An enzyme capable of cleaving catechin was present in the mycelium ofCheatomium cupreum. Maximum synthesis of the enzyme occurred after 15 days growth. Sucrose and maltose increased enzyme synthesis among the carbon sources tested. Catechol, protocatechuic acid and phloroglucinol carboxylic acid were the intermediates of catechin degradation.Cheatomium cupreum containedmeta-cleaving enzymes for catechol and protocatechuic acid metabolism. Pyruvate was identified as an end-product. Catechin…

TLDR
Dl-mandelate elicits immediate synthesis at a steady rate of the first two enzymes of the pathway, but two enzymes which act below the level of benzoate are synthesized only after a considerable lag, and Succinate and asparagine do not significantly repress the synthesis of the enzymes responsible for mandelate oxidation.

TLDR
Experiments with the blocked mutants showed that benzoylformate, the third intermediate of the pathway, acts as an inducer without prior conversion to mandelate, and that there is no inducible, concentrating permease forMandelate.

TLDR
Oxalic and glycolic acids increased slowly throughout the growth period, and more total organic acid was produced on the glucose medium than on the mannitol medium, while the pH of culture filtrates increased.
