Patent number: 8741628Abstract: An energy efficient process for the preparation of marine microalgae Chlorella fatty acid methyl ester (CME) from hydrolysate of deoiled cake of Jatropha (JOCH) and crude glycerol co-product stream (GL7 and GL8) along with seawater diluted with tap water (1:2). A small part of the crude glycerol layer in case of JME is processed to recover glycerol for glycerol washing and the otherwise problematic still bottom is utilized for microbial synthesis of PHAs and the rest is utilized for Microalgal conversion of JME byproducts into CME. The remaining part of the methanol-depleted glycerol layer is utilized, along with hydrolysate of the Jatropha deoiled cake (JOCH), for single-stage Microalgal production of lipids by a marine Microalgal isolate (Chlorella sp.) without the need for any other nutrients. Waste streams from the microalgal processes can be discharged directly into agricultural fields as biofertilizer or recycled back in the mass cultivation.Type: GrantFiled: September 22, 2011Date of Patent: June 3, 2014Assignee: Council of Scientific and Industrial ResearchInventors: Pushpito Kumar Ghosh, Sandhya Chandrika Prasad Mishra, Mahesh Ramniklal Gandhi, Sumesh Chandra Upadhyay, Sanjiv Kumar Mishra, Imran Pancha, Anupama Vijaykumar Shrivastav, Deepti Jain, Bhumi Shethia, Subama Maiti, Krushnadevsinh Sukhdevsingh Zala
