Cocoa beans fermentation is an important step in the post-harvest processing of cocoa beans. This complex mix culture fermentation produces metabolic products that serve as the precursors for the flavor development process. Modification in the dynamics of microbial population during the fermentation may alter the overall microbial activity and thus may impact the fermentation process. Addition ...

Control of the rumen fermentation needs a basic knowledge of the rumen microbes. This short paper provides a few examples of work on the types and metabolic characteristics of the organisms and the influence of external conditions on their growth and metabolism. The term ‘fermentation patterns’ in the rumen is generally understood to denote principally the proportions of three volatile fatty ac...

erythromycin production is clearly enhanced by the addition of vegetable oils. however,whether this positive effect is brought about by the triglyceride or non-triglyceride fraction, isnot clear. the non-triglyceride portions of the oils accumulate in the waste during the refiningprocess leaving mainly triglycerides in the refined oil. in this research, sub-fractions of soybeanoil, including le...

Thermolyzed casein is known to promote the growth of aberrant crypt foci (ACF) and colon cancer when it is fed to rats that have been initiated with azoxymethane. We speculated that the promotion was a consequence of increased colonic protein fermentation (i.e., that the thermolysis of the casein decreases its digestibility, increases the amount of protein reaching the colon, and increases colo...

Kombucha is a traditional fermentation of sweetened tea, involving a symbiosis of yeast species and acetic acid bacteria. Despite reports of different yeast species being associated with the fermentation, little is known of the quantitative ecology of yeasts in Kombucha. Using oxytetracycline-supplemented malt extract agar, yeasts were isolated from four commercially available Kombucha products...

OBJECTIVE To test the practicability of the solid-state fermentation for medicinal fungi by fermenting Ganoderma lucidum with Radix Astragali containing medium. METHODS Ganoderma lucidum was fermented in ordinary medium, drug-containing medium (containing Radix Astragali) and selenium-rich drug-containing medium respectively. The polysaccharide contents of fermentation products from the three...

Algal biorefinery process utilizes every component of algal biomass to produce multiple useful fuel products. In this technique, acid pretreatment of algal biomass hydrolyzes microalgal carbohydrates into fermentable sugars, makes lipids more extractable and a protein part accessible for additional products. In the present study, Chlorella sorkiniana produced higher quantity of biodiesel than B...

Production of lysine by Corynebacterium glutamicum (PTCC 1532) from different agricultural by-products (molasses and pulpy waste date) was compared to glucose as raw materials. For this purpose, ammonium sulphate was selected as a constant nitrogen source. The effect of different nitrogen sources was also investigated with glucose as a constant carbon source. The production of L-lysine was exam...
