Abstract
PreculturedPenicillium biomass can accumulate U from solutions of uranyl chloride. A 4 g (fresh weight) fungal mass will remove, over a 1 to 4 h period, between 20 and 30 °C, 75 to 90% of the UO2-ion from 1 to 10 ppm solutions. Accumulation is more or less the same between pH 5.5 to 7.5, and retains over 2/3 of its efficiency at pH 2.5. Boiling, pasteurization and trichloracetic acid pretreatment do not reduce and may increase fungal efficiency. Preculture with Tween 80 improves efficiency by its effect on formation of small beaded mycelial masses.
