A PROCESS FOR HYDROGEN PRODUCTION FROM ANACARDIUM OCCIDENTAL (CASHEW APPLE) FRUITS

摘要

The present invention provides the technology for the production of hydrogen from tropical fruit feedstock. Wherein the Cashew apple, (Anacardium occidentale) rich in reducing sugars (fructose and glucose), vitamins, minerals, and some amino acids. Citrobacter fruendii (MTCC 2420) metabolizes the organic material at elevated temperature and pH levels that are specific to the nitrogen fixing microbes. Individual colonies of Citrobacter fruendii are contained within the production system, providing a sustainable level of hydrogen production. The Citrobacter fruendii metabolites organic material in the organic feed material in substantially a 1:4 ratio with water and produces hydrogen. The environment in the production medium is preferably maintained between about 4.5 -7.5 pH. The present invention provides a simple and cost-effective way to produce by selectively harnessing hydrogen production by selectively bacteria utilizing organic sugar based solutions; it results in maximum hydrogen production with a reduced amount of energy utilization.
