✦ Synopsis

The germination of spores of microorganisms has been studied in detail with reference to bacterial spores (HALvo~so~ and CgvRcI~ 1957). I n f o r m a t i o n regarding the germination of mold spores is, however, incomplete. U n d e r certain conditions, the germination of mold spores is k n o w n to be induced.

The investigations of SgEA~ and DODGE (1927), GODDAMn (1935, 1939) and GODDARD and SMITH (1938) established that heat treatment of the ascospores of Neurospora resulted in activation. There was a large increase in respiration (GOD-DARD 1935), and latent carboxylase was believed to be activated (GODDARD and S~IT~ 1938). Apart from heat treatment, GODDARD (1938) showed that acetaldehyde and ethanol were able to induce a large increase in QO 2 of dormant spores of Neurospora, but that this increase was of short duration and these substances did not help in germination. The activation of Neurospora spores can also be brought about by certain other chemicals, such as furfural (EMERSON 1948; :u FJORD and CAMPBELL 1951; SUSS~ACV 1954) and some of its heterocyclic derivatives (Suss~AN 1953). TE~UI and Moc~IzvKI (1955) have shown that glucose and phosphate promote respiration in spores of Aspergillus oryzae.

YANAGITA (1957) made a detailed study of certain biochemical aspects of the

The most important means of elucidating the pathway(s) of metabolism is, probably, the actual identification of all the enzymes involved in the postulated pathway. As far as the authors are aware, there has been no systematic attempt to elucidate the metabolic pathways in spores of fungi, although c

## Abstract Inhibition of radial growth and spore germination of __Aspergillus niger__ in media with added chitosan were detected. The highest radial growth inhibition (73%) was determined at 24 h with 3 g · L^βˆ’1^ of chitosan, and the percent inhibition of spore germination was 40% after 13 h of in
