“…An adaptation of the U.V. sensitivity technique of McMeekin (1977) was used to distinguish between strains with possible low and high DNA base composition. Flauobacterium lutescens ATCC 253 I 1 and F. deuorans NCIB 8 195 (65 and 69 rnol C + C respectively; Holmes & Owen 1979) were used as high rnol u/ u G + C strains.…”

Phenotypic data on 203 Gram-negative non-fermentative bacteria of the Flavobacterium-Cytophaga group isolated from milk and butter were analyzed by numerical taxonomic techniques. Twenty reference strains including species of Flavobacterium, Cytophaga and strains of Pseudomonas paucimobilis were included in the study. Using the matching coefficient of Sokal & Michener with antibiotic susceptibility data included, 189 isolates were recovered in nine clusters. Six of these clusters were linked at or above the 85% S level while three were linked at or above the 79% S level. The largest cluster, representing 46.3% of the isolates, could be equated with Flavobacterium sp. Group IIb. Other clusters could be equated with Flavobacterium sp. L 16/1 (22.7% of isolates), F. balustinum (10.8% of isolates), F. breve (4.4%), F. multivorum (3.5%) and Cytophaga johnsonae (1.5%). The cluster resembling Flavobacterium sp. L 16/1 and a smaller unclassified cluster, were exceptional in being susceptible to the antibiotics cephalothin and penicillin G.

Enhanced Degradation of the Fungicide Vinclozolin: Isolation and Characterisation of a Responsible Organism

Enhanced degradation of the fungicide vinclozolin was stimulated by multiple successive applications to a soil without any history of previous pesticide input. A vinclozolin-degrading bacterium isolated from this soil was identified as a strain of Pseudomonas putida. This organism metabolised vinclozolin as a source of carbon, but it would neither grow with nor transform any other closely related dicarboximide fungicides nor the degradation product, 3,5-DCA. The degradation of vinclozolin by cultures of P. putida St-1 was investigated under various culture conditions; biodegradation was optimal at 23"C, pH 6-5 and inoculum densities of lo7 cells ml-' but cultures would grow from as little as 100 cells ml-l. Amendments of the vinclozolin-degrading isolate to soil previously untreated with the fungicide caused rapid degradation of applied vinclozolin, whereas amendments of boiled cells, or viable cells grown in the absence of vinclozolin, produced no discernible effect on the rate of vinclozolin degradation.

A bacterium capable of using the carbamate insecticide carbofuran as a sole source of carbon and energy, was isolated from soil. The ability to catabolise carbofuran phenol, produced by cleavage of the carbamate ester linkage of the insecticide, was lost at very high frequency when the bacterium was grown in the absence of carbofuran. Plasmid analyses together with curing and mating experiments indicated that the presence of a large plasmid (pIH3, greater than 199 kb) was required for the degradation of carbofuran phenol.
