In this paper, efficient production of ethanol from corn by using fermentation process is discussed. A mathematical model is developed for the above-mentioned process and the challenges in adjusting the specific growth rate(μmax) has been addressed. Also, the rate or velocity of growth of the microbial cells which is the key affecting factor of the substrate concentration is adjusted for optimum results. On successful design of the mathematical model, the concentration of ethanol is controlled by using four different controllers out of which one suitable controller is considered as the ideal controller for the production of ethanol from corn

A bioenergetic installation with a solar heating system for individual use designed for the processing and disposal of agricultural waste of organic origin with the production of biogas and liquid high-quality organic fertilizers under conditions of anaerobic fermentation was developed and built.
Its structural scheme and the principle of operation of individual parts of this installation are presented. Particular attention has been paid to the use of solar and accumulated solar energy for heating the substrate in the reactor.
The article presents the results of studies on the release of biogas from cattle manure and manure at various temperatures of anaerobic digestion. The data presented are the basis for choosing the optimal fermentation temperature in a small-scale biogas plant, as applied to small individual farms.
The robot shows the main parameters of the proposed biogas plant. In view of the application of this technology in a small biogas plant, it is most rational in terms of the ratio of the cost of heat to energy and output biogas.

Gamma-Aminobutyric Acid (GABA): A versatile bioactive compound

γ-Aminobutyric acid (GABA) is a potent bioactive compound, which has immense market demand due to its important physiological functions and positive health effects which aid in treatment or prevention of many diseases. The main physiological effects of GABA include neuronal modulation to improve nervous system disorders, regulation of anxiety, sleeplessness, mood disorders, protection against hypertension, diabetes, nephrotoxicity and cancer. It is most commonly produced via decarboxylation of glutamate by glutamic acid decarboxylase and this pathway is operational ubiquitously in plants, microbes and humans. However, lactic acid bacteria (LAB) have emerged as the efficient clade for GABA production and is most widely used for producing GABA-enriched products by fermentation. The present review addresses the importance of GABA as a therapeutic target as well as nutraceutical for providing various health benefits. The aspects related to its production by microbial fermentation have been elaborately discussed. Further, its newly emerged role as C4-platform chemical for production of bioplastics has been encompassed in its novel applications.
