inhibition and agglutination of arthrobacters by psuedomonads.the bacterial flora of water in narragansett bay, r.i., was observed semimonthly from 1962 to 1964. dominant isolates were keyed to genus, and the isolates for each genus were expressed as percentage of total isolates. there was a consistent inverse relationship between arthrobacters and the dominant pseudomonads. pseudomonad growth on agar plates markedly inhibited arthrobacter cross-streaks. agar from inhibition zones as well as supernatant fluids from pseudomonad broth cultures inhibited arth ...19676025306
numerical taxonomy of gram-positive and catalase-positive rods isolated from frozen vegetables.one hundred isolates from peas, beans, and corn were compared with cultures of corynebacterium, microbacterium, and arthrobacter by use of numerical taxonomic procedures. six groups (clusters), representing 75% of the isolates, resembled corynebacteriaceae. there was some doubt regarding the genera represented because the groups were not closely related to many of the known strains. the relationship of the different groups to each other, as well as a number of their properties, is presented.19676031430

alteration of glucose metabolism of arthrobacter crystallopoietes by compounds which induce sphere to rod morphogenesis.succinate and several other compounds which induce sphere to rod morphogenesis of a. crystallopoietes were found to suppress both catabolism and assimilation of glucose. diauxic growth patterns resulted from growth on glucose plus any one of these compounds. glutamate stimulated growth but was not an inducer of morphogenesis. with this compound, diauxic growth and suppression of glucose catabolism or assimilation did not occur. glucose permease was studied with alpha-methylglucoside as substrate ...19695773009
role of alcoholic intermediates in formation of isomeric ketones from n-hexadecane by a soil arthrobacter.a soil arthrobacter species isolated from an oregon soil was capable of transforming n-hexadecane to a series of ketonic products, the 2-,3-, and 4-hexadecanones, with evidence for accumulation of 2- and 3-hexadecanols as oxidative intermediates when yeast extract or peptone was used as a growth substrate. the accumulation and participation of internal alcohols in this type of hydrocarbon transformation has not been previously reported. in the absence of yeast extract or peptone, growth from low ...19695785950
