Abstract

Summary: Byssochlamys fulva asci are resistant to high concentrations of aqueous chlorine and iodophor solutions, but are sensitive to peracetic acid. Concentrations of 2% and 4% of peracetic acid gave 99·9% reductions in 2·5 and 1·3 min, respectively. The asci were also sensitive to methyl bromide gas (MeBr), c. 5 × 104 asci/g inoculated into tapioca starch powder (aw= 0·69) being killed in 30 days by 90 mg of MeBr/kg of starch. About 180 asci/g were killed by adding 60 mg of MeBr/kg of starch.
