properties of a beta-(1-4)-glucan hydrolase from aspergillus niger. | 1. a beta-(1-->4)-glucan hydrolase prepared from aspergillus niger, as described by clarke & stone (1965a), showed a ph optimum in the range 4.5-6 and k(m) 0.25% when acting on a cellulose dextrin sulphate substrate. 2. the hydrolase rapidly decreased the specific viscosity of carboxymethylcellulose with a small increase in the production of reducing sugars. the identity of the products of hydrolysis of cellotetraose, cellopentaose and their reduced analogues indicate a preferential cleavage of ... | 1965 | 5862418 |
production of the enzyme naringinase by aspergillus niger. | the formation of naringinase, a glycolytic enzyme produced by aspergillus niger, is repressed by glucose. production of the enzyme is decreased below ph 4.0 and is stimulated by the presence of substrate. fermentation conditions are described which cause the formation of the enzyme in approximately a fivefold greater concentration than that previously described. | 1965 | 5866035 |

nonessentiality of boron in fungi and the nature of its toxicity. | an investigation was undertaken to determine whether any of the following fungi had a requirement for boron (b): saccharomyces cerevisiae, aspergillus niger, neurospora crassa, and penicillium chrysogenum. boron was unessential, and hence a study was made of the concentrations of b that reduced the growth of s. cerevisiae and p. chrysogenum and the mode of action of the b toxicity. fifty and 4000 mg b/liter, respectively, significantly (5% level) reduced the growth of the latter 2 species.in bot ... | 1966 | 16656256 |
