      More Details Abstract Fulltext PDF

      The morphological, cultural and physiological characters of strains ofNocardia corallina andNocardia rubra isolated from coconut oil and the alimentary canal of the earthworm are described. Deeply staining granules in the cytoplasm pf theNocardia when grown on Ashby’s nitrogen-free. medium have been reported,N. corallina showed bipolar granules whileN. rubra showed subcentrally situated granules. The observations are substantiated with photomicrographic illustrations. The need for further study of the cytology and nutrition of theNocardia is emphasised.

      The isolation, cultural characteristics and the nutrition of an oxalatedecomposing micro-organism,Bacterium oxalaticum nov. sp., obtained from the intestine of Indian earthworms, are described and its taxonomical position discussed. Besides utilizing oxalate as a sole source of carbon the bacterium can utilize formate even better. Attention has been drawn to the fact that oxalate-decomposing bacteria occur in a family other than thePseudomonadaceæ—a. family which had hitherto yielded practically all the known oxalate-decomposing bacteria.

      More Details Abstract Fulltext PDF

      A detailed account of the morphological, staining, penicillin sensitivity and serological peculiarities of five strains of an oxalate-decomposing bacterium including the well-recognized strainVibrio extorquens, has been given. Inasmuch as all the strains share many of the characteristics of the genusArthrobacter and notVibrio the desirability of placing the bacterium in the former genus for the time being has been suggested. The possibility of the strains falling under an altogether new genus which represent a phylogenic link between the pseudomonads and diphtheroids has been speculated.
