GERMINATION OF CONCENTRATED SUSPENSIONS OF SPORES FROM

Javier Barrios-González

Open publisher page 0 citations

Abstract

SUMMARY Germination of condiospores from A.niger in very concentrated suspension was required to inoculate solid fermentation media, but a germination self-inhibitor was detected in spores. It was found that the inhibitory effect depended on the composition of the medium and was reduced when glucose was used as a carbon source. The effect of the .self-inhibitor was eliminated by washing the spores and using glucose and a protein nitrogen source in the germination medium. By this method it was possible to increase about 100 times (106 to 108 ) spore concentration, keeping more than 90% germination.
