Approximately 10,000 different types of dyes and pigments are being used in various industrial applications yearly, which include the textile and printing industries. However, these dyes are difficult to degrade naturally once they enter the aquatic system. Their high persistency in natural environment poses a potential health hazard to all form of life. Hence, there is a need for alternative d...

α-Galactosidase production by the fungal strains Penicillium chrysogenum LN33 and Aspergillus niger M47 cultivated in shaking and stationary conditions using soya meal extract as nutrient medium was investigated. Submerged shake flask fermentation was preferred over stationary cultivation for P. chrysogenum LN33 as it gave a high α-galactosidase yield (4200U/l). Because of pellet formation the ...

antitumor and antifungal agents. Recently, curacin A, which is a potential antitumor agent, was isolated from marine cyanobacterium (blue-green alga) Lyngbya majuscula as an antimitotic cytotoxic component.1} We have reported an effective assay method for antimitotic substances, which observes deformations of mycelia germinated from conidia of Pyricularia oryzae P-2b, and certain antimitotic co...

Claviceps fusiformis usually produces a stable viscous glucan during submerged culture fermentations. A new strain 139/2/1 G of the fungus, which subsequently autolysed this glucan to glucose, was studied and the autolysis ascribed to a constitutive PI -+ 3 glucanase and a P-glucosidase which were detected as soon as the fungal hyphae differentiated to a sclerotial form. The glucanase productio...

Corynebacterium glutamicum is an industrially important microorganism used for amino acids production. The present work describes the production of L-lysine from Corynebacterium glutamicum IIB-C9 through submerged fermentation process. Fifteen fermentation media were screened in this study for L-lysine production. Out of these fifteen media, FM:13 was found a best one for maximum production of ...

The decolouration of fermentation residues (vinasse) and liquid extract of coffee pulp by the mushroom Pleurotus ostreatus was studied in addition to laccase activity. The fungus was inhibited in both residues when they remained undiluted. In submerged cultivation on wastewaters a good production of biomass (14.8 g/l for vinasse and 5.4 g/l for extract of coffee pulp) and also laccase activity ...

Production of extracellular α-amylase enzyme by a filamentous fungus, Alternaria tenuissima was studied in solid-state fermentation (SSF) as well as submerged fermentation (SmF). The potential strain was successfully mutated by UV and ethyl methanesulfonate (EMS). High-level of α-amylase activity was obtained by the mutant At-Ch-5.6 (76.75 Units mL) after chemical treatment followed by UV mutan...
