| penicillin acylase activity of penicillium chrysogenum. | the penicillin acylase activity of penicillium chrysogenum was studied. washed mycelial suspensions of a high penicillin-producing and a nonproducing strain were found to be similar in respect to relative acylase activity on benzylpenicillin, 2-pentenylpenicillin, heptylpenicillin, and phenoxymethylpenicillin. the relative rates for both strains, as determined by 6-aminopenicillanic acid formation, were approximately 1.0, 2.5, 3.5, and 6.0 on the penicillins in the order given. the high producin ... | 1965 | 5867654 |

| microbiology of saturated salt solutions and other harsh environments. ii. ribonucleotide dependency in the growth of a salt-habituated penicillium notatum in salt-free nutrient media. | a strain of penicillium notatum has been found growing upon media containing saturated calcium acetate which upon passage through media containing saturated kc1 loses its ability to grow at normal rates in salt-free glucose-peptone medium. this salt-habituated form can be restored to a near-normal growth rate by adding yeast extract, rna or rna-hydrolysates, but not by dna or its hydrolysate. the 4 rna nucleotides in combination replace yeast extract whereas riboside and base combinations do not ... | 1967 | 6040891 |

| [a statistical method for the determination of the yield correlation of antibiotic-producing microorganisms]. | the antibiotic yields of industrial selectants must be checked at several steps of cultivation. here the question arises whether the activities at the different levels of cultivation are correlated. the common coefficient of correlation cannot be used because repeated determinations of the yield at one selectant result in different values. in order to have only one fixed value per selectant we define the mean value around which the observed values are varying. but these mean values cannot be obs ... | 1984 | 6089455 |

| interferon induction and macrophage activation by a mycovirus double-stranded rna/tobramycin complex following treatment with human serum. | double-stranded rna (dsrna) molecules, generally effective inducers of interferon (ifn), have a weak potency in man apparently because of the presence of a serum rnaase which quickly inactivates extracellular dsrna. we have discovered that tobramycin, an aminoglycoside, protects penicillium chrysogenum mycovirus dsrna (pcmdsrna) from the degradative action of the nuclease. exposure of the dsrna/tobramycin complex to human serum results in some degradation, but still permits the production of sig ... | 1982 | 6183374 |
