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...
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...
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.
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...
Most studies of bacteria in water have concerned public health; little attention has been given to organisms which are indigenous to
the aquatic environment. Myxobacteria are known to occur in soil,
in the marine environment, and several have been studied in relation
to diseases of salmonid fishes. However, little information...
