Última Kinetic analysis and effect of culture medium and coating materials during free and immobilized cell cultures of Bifidobacterium animalis subsp. lactis Bb 12 Electron. J. Biotechnol. Jalili,Hasan; Razavi,Hadi; Safari,Mohammad; Amrane,Abdeltif. Microencapsulation technique appears helpful for more protection of Bifidobacteria against acid inhibitory effect. The effect of medium composition and product inhibitory in free cell culture, as well as the effect of the coating materials in immobilized cells, on biomass growth, acid production and substrate utilization kinetics of Bifidobacterium animalis subsp. lactis Bb 12 in uncontrolled batch fermentation was examined. The Monod and the Luedeking and Piret equations with a product inhibition term involving toxic power terms improved model efficiency for both growth and production. The model showed that media and coating materials had an effect on toxic power terms. Cell immobilization had a positive impact on B. animalis culture. Kinetic analysis...

After building of Grand Ethiopian Renaissance Dam (GERD), significant drastic shortage in Nile water resources in Egypt is expected. This water shortage forced Egyptian farmers to use low quality water in irrigation resources impregnated with a variety of contaminants such as potential toxic elements PTEs transferred into the food chain. In a complete randomized plot design greenhouse experiment, three terrestrial soil ecosystems, collected from Abou-Rawash (Konbera), Sinai and Kafr El-Sheikh Governorates irrigated with varied types of low-quality waters for extended periods were trailed for the sake of valuation of new innovative phytoremediation practices using kinetic approach. Calculated Zinc equivalent ZE parameter, indices for soil safety for...

The extraction of phytase produced by solid-state fermentation of citrus peel was studied employing a multistage leaching process. It was observed that the extracts containing EDTA retained over 90% of phytase activity at room temperature after 24 h after the leaching. A fractional design 2² (with 4 replicates at the central point) was carried out for testing the pH and agitation as process independent factors. Only the interaction between the pH and agitation showed a significant influence. These factors were optimized with a central composite design. Agitation at 300 rpm and pH at 5.0 were the best conditions to extract the enzyme from solid matrix. The modeling of the process indicated that diffusivity of the enzyme in the solvent was the controlling...
