Abstract:: Bdellovibrio bacteriovorus is a small parasitic bacterium present in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative bacteria, an important role in soil ecology has been suggested for this organism. A study of effects of herbicides upon Bdellovibrio might consequently be of considerable value. In this 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...

Creator:: Rothman, Stanley
Abstract:: For the past six years a bacterial infection has been the cause of large losses of adult, spawning, American shad (Alosa sapidissima) in the Coos, Millicoma and Smith Rivers of Oregon. There was a sizable commercial fishery for shad in these rivers and losses of fish due to this infection...

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...

Creator:: Carlson, René Virginia
Abstract:: 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...

Creator:: Wullstein, L. H. (Leroy H.)
Abstract:: Prevailing concepts relating to the non-enzymatic gaseous loss of nitrite from soil are thought to be inadequate as regards to the mechanisms involved. The conventional explanation for nitric oxide formation i.e., the acid decomposition of nitrite, is held to be insufficient in substrates of only mild or slight acidity. A...

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...

Creator:: Washam, Clinton Jay
Abstract:: Pseudomonas aeruginosa cells were selected for their ability to grow in the presence of 750 ppm alkyldimethylethylbenzyl ammonium chloride (QAC). These cells were found to retain their resistance to the germicide throughout tri-weekly transfers for 7 months in tryptone glucose yeast extract (TGY) broth containing no QAC. Comparisons of the...
