Isolation and characterization of a phage active against streptomyces griseus

Studies on Streptomyces phage. I. Growth characteristics of the Streptomyces griseus host-phage system.

Within recent years, phages capable of infecting various Streptomyces species have been reported (Saudek and Colingsworth, 1947; Reilly et al., 1947; Koerber et al., 1950; Perlman et al., 1951; and Alexander and McCoy, 1956). Hoehn (1949) and subsequently Gilmour and Buthala (1950) demonstrated that streptomyces phage is indigenous to soil, the natural habitat of the host. The streptomyces host...

Isolation and characterization of a novel phage lysin active against Paenibacillus larvae, a honeybee pathogen

Paenibacillus larvae is the causative agent of American foulbrood (AFB) disease which affects early larval stages during honeybee development. Due to its virulence, transmissibility, capacity to develop antibiotic resistance, and the inherent resilience of its endospores, Paenibacillus larvae is extremely difficult to eradicate from infected hives which often must be burned. AFB contributes to ...

Characteristics of Streptomyces griseus strains resistant to phage.

In 1947 phage for Streptomyces griseus appeared in several commercial fermentations (Reilly, Harris and Waksman, 1947; Saudek and Colingsworth, 1947; Smith, Kiuhn, and Miesel, 1947; Woodruff, Nunheimer, and Lee, 1947). There has never been an outbreak of phage at this laboratory although a number of workers have been studying the growth of S. griseu or developing new strains. Nevertheless, in 1...

New antibiotics 4181-A and B from Streptomyces griseus; taxonomy, fermentation, isolation and characterization.

The new antibiotics 4181-A and B were isolated from the fermentation broth of Streptomyces griseus, a soil isolate. Their molecular formulae were determined as C29H21NO9 and C28H19NO9, respectively. The UV, IR and NMR spectra suggest that they possess a quinone moiety in their structures. They were found to have antibacterial, antifungal and antitumor activity.

synthesis and characterization of potentially biological active cyclometallated organoplatinum(ii) complexes

this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
