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). […]

STRAIN IMPROVEMENT

STRAIN IMPROVEMENT Strain improvement is defined as the process of improving the production and yielding capacity of a microorganism through certain (deliberate) technological, microbiological, biotechnological, or biochemical process. Microorganisms of industrial importance must possess some certain qualities– which will determine their usage for industrial productions. After their isolation from their natural habitat or environment, the

PREPARATION OF INOCULUM FOR FERMENTATION PROCESS

Microorganisms for industrial production are usually sourced naturally from their natural habitat or purchased in their pure forms from culture collection organizations such as the American Type Culture Collection (ATCC). After their purchase or isolation, the industrial microbes must be prepared through inoculum preparation techniques which activate these organisms prior to their usage for fermentation.

STERILIZATION TECHNIQUES IN INDUSTRIAL MICROBIOLOGY

Sterilization is defined as any process by which objects, materials or an environment may be rendered sterile (i.e. completely free from all forms of life). Sterilization is the process by which all living cells, viable spores, viruses and viroids are either destroyed or removed from an object or habitat. It is essential for all fermentation

LACTIC ACID BACTERIA (LAB)

Lactic acid bacteria (LAB) are a group of Gram positive, non-sporing bacteria that carryout lactic acid fermentation of carbohydrates or sugars. Lactic acid fermentation is a type of fermentation carried out by LAB in which sugars including glucose, lactose and pentoses are converted to lactic acids or a mixture of lactic acids and other products.

SACCHAROMYCES CEREVISIAE

                 Saccharomyces cerevisiae is a unicellular yeast cell that is found in the Kingdom fungi (singular: fungus). S. cerevisiae is found in the genus Saccharomyces and family Saccharomycetaceae. Morphologically, the cells of S. cerevisiae are ellipsoidal or cylindrical; and they can be propagated in the laboratory on simple mycological media such as Sabouraud dextrose agar

PROCESSES OF BEER PRODUCTION

MALTING STAGE Malting is defined as a controlled partial germination of the cereal grain or barley. Malting helps to develop amylases and proteases in the barley. Malting is the first of the enzymatic process involved in beer production; and the enzymes that malting develops in the grains bring about the chemical conversions of all the

POTENTIALS OF MICROBES IN FOOD PRODUCTION

Microorganisms inclusive of bacteria and fungi play tremendous roles in sustainable agriculture. And these organisms used for food production including bacteria and fungi have been found to improve the health status of the consumers. Due to the prevailing shortage of food or food scarcity in some parts of the world; microbes are currently being applied

PRINCIPLES OF FOOD HYGIENE: sources of contamination in food industries

Food meant for human and animal consumption must meet certain quality and safety criteria to be adjudged safe for consumption after production. And this is only possible if the production process follows certain guidelines which are all geared towards ensuring the safety and hygiene of the final product. Several factors affect the quality of food
