Screening of Some Basidiomycetes for Bio-polymers and Biomass Production in Submerged Cultivation

Abstract

Twenty-one species of edible and non-edible basidiomycetes were screened for bio-polymers and biomass production in submerged cultivation. All the basidiomycetes produced bio-polymers and there was variation in quantities of bio-polymers produced by the strains at different incubation times. The bio-polymers production ranged within 44 - 9,177 mg/l, 63 - 14,525 mg/l and 69 - 6,367 mg/l at days 2, 7 and 14, respectively. Coriolus versicolor produced the highest yield at day 7. The biomass production at days 2, 7 and 14 ranged within 0.12 - 0.23g dry w/l, 0.13 - 0.25g dry w/l and 0.13 - 0.30g dry w/l in which C. versicolor also had the highest yield. The highest biomass production was recorded on day 14.
