Fermentation processes are broadly divided into two parts viz: liquid fermentation and solid fermentation. In liquid fermentation, the microbial cells are suspended in an aqueous nutrient medium. But in solid fermentation, the microbial cells are adsorbed to a solid and nutrient rich material that supports the growth of the organism. The volume of free liquid […]

Industrial Microbiology
The phrase fermentation is derived from the Latin word “fevere” – which means “to boil”. It was first coined and used by Louis Pasteur – who used it to describe the bubbling of sugar solutions especially due to the microbial activity occurring in them. The bubbling action of the sugar (a substrate) was due to
Microbial metabolites are metabolic intermediate molecules synthesized by microorganisms during and after their growth. They are the metabolic intermediates of the biosynthetic and degradative pathways of microorganisms Microbes synthesize metabolites or metabolic intermediates at an increasing rate; and these metabolites are usually harvested or recovered by industrial processes usually at the end of the fermentation

Louis Pasteur, a French scientist was the first to report the role of microorganisms in fermentation in 1848. Though a trained chemist, Pasteur was also one of the first scientists to recognize the significance of optical isomers, and he emerged one of the greatest biologists of the 19th century. Louis Pasteur achieved distinction in organic

General Microbiology
Microorganisms have played significant roles over the years in the alleviation of diseases and infections in man, animals and plants. Most of the drugs and/or antimicrobial agents used to keep infectious microbes at bay and even vaccines used for vaccination exercises are naturally sourced from microorganisms. However, microbes also play significant roles in helping to
