STUDIES ON ANTIBIOTIC 230 AS A MOLLUSCICIDE

Studies on a new pigment antibiotic, chrothiomycin.

Ghrothiomycin inhibits reactions of tyrosine hydroxylase1} and dopamine /?-hydroxylase2>3). It also exhibits weak antibacterial activities. It is obtained as blackish purple crystals containing sulfur and named chrothiomycin. In this paper, characters of chrothiomycin-producing Streptomyces are described together with the chemical and physical properties of the antibiotic and some of the biolog...

Studies on a new herbicidal antibiotic, homoalanosine.

Homoalanosine having a herbicidal activity was isolated from the culture filtrate of a soil isolate SC-1688 which was classified as Streptomyces galilaeus. The chemical structure of homoalanosine was determined to be L-2-amino-4-nitrosohydroxyaminobutyric acid by analyses of spectral and biological data. The antibiotic has high herbicidal activity at low concentrations against especially common...

Recent studies on albomycin, a new antibiotic.

Biosynthetic studies on antibiotic A47934.

A47934, a peptide antibiotic produced by Streptomyces toyocaensis, belongs to the glycopeptide class of compounds which includes ristocetin and vancomycin. Incorporation studies with radioisotope-labeled substrates indicated that tyrosine, p-hydroxyphenylglycine, p-hydroxyphenylglyoxylate, acetate, and sulfate were efficiently incorporated into A47934. This is consistent with the reported biosy...

Effects of molluscicide baits on field populations of house mice

Two trials were carried out to test the effects of field applications of snail baits on populations of house mice (Mus domesticus) inhabiting cereal-cropping fields during a mouse plague in South Australia. In the first trial, grain based pellets containing 2% w/w active ingredient methiocarb, were laid in trails across fields before crops were sown. The second tested the effect of whole wheat ...
