Fourteen strains of Grifola frondosa (Dicks.) S. F. Gray, originating from different regions (Asia, Europe and North America) were tested for lignin degradation, ligninolytic enzyme activities, protein accumulation and exopolysaccharide production during 55 days of cultivation on oak sawdust. Lignin degradation varied from 2.6 to7.1 % of dry weight of the oak sawdust substrate among tested stra...

We have found a novel prolyl aminopeptidase in Grifola frondosa. The enzyme was purified by DEAE-Sepharose CL-6B, Butyl-Toyopearl, Sephacryl S-100, and Mono-Q column chromatographies. The purified enzyme exists as a dimer and gives high activity toward L-proline-p-nitroanilide. The enzyme was strongly inhibited by p-chloromercuribenzoic acid and iodoacetic acid and markedly inhibited by phenylm...

Hyaluronans (HAs) are glycosaminoglycans produced in the bodies of Anguilliform and Elopiform leptocephali, and play a role in metabolic energy. In mammals, HA synthesis-promoting substances (HASPS) up-regulate the expression of HA synthase (HAS) and increase the amount of HA in the body. In this study, Japanese eel leptocephali were fed a HASPS containing diet. We analyzed HAS1s and HAS2 expre...
