S ummary : Heat resistant moulds of the genera Byssochlamys, Aspergillus, Penicillium and Paecilomyces can be cultivated selectively in the presence of Bacillus spp. when at least 10 p/m of chloramphenicol or chlortetracycline is added to the growth medium. The inhibitory agents sulphafurazole, penicillin, streptomycin, oxytetracycline and furazolidone, do not give completely selective and optimal growth of these moulds. Selective cultivation of heat resistant moulds from 200 samples of Dutch soil showed that Byssochlamys nivea occurs more frequently than was expected, whereas Byss. fulva occurs by way of exception. Other heat resistant moulds observed in soil are, in order of frequency, species of the genera Aspergillus, Paecilomyces and Penicillium .
