In this article we will discuss about the biosynthesis of murein. A characteristic polymer that forms the backbone of all eubacterial cell wall is peptidoglycan or murein. Murein essentially consists of parallelly running polysaccharide chains, the repeating unit of which is a disaccharide of N-acetyl-glucosamine (NAG) and N-acetyl muramic acid (NAM) having a tetra-peptide bonded to its lactyl group. The [...]
The following points highlight the five main types of fermentation. The types are: 1. Alcoholic Fermentation 2. Lactic Acid Fermentation 3. Propionic Acid Fermentation 4. Butyric Acid — Butanol Fermentation 5. Mixed Acid Fermentation. Type # 1. Alcoholic Fermentation: Alcoholic fermentation generally means production of ethanol (CH3CH2OH). Commonly yeasts, particularly Saccharomyces cerevisiae, are used for production of various alcoholic beverages, [...]
In this article we will discuss about the regulation and control of metabolism in microorganisms. The biological organisms, specially microorganisms take up nutrients and metabolize them through numerous enzyme-catalysed reactions to build-up their body components as well as extract energy. All these anabolic and catabolic reactions run in a highly coordinated and harmonious manner to ensure optimal growth and multiplication [...]
