacteriaceae. Contrary to their name, they are not exactly a bacterial species as they belong to the archaea and have the distinguishing biopolymer, peptidoglycan, missing from their cell membranes. Methanobacterium are nonmotile and live without oxygen. Some members of this genus can use formate to reduce methane; others live… Read More »

Lysinibacillus fusiformis

Lysinibacillus fusiformis Introduction: Lysinibacillus fusiformis (commonly abbreviated L. fusiformis) is a gram-positive, rod-shaped bacterium of the genus Lysinibacillus. Scientists have yet to completely characterize this microbe’s pathogenic nature. Though little is known about this organism, several genome sequencing projects for various strains of L. fusiformis are currently underway. History: Lysinibacillus fusiformis was initially isolated from the surface of… Read More »

Geobacillus stearothermophilus

Cell structure Geobacillus stearothermophilus (previously Bacillus stearothermophilus)[1][2] is a rod-shaped, Gram-positive bacterium and a member of the division Firmicutes. Ecology The bacterium is a thermophile and is widely distributed in soil, hot springs, ocean sediment, and is a cause of spoilage in food products. It will grow within a temperature range of 30 to 75°C. Some strains are… Read More »

Cell wall

Cell wall The cells of plants and algae, fungi and most chromalveolates have a cell wall, a layer outside the cell membrane, providing the cell with structural support, protection, and a filtering mechanism. The cell wall also prevents over-expansion when water enters the cell. The major polysaccharides making up the primary cell wall of land plants are cellulose, hemicellulose, and pectin. The cellulose microfibrils are linked via hemicellulosic tethers to… Read More »
