Owing to the presence of > 60% glucans in their cell wall structure, the present research was designed to understand the effect of nutrient regulation on growth of <em>S.pombe</em> to economize the glucan production. The study was performed using two different media; yeast extract with supplements (YES) and yeast extract-peptone-dextrose (YPD) and the YPD medium was noticed to be the best and cost-effective for maximum growth of <em>S.pombe</em>. Thereafter, a sequential optimization studies, starting with one factor at a time (OFAT) methodology followed by two step statistical approach Placket-burmann design (PBD) and Response surface methodology (RSM) improved the biomass yield from 14-34.5 g/L (1.5 fold) at shake flask level. Mass transfer of media components, temperature, dextrose and yeast extract have played significant role in metabolism mediated growth of the <em>S.pombe</em>. The major finding of the present study is non-significance of peptone in enhancing the <em>S.pombe</em> biomass. Validation of the above at bioreactor level with dextrose at 4%, rpm at 200, temperature at 28<sup>o</sup>Cand yeast extract at 2% increased the biomass yield from 34.5 - 52 g/L.</p>}, number={2}, journal={Current Trends in Biotechnology and Pharmacy}, author={Reddy Shetty , Prakasham and Batchu, Uma Rajeswari and Buddanaa, Sudheer Kumar and Thotaa, Sree Harshika and Pulivarthi, Deepthi and Cheemalamarri, Chandrasekhar and Banotha, Linga and Penna, Suprasanna and Poda, Sudhakar}, year={2023}, month={May}, pages={773–787} }
