  • Antagonistic properties of aquatic myxobacteria and pseudomonads

    Creator:
    Burnison, Bryan Kent
    Abstract:
    Certain species of the orders Myxobacterales and Pseudo-monadales are well-known antagonists. Pseudomonas fluorescens and Pseudomonas putida have been reported to produce bacteriostatic and bactericidal substances. Among the myxobacteria there are various species which are known for their ability to produce lytic enzymes and antibiotics. Organisms from both of these groups...

  • A taxonomic study on myxobacteria isolated from fish

    Creator:
    Porter, Sook Hee
    Abstract:
    While the genus Cytophaga has been defined and classified on a morphological basis, knowledge of fresh water members of this group of myxobacteria is scanty. In the present study cultural and morphological characteristics were investigated in an attempt to classify a group of fresh water cytophaga. Microscopic examination revealed all...

  • Fresh water myxobacteria : a taxonomic study

    Creator:
    Nitsos, Peggy Koerner
    Abstract:
    Myxobacteria are known to occur in the aquatic environment, however, little information is available regarding the taxonomy of these organisms. This investigation was initiated in an attempt to classify a group of fresh water cytophagas on the basis of biochemical and physiological as well as cultural and morphological characteristics. The...

  • Partial purification and properties of a columnaricin isolated from the myxobacterium Chondrococcus columnaris

    Creator:
    Needleman, David Sol
    Abstract:
    Of the 14 strains of Chondrococcus columnaris examined, 4 produced antagonistic substances that inhibited the growth of other strains of this species. The antagonistic substance produced by strain 3-P63-12 was examined in greater detail. Since the inhibitory substance had an extremely narrow spectrum of activity, and was not transmissible in...
