Allomyces macrogynus can synthesize methionine using sulphide, cysteine, cystathionine,
homocysteine or thioacetamide as sulphur sources. With thioacetamide, methionine …

A mutant unable to grow under acidic conditions was isolated from the acidophilic
heterotrophic bacterium Acidiphilium facilis 24R. The growth of the mutant could be fully …

Ornithine decarboxylase (ODC) from Mucor bacilliformis and Mucor rouxii was studied.
Enzymatic activity was maximal at pH 7.2–7.4 and at 30° C. The K m was 0.17 mM for the M …

The naturally occurring polyamines putrescine (NH*-(CH&-NH& spermidine (NH&CH&-NH-

Bacillus alcalophilus, an obligately alkalophilic bacterium that grows at pH 11.0, has an
intracellular pH of 9.5 or less. Unlike all other living organisms, polyamines (putrescine …

The involvement of polyamines (PAs) in the interaction between Pinus sylvestris L.
seedlings and an ectomycorrhizal fungus Suillus variegatus (Swatz: Fr.) O. Kunze was …

The intracellular level of S-adenosylmethionine increased as the yeast-phase cells of Mucor
racemosus were induced to convert to hyphae. This increase correlated well with time …

Growth and soluble protein contents of these fungi decreased with increasing concn of O.
sanctum extracts, an effect similar to that of the polyamine biosynthesis inhibitor, smallcap˜ D …

Recently, we found that a new type of polyamine oxidase was widely distributed in fungi. 1)
In a preceding paper, 2) the enzyme from Penicillium chrysogenum was crystallized and …

Monascus purpureus Went grew better in glucose-peptone-yeast extract broth than in any
other natural medium tried, and did not grow nearly so well in a Czapek-Dox mineral-salts …
