Abstract:
The biomass of Fusarium solani (Mart.) Sacc. can effectively sorb lead from a solution of lead nitrate maximally within 5 seconds. Alkali treatment of mycelial biomass shows only a marginal increase in metal binding capacity, while homogenisation of mycelium results in an increase in sorption of lead and the biomass can be effectively regenerated by treating with 0.1M CaCl2 and MgSO4 solution, for recycling of the mycelia. Storage of mycelia is not deleterious to leal sorption; mycelia stored for a week can be effectively used for sorption of lead even after 5 cycles of regeneration tested.
