Comparison of Aspergillus niger spore production on Potato Dextrose Agar (PDA) and crushed corncob medium.
Minimizing the number of generations through which a culture passes from the initial culture until its recovery at the fi nal stage of fermentation is a general principle. For fi lamentous fungi, a large number of generations can cause the appearance of low-yield producing variants and mutant strains, which are generally genetically unstable. The use of successive sub-cultures can decrease the ...
متن کاملModulation of water activity on fungicide effect on Aspergillus niger growth in Sabouraud dextrose agar medium*.
AIMS To examine whether water activity (aw) in combination with low concentration of fungicides can be used to effectively control Aspergillus niger van Tieghem growth in cultural medium, the Sabouraud dextrose agar (SDA). The data would be used as baseline information for reducing A. niger contamination in insect artificial diets. METHODS AND RESULTS Aspergillus niger was isolated from an in...
متن کاملProduction and Evaluation of Chitosan from Aspergillus Niger MTCC Strains
Three different Aspergillus Niger MTCC strains (872, 1785 and 2208) were used for the production of chitosan. Multivariate growth mediums in varying incubation periods were analyzed for the production. The produced chitosan was characterized by its physical appearance, moisture content (by means of gravimetric method), percentage of ash and solubility (through the Association of Official Agricu...

متن کاملComparison of inhibitory mold agar to Sabouraud dextrose agar as a primary medium for isolation of fungi.
Clinical specimens cultured on two selective fungal media, inhibitory mold agar (IMA) and Sabouraud dextrose agar (SDA), were compared with respect to recovery of fungi. Of the 840 fungal isolates recovered, 69.3% grew on both IMA and SDA; 24.9% grew only on IMA; and 5.8% grew only on SDA, showing that IMA is superior (P=0.003).
