EFFECT OF WASTE CARBON ON BIOMASS AND LIPID CONCENTRATION USING ASPERGILLUS NIGER

Archana Devi* and Dr. Rohit Sharma

ABSTRACT

Effect of different waste containing carbon source on biomass and lipid production of Aspergillus niger were sudied. Different low cost and easily available carbon based feedstock substrate such as Potato peel and Rice husk was characterized and used as carbon source. These feedstocks were used for the culturing of Aspergillus niger. There was a significant difference in the lipid accumulation process as related to these carbon sources. It was found that, increase in biomass concentration increased the lipid production when the oleaginous fungal species Aspergillus niger were cultivated in media containing potato peel as waste carbon source. The lipid extracted (%) was found to be 66.2% in Potato peel, 58.3% in Rice husk and 61.6% control. This show that the oleaginous fungal species Aspergillus niger has an potential to cultivate in waste carbon sources and reduces the production cost. This process leads to the integrated process for production of alternative fuel with integration of waste management.
