Effect of different carbon sources on l(+) -lactic acid production by Rhizopus oryzae

Production of Edible Fungi from Potato Protein Liquor (PPL) in Airlift Bioreactor

“…The disappearance of raffinose with an increased sucrose concentration suggests the fungal ability to break the linkage between galactose and glucose but not the glucose-fructose linkage. The result is in agreement with Bulut et al, who have also described the poor metabolization of sucrose by R. oryzae strain [38].…”

Biotechnological production of lactic acid integrated with fishmeal wastewater treatment by Rhizopus oryzae

“…Recently, new applications of lactic acid, as a monomer in biodegradable and biocompatible polylactate polymers, an environment-friendly alternative to biodegradable plastics or as an intermediate in the synthesis of highvolume oxygen-containing chemicals, have the potential to greatly expand the market for lactic acid, if more economical production processes could be developed [1][2][3]. The efficiency and economics of the ultimate lactic acid fermentation is however still a problem from many points of view and media composition play a vital role in the improvement of such a process [4]. Much research has consequently focused on finding cheaper supplements such as whey, molasses, starch, beet-and cane-sugar and other carbohydrate-rich materials for the lactic acid production [1][2][3]5].…”

Fermentative production of L(+)‐lactic acid from starch hydrolyzate and corn steep liquor as inexpensive nutrients by batch culture of Enterococcus faecalis RKY1

“…At a critical substrate concentration, the reduced water activity combined with plasmolysis alters the metabolism of the organism, which reduces the utilization of available substrate. 18,19 In addition to higher initial substrate, end product inhibition is also an important reason for low productivities in batch fermentations.…”
