From raw cassava pulp to L-lactic acid via fermentation by Rhizopus oryzae
Currently the natural crude oil depletion has been brought into awareness. This affects many industries including petrochemical manufacturing. As a result, there are many attempts to develop novel processes to produce substitutes to such petrochemical products including plastics. Polylactic acid, made from polymerization of optically pure isomer of lactic acid, is one of such examples. In addit...
متن کاملCopper Recovery from Chalcopyrite Concentrate by an Indigenous Acidithiobacillus ferrooxidans in an Air-Lift Bioreactor
In this study, effects of solid concentration, temperature, and initial Fe2+ concentration on bioleaching of sulfide mineral (chalcopyrite) obtained from Sarcheshmeh Copper Mine in the region of Kerman located in the south of Iran were investigated. A mesophilic iron oxidizing bacterium, Acidithiobacillus ferrooxidans has been isolated from a typical chalcopyrite copper concentra...
متن کاملlactic acid production with in situ extraction in membrane bioreactor
background and objective: lactic acid is widely used in the food, chemical and pharmaceutical industries. the major problems associated with lactic acid production are substrate and end-product inhibition, and by-product formation. membrane technology represents one of the most effective processes for lactic acid production. the aim of this work is to increase cell density and lactic acid produ...
متن کاملExtractive Fermentation of Lactic Acid in Lactic Acid Bacteria Cultivation: A Review
Lactic acid bacteria are industrially important microorganisms recognized for their fermentative ability mostly in their probiotic benefits as well as lactic acid production for various applications. Nevertheless, lactic acid fermentation often suffers end-product inhibition which decreases the cell growth rate. The inhibition of lactic acid is due to the solubility of the undissociated lactic ...
متن کاملKinetics of Deoxynivalenol Degradation by Aspergillus oryzae and Rhizopus oryzae in Submerged Fermentation
O objetivo foi avaliar a capacidade das espécies fúngicas Aspergillus oryzae e Rhizopus oryzae em degradar desoxinivalenol (DON) em fermentação submersa. O meio submerso utilizado foi água destilada estéril contaminada com 1mg mL DON, inoculado com 4 × 10 esporos mL das espécies fúngicas. A amostragem foi realizada a cada 48 h até 240 h de processo, determinando a massa residual de DON, percent...
