  • Patent number: 12168762
    Abstract: The present invention relates to a process for producing enriched algal biomass having high lipid productivity. More particularly, the present invention provides a process for obtaining an enriched biomass with omega-3 fatty acids by using a microalgal strain Schizochytrium MTCC 5890 in a unique media composition and substrate residual band in a steady state continuous fermentation. The process of the present invention results in high biomass and lipid productivity.
    Type: Grant
    Filed: November 15, 2022
    Date of Patent: December 17, 2024
    Assignees: Indian Oil Corporation Limited, Department of Biotechnology
    Inventors: Anshu Shankar Mathur, Preeti Mehta, Rekha Rani, Ankita Kandpal, Ravi Prakash Gupta, Suresh Kumar Puri, Sankara Sri Venkata Ramakumar
  • Patent number: 12065625
    Abstract: The present invention provides a method for the simultaneous enhancement in biomass and lipids containing omega-3-fatty acids of Thraustochytrid microalgae in a single step using synergistic effect of chemical mixture in appropriate proportion in production medium. The process discloses enriching the biomass of microalgae with high value lipids by subjecting the microalgal cells in growth medium supplemented with unique combination of chemical modulators and carbon substrates in the presence of nitrogen. The present invention also provides a novel strain Schizochytrium sp. (MTCC 5980) for use in continuous aerobic fermentative lipid production process for enhancing high value lipids like Docosahexaenoic acid (DHA), Docasapentaenoic acid (DPA), Eicosapentaenic acid (EPA) and lipids for biodiesel.

  • Patent number: 9890402
    Abstract: The present invention relates to the continuous process of sequestration of nutrients from waste effluents released from gas fermentation plants or green-house gases emission managing plants by novel Thraustochytrids. Particularly this invention relates to the methods and systems to enhance sequestration rate and productivity of the process. This invention also relates to rapid biotransformation of nutrients present in waste effluents into high value omega-3 fatty acids like Docosahexaenoic acid (DHA), Docosapentaenoic acid (DPA), Eicosapentaenoic acid (EPA) and lipids for biodiesel. This disclosure is about means of processing of waste streams and producing value added products out of it.

  • Patent number: 7622636
    Abstract: The present invention relates to a method of producing salt-stress tolerant plants by transforming the plants with an isolated nucleic acid sequences encoding a dehydrin (DHN) protein. The invention further provides a transgenic plant expressing the dehydrin gene of Avicennia marina. Using functional genomics, this gene was derived from large-scale EST sequencing of the cDNA library of the salt tolerant mangrove Avicennia marina.
