摘要:
Thermophilic obligately autotrophic H2‐oxidizing bacteria from Icelandic hot springs were tested for growth on thiosulfate. Ten strains were tested and all grew on thiosulfate but not on sulfite or sulfur. The product of thiosulfate oxidation was sulfate. The growth rate on thiosulfate was slower (μ=0.12 h‐1) than on H2(μ=0.34 h‐1). Washed cells which had been grown on thiosulfate could oxidize thiosulfate rapidly but H2‐grown cells oxidized thiosulfate much more slowly and with about a 3 h lag time. The bacteria would not grow on agar medium under H2but grew on agar medium containing th

摘要:
A quantitative screening procedure for biotin and biotin vitamer production was conducted on 129 yeast strains able to grow in a biotin‐free medium. Production of biotin and biotin vitamers varied considerably from strain to strain even within a species. The best producers of biotin were strains ofSporobolomyces roseus and Rhodotorula rubra whilst strains of Rhodotorula rubra and Yarrowia lipolyticaproduced the largest amounts of vitamer

摘要:
The production of pectin lyase (PL) was dependent on medium pH with two peaks of production, at pH 61 and 7‐2, that at pH 61 showing considerably higher activity. Crude PL activity was stable for at least 3 h at both 30 and 40d̀C. At 50d̀C there was a 20%, reduction in activity after 1 h; at 60d̀C there was a 40% reduction after 30 min yet>50% activity was retained for a further 2 h. The crude enzyme exhibited macerating ability against carrot tissue commensurate with that of a currently available commercial pectinase en

摘要:
Of the 11Fusariumspecies investigated, eight species were able to grow on tannin‐sucrose agar, whereas three species were unable to grow on this medium. The difference in growth response proved to be an additional character usable for identification ofFusariumspecie
