Water hyacinth producing bio-hydrogen by Klebsiella oxytoca ATCC 13182 and their optimization

Abstract

Our energy requirements are almost totally provided by carbon containing fossil sources such as oil, coal and nature gas, but they cause serious environmental problems during combustion such as CO2 emission and climate changes. Bio-hydrogen production from Klebsiella oxytoca ATCC 13182 and water hyacinth was taken as a substrate. Water hyacinth are good source of cellulose and hemicelluloses content used for bio-hydrogen production. This research paper includes the effect of age of inoculation, volume of inoculation and acid pre-treatment (concentrated sulfhuric acid) on bio-hydrogen production along with their specific hydrogen production rate (SHPR), carbon consuming efficiency (CCE) and pH.
