DESIGN AND OPERATION OF THE FERMENTER

A fermenter or bioreactor is simply defined as an apparatus that maintains optimal conditions for the optimum growth of microorganisms used in large-scale fermentation and in the commercial production of economically useful products. Fermenter can also mean fermentation vessel (i.e. an apparatus in which microbes including bacteria, yeasts and moulds causes fermentation to take place). […]

Benefits of Fermentation

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

MICROBIAL METABOLITES: Primary Metabolites & Secondary Metabolites

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 (1822-1895)

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

Introduction to Industrial 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
