There are three variations of the fermentation process. In batch fermentation, a sterilized nutrient solution in the fermentor is inoculated with micro-organisms and incubation is allowed to proceed. During the course of the fermentation, oxygen is added (as in the case of aerobic microorganisms) and an acid or base to control the pH. The composition of the culture medium, the biomass concentra...

Vitis hybrid (Sheridan)-Robus coreanus red wine was vinified by fermentation of a mixture of Vitis hybrid and Robus coreanus must at 25℃ for 10 days. The Vitis hybrid-Robus coreanus red wine had ethanol contents of 10.9%. It had high antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity of 57.8% and antioxidant activity of 64.8%. Changes in the physicochemical properties an...

Tea colour determination during fermentation is a vital problem in the tea industries. The human experts have been traditionally measuring change of colour during fermentation by picking up some amount and observing the colour by eye approximation. Methods are also available for analyzing the formation of colour constituents during fermentation. Another method uses colorimeter for determining t...

Local feed resources, particularly low-quality roughages and agricultural crop-residues, are of prime importance for ruminants raised in the tropics. These feeds exhibit close relationships with rumen ecology, microbes and rumen fermentation patterns. A number of dietary factors could influence rumen fermentation especially the basal roughage source, its physical form and fermentation end-produ...

The present study deals with the production of L Brevibacterium spp. The permeability of cells decide the extent of excretion of L which was modified using yeast extract, limitation of biotin and electropration. The amino acid concentration produced by fermentation was found to be 162mg /100 ml detected b spot in TLC. At 8 % culture density the yield was higher.(27.3mg/10 ml), 35 optimum for ma...

In deceptive pollination, insects are bamboozled into performing nonrewarded pollination. A prerequisite for the evolutionary stability in such systems is that the plants manage to generate a perfect sensory impression of a desirable object in the insect nervous system [1]. The study of these plants can provide important insights into sensory preference of their visiting insects. Here, we prese...

BACKGROUND Cordyceps sobolifera (C. sobolifera) isolated from cicadae was used as the starting fungus to produce selenium-enriched C. sobolifera extracellular polysaccharide (Se-CEPS). An orthogonal experimental design based on a single-factor experiment was used to optimize the C. sobolifera fermentation conditions, including the potato juice, peptone, and KH2PO4 concentrations. Ultraviolet (U...

Recently emphasis has been given to produce fermented milk with significant quality and improved health characteristics. In Ethiopia, a large proportion of milk is consumed in the fermented form through the application of traditional fermentation methods. The main fermented milk products include ergo (sour milk), ititu (milk curd), ayib (cottage cheese), neter kibe (spiced butter), kibe (tradit...

“Cancer, above all other diseases, has countless secondary causes. But, even for cancer, there is only one prime cause. Summarized in a few words, the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar. All normal body cells are thus obligate aerobes, whereas all cancer cells are partial anaerobes.” This is how Otto Warburg, at ...
