Water relations of some Penicillium species at 25 °C

The water relations of one isolate of each of 26 Penicillium species was studied at 25 °C. Eight isolates were grown on media with water activity (aw) controlled by NaCl, glycerol or a glucose/fructose mixture. As the differences in effects caused by the various solutes were slight, the other eighteen were grown on glycerol based media only. Minimum water activities permitting germination differed widely, from 0.90 for P. digitatum (Pers. ex Fr.) Sacc. and P. funiculosum Thorn to 0.78 for P. brevicompactum Dierckx, P. implicatum Biourge, P. janczewskii Zaleski and P. phoeniceum van Beyma. Data on the influence of water activity on radial growth are also provided.
