The available information lists 1 patent and identifies Goa, India, as his location.

Latest Patents

Kumar’s listed patent, “Method for Enhancing Levels of Polyunsaturated Fatty Acids in Thraustochytrid Fungi,” describes using polyvinyl pyrrolidone (PVP) to increase the viscosity of the culture medium and enhance fatty-acid levels.

The method uses the thraustochytrid strain NIO-TH 21, identified in the patent as corresponding to the species Gaertner and associated with culture accession number AB22115 at Japan’s National Institute of Bioscience and Human-Technology. The strain is first grown in culture medium for two days at 25–30°C. The resulting culture is then used to inoculate media containing different PVP concentrations, followed by a further two to five days of growth at the same temperature range. Cells are harvested by centrifugation, and the process is intended to yield increased amounts of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).

Career Highlights

The patent reflects research focused on microbial cultivation and the production of valuable polyunsaturated fatty acids. By adjusting the culture medium with PVP, the disclosed method seeks to improve DHA and EPA levels in thraustochytrid fungi.

Collaborations

The supplied information names Dorai Rajasingam Chandramohan and Ehrlich Desa as Kumar’s coworkers. The patent work is associated with the Council of Scientific and Industrial Research.

Conclusion

Seshagiri Raghu Kumar’s listed invention applies a modified culture medium to enhance DHA and EPA production in thraustochytrid fungi, highlighting his contribution to research in microbial biotechnology.
