Research ArticleOpen accessPhrase in the titleModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon ImpellerMohd Shamzi Mohamed, Rosfarizan Mohamad, Ramakrishnan Nagasundara Ramanan et al.Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of kLa upon specific power uptake, superficial gas … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,167 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProduction of Selenium-Enriched Yeast (Kluyveromyces marxianus) Biomass in a whey-based Culture MediumNicolás Gurdo, Mario Calafat, Diego Gabriel Noseda, Isabel GigliTwo important aspects of agriculture intensification are the reduction in the concentration of specific soil minerals that affects livestock production and the increase of agricultural by-products, which produce environmental pollution. In this regard, whey - a cheese by-product-often is considered a wasted-product. Due to its lactose concentration, (4.5%), when whey is discarded without treatment generates a high Biological Oxygen Demand … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 28 Jun 2018 · 11,375 accessesView PDF Cite
