In this article we will discuss about:- 1. Discovery of Lactic Acid 2. Fermentation of Lactic Acid 3. Medium and Manufacturing Process 4. Recovery 5. Uses. Discovery of Lactic Acid: Lactic acid was first discovered by Scheele (1789) from sour milk. Later on, Pasteur (1857) identified the microorganism involved in lactic acid production. In the year 1881, first commercial production [...]
The following points highlight the five main steps involved in developing producer strains. The steps are: 1. Isolation of Industrial Microorganisms 2. Screening for New Products 3. Identification of Metabolites 4. Maintenance of Microbial Isolates 5. Strain Improvement. Step # 1. Isolation of Industrial Microorganisms: The first step in developing producer strains is the isolation of concerned microorganisms from their [...]
The following points highlight the four main types of industrial fermentations processes. The types are: 1. Solid State 2. Anaerobic 3. Aerobic 4. Immobilized Cell Fermentations. Type # 1. Solid State Fermentation: In industrial fermentations, microbial growth and product formation occur at the surface of solid substrates. Examples of such fermentations are mushroom cultivation, mould-ripened cheeses, starter cultures etc. More [...]
