Aims: Determination of the age of the mycelial inoculum is essential for the large-scale enzyme production. For smallscale cultivations of fungi, spore inoculum is generally used. Use of spore inoculum becomes difficult when large-scale cultivations

The ambient temperature is a drawback in industrial ethanol production in Jaffna due to heat killing of yeast during fermentation. Thus a search was initiated for thermotolerant organisms suitable for fermentation in hot climates. The screening of th

Citric acid produced by Aspergillus niger was increased from 4.6g l-1 to 7.8gl-1 by supplementing basal medium with methanol (30mll-1). While stimulating citric acid production, methanol did not improve membrane permeability of the fungus for citric

Integration of bioconversion and the first step(s) of down stream processing can be used as a means to increase the productivity of bioprocesses. This integration also gives the possibility to run the bioconversion in a continuous mode. We demonstrat
