Fish offal-peat compost extracts as fermentation substrate
AbstractHydrolysates of peat-fish offal compost were used as substrate sources for the growth of the acid-tolerant fungus Scytalidium acidophilum. This fungus has been previously grown on acid peat hydrolysates, and it was expected that higher concentrations of nutrients, such as nitrogen, in the fish offal-peat compost, would enhance the fungal growth. In shake-flask experiments, culture media based on the compost hydrolysates produced 2·5 g/litre of dry fungal biomass, which was not significantly different from the concentration obtained when diluted Sphagnum peat hydrolysate was employed at the substrate source. However, it was not necessary to dilute the compost hydrolysates, as is required with the peat hydrolysates, to facilitate the growth of S. acidophilum. The potential for the compost hydrolysate to support a higher microbial growth when it is supplemented with carbohydrates is discussed.
