Cellular Respiration- Definition, Equations, Types, Steps, Products

Cellular Respiration

Cellular Respiration Definition Cellular respiration is a metabolic process consisting of a series of steps to convert chemical energy (sugar) into a usable form of energy (ATP) in the cell. The reactions involved in cellular respiration are catabolic reactions that involve the breakdown of larger organic molecules into smaller forms. The overall process of cellular respiration takes place in a …

Submerged Fermentation

Submerged Fermentation

Fermentation is the technique of biological conversion of complex substrates into simple compounds by various microorganisms such as bacteria and fungi. In the course of this metabolic breakdown, they also release several additional compounds apart from the usual products of fermentation, such as carbon dioxide and alcohol. These additional compounds are called secondary metabolites. Secondary metabolites range from several antibiotics …

Solid State Fermentation (SSF)

Schematic of solid state fermenter for conversion of lignocellulosic biomass to enzymes.

Solid State Fermentation (SSF) is a fermentation method used by several industries like the pharmaceuticals, food, textile etc., to produce metabolites of microorganisms using solid support in place of the liquid medium. It is defined as the growth of microbes without free-flowing aqueous phase. The SSF is alternative to submerged fermentation for production of value-added products like antibiotics, single cell protein, …

Louis Pasteur and his contributions

Louis Pasteur and his contributions

Louis Pasteur was a French chemist and microbiologist considered the most important founders of Microbiology. Microbiology developed as a scientific discipline from the era of Louis Pasteur (1822- 1895) himself. He first coined the term “microbiology” for the study of organisms of microscopic size. For his innumerable contributions in the field, he is also known as the Father of Microbiology. He is …

Glycolysis- Steps, ATP generation and Significance

Glycolysis- Steps, ATP generation and Significance

Fermentation and respiration are two major strategies for energy conservation in chemoorganotrophs. The glycolytic pathway is a major metabolic pathway for microbial fermentation which involves the catabolism of glucose into pyruvate. It is also called the Embden–Meyerhof–Parnas pathway for its major discoverers. Regardless of whether glucose is fermented or respired, it travels through this pathway thus it is referred to …
