An Antiviral Substance from Penicillium Funiculosum
1. Helenine prevents the establishment in mice of passive viral immunity by anti-Semliki serum of swine, rabbit, or guinea pig origin. 2. A period of 12 days must elapse, between the antiviral serum administration and challenge with virus, for prevention of the establishment of passive immunity to become apparent. This period is believed to correspond to that in which injected antibody persists...
متن کاملThe isolation, purification and properties of the cellobiohydrolase component of Penicillium funiculosum cellulase.
1. A cellobiohydrolase component was isolated from a Penicillium funiculosum cellulase preparation by chromatography on DEAE-Sephadex, and purified by isoelectric focusing. 2. Purified in this way, the enzyme was homogeneous as judged by electrophoresis on sodium dodecyl sulphate/polyacrylamide gels and isoelectric focusing in polyacrylamide gels. 3. Acting in isolation, the enzyme had little h...
متن کاملProperties of selected hemicellulases of a multi-enzymatic system from Penicillium funiculosum.
A multi-enzymatic system from Penicillium funiculosum displayed alpha-L-arabinofuranosidase, endo-1,4-beta-D-xylanase, beta-D-xylosidase and endo-1,3-1,4-beta-D-glucanase activities at high levels over a wide acidic pH range of 2.0 to 5.5. Moreover, the pH stability was particularly extended over the wide range of pH of 2.0 to 8.0 with endo-1,3-1,4-beta-D-glucanase and endo-1,4-beta-D-xylanase;...

متن کاملSQ 30,957, a new antibiotic produced by Penicillium funiculosum. Taxonomy, fermentation, isolation, structure determination, synthesis and antibacterial activity.
A new antibiotic, SQ 30,957, 4-diazo-3-methoxy-2,5-cyclohexadien-1-one, has been isolated from fermentation broths of Penicillium funiculosum. The structure (1) was deduced from its spectroscopic properties and its degradation reaction. SQ 30,957 has excellent activity against anaerobic bacteria such as Clostridium and Bacteroides and has moderate activity against aerobic bacteria. The compound...
