By-products from different industries could represent an available source of carbon and nitrogen which be used for bioethanol production using conventional Saccharomyces cerevisiae yeast. Spent cherry brine whey are acid food by-products have a high organic matter content toxic compounds, their discharges significant environmental economic challenges. In this study, combinations urea, yeast con...

High sugar concentration is more preferred in industrial bioethanol production, as it can increase the amount of ethanol produced by the end of fermentation. However, when high sugar concentration is used in the media, yeast cells are exposed to high osmotic stress, which can affect the fermentation performance. The present experiment aimed to investigate the fermentation performance of the yea...

Draksarista was prepared on experimental scale and the progress of fermentation was studied with reference to the conversion of sugars into alcohol and the attended variations in physico-chemical constants in the medium. It has been observed that a species of Saccharomyces isolated from Madhuka flowers was capable of causing fermentation in the Draksarista medium. However, its performance was l...

The loss of energy which occurs in the rumen fermentation can be very appreciable (Czerkawski, 1969) and it is therefore not surprising that efforts are being made to find ways of manipulating the fermentation to minimise this loss. The area has been reviewed by Marty, (1972), Demeyer and Van Nevel (1975) and Czerkawski (1969). In addition to the energy consideration a number of conditions exis...

The object of research is a production of antibiotics by fed batch fermentation. An intelligent system with a structure of neural network and a genetic algorithm are used in nonparametric modeling of the fermentation process. The goal is to build a model for the prediction of fermentation eeciency. A priori knowledge of experts, who are controlling the production of antibiotics in industry, is ...

Conditions for rapid fermentation of sugar in wine under pressure were sought for use in continuous production of naturally fermented sparkling wine. Wine yeast growth and fermentation were measured under CO(2) pressure. The medium was white wine with added glucose. Pressure was very inhibitory to growth, especially at low pH or high alcohol concentration. Use of various strains of wine yeast, ...
