Short description

Molecular hydrogen production is considered as one of the promising ways to generate ecologically clean energy from various substrates, making a significant role to the future energy technology. The combination of dark- and fermentative bacteria is a new approach in hydrogen production biotechnology, which offers the potential efficient production of hydrogen from renewable resources. This project will be focused on the attempt to obtain high hydrogen yield by pure and mixed cultures of dark-fermentative (Escherichia coli) and photo-fermentative (Rhodobacter sphaeroides, isolated from Armenian mineral springs) bacteria using carbon containing products and wastes such as distillers grains waste (a by-product of ethanol fermentation) and brewery waste. The results obtained will show the possibility of using mixed carbon substrates and various wastes as an effective source of enhanced hydrogen. They will help to understand the mechanisms and regulation pathways of bacterial metabolism via the optimization the conditions for dark- and photo-fermentative cooperation for efficient hydrogen production. The study will provide not only new more effective and cheap source of hydrogen but also solve the problem of waste utilization.
