Surface tension activity and paramorphogenic effect of sorbose, sodium desoxycholate, and griseofulvin on the growth of colonies of Chaetomium aureum Chivers.

Sorbose at 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1.0% levels, sodium-desoxycholate at 0.025, 0.050, 0.075, 0.1 and 0.125% levels, and griseofulvin at 0.001, 0.002, 0.003, 0.004, 0.005, 0.006, 0.007, 0.008, 0.009, and 0.010% levels restrict the growth of colonies of Chaetomium aureum, both at pH 6.5 and 7.0. Restriction of colonies was most effective with 0.7% sorbose, 0.1% sodium-desoxycholate, and 0.006% griseofulvin in the medium adjusted to pH 6.5. Surface tension activity of sorbose, sodium-desoxycholate, and griseofulvin in different concentrations was determined, following the usual standard method.
