In this article we will discuss about the biosynthesis of various types of nucleotides:- 1. Pyrimidine Nucleotides 2. Purine Nucleotides. 1. Pyrimidine Nucleotides: Biosynthesis of pyrimidine nucleotides begins with condensation of a carbamyl residue of carbamyl phosphate with aspartic acid to produce carbamyl aspartate and inorganic phosphate. Carbamyl aspartate is dehydrated and cyclized to dihydro-orotic acid which is next dehydrogenated [...]
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 [...]
