Enhanced Fumaric Acid Production by Fermentation of Xylose Using a Modified Strain of Rhizopus arrhizus
An enhanced, xylose-utilizing strain of Rhizopus arrhizus was successfully developed via modification using media with increasing concentrations of xylose. Xylose, a relatively cheap monosugar that can be easily obtained from corncobs, rice straw, and vinasse, was the sole carbon source used for both the seed culture phase and the fermentation process. After modification, this newly improved st...
متن کاملSpecies and Varieties in the Rhizopus Arrhizus-rhizopus Oryzae Group as Indicated by Their Dna Complementarity
DNA renaturation experiments gave evidence to conclude that Rhizopus arrhizus, R. OIyzae, R. delemar, Amylomyces rou.xii, R. delemar var. minimus, R. delemar var. multiplicisporus, R. arrhizus var. delemar, R. chungkuoensis var. isqfermentarius, and R. javanicus var. kawasakiensis can be accommodated in three taxa, namely, R. arrhizus var. arrhizus, R. arrhizus var. rozedi, and R. arrhizus var....
متن کاملThe mechanism of thorium biosorption by Rhizopus arrhizus.
Inactive cells of Rhizopus arrhizus have been documented to exhibit a high thorium biosorptive uptake (170 mg/g) from aqueous solutions. The mechanism of thorium sequestering by this biomass type was investigated following the same method as for the uranium biosorption mechanism. The thorium sequestering mechanism appeared somewhat different from that of uranium. Experimental evidence is presen...
متن کاملThe Effect of DL-Malic Acid on the Metabolism of L-Malic Acid during Wine Alcoholic Fermentation
Insufficient wine acidity can affect wine quality and stability. To overcome this problem, DL-malic acid can be added to the grape juice prior to fermentation. We have investigated the effect of DL-malic acid on wine fermentations and its influence on the final concentration of L-malic acid, naturally present in grape juice. To this end yeast strains that metabolise L-malic acid in different wa...
متن کاملFrom 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...
