The microorganisms like fungi proliferate in different environmental and ecological conditions depending upon theavailability of nutrients and the form of nutrient that they absorb. In addition to this the physical conditions liketemperature, pH, salinity and light etc. also effect the growth and biomass production of fungal species. The presentstudy was carried out to determine the effect of variation in physical and chemical parameters on growth and biomassproduction of the fungal strain Fusarium equiseti (MTCC9658). A maximum biomass yield of 12.24 g/L at pH 5 andtemperature of 30ºC was recorded; and minimum of 5.21 g/L at pH 9 and temperature of 25ºC.The observations clearlyindicate that pH 9 and above did not support higher biomass production at any of the temperatures,while pH 5 to pH 6supports higher dry biomass production in all temperature ranges applied.The different carbon and nitrogen sourcesused in the medium corresponded to variation in growth of the strain. Dextrose in combination with Yeast extract asnitrogen source was best for biomass production.
