Growth enhancement and selection attempts for Spirillum volutans
… quantification for growth or survival of Spirillum volutans; and to develop an improved method for selection of S. volutans from nature. Growth enhancement studies began with casein hydrolysate-succinate-salts medium (CHSS). Casein hydrolysate concentration, type of casein hydrolysate, pH, …

A Study of Peroxide Resistance in the Microaerophile, Spirillum volutans
… of adaptive responses of the microaerophile Spirillum volutans to various stresses such as heat and peroxide shock have been hampered by an inability to obtain reliable colony counts of the organism by the spread plate method. Colony counts approaching direct microscopic counts (DMCs) were …

A taxonomic study of the genus Spirillum ehrenberg, with special reference to nutrition and carbohydrate catabolism
… urease production; NaCl tolerance of fresh-water Spirillum strains; effects of calcium ions on growth of Spirillum strains; production of fluorescent pigments; enzyme assays of key enzymes of carbohydrate catabolism in P. lunatum, A. itersonii, and A. peregrinum; and the effects of various …

A morphological and physiological classification of Spirilla
… 20 marine and fresh-water species of the genus Spirillum, plus additional strains of S. gracile, S. itersonii, S. serpens, and S. volutans, and 6 un-named strains of spirilla, were subjected to over 90 physiological tests and also various morphological tests using standardized inocula, media, …

Development of defined media for motility and for growth of Spirillum volutans, with special reference to biological monitoring of pollutants and to obligate microaerophilism of bacteria
… was a possible application of the motility of Spirillum volutans to detection of pollutants in industrial effluent for the purpose of in-plant biological monitoring. The other was a nutritional study of the organism with emphasis on its obligate microaerophilism. In the pollution monitoring …

A taxonomic study of the Spirillum lipoferum group, with descriptions of a new genus, Azospirillum gen. nov., and two species, Azospirillum lipoferum (Beijerinck) comb. nov. and Azospirillum brasilense sp. nov.
… strains of the root-associated nitrogen fixer <u>Spirillum lipoferum</u> exhibited a similar morphology (slightly-curved to S-shaped cells having a cell diameter of 1.0 μm) and had a DNA base composition of 69 - 71 mol% G + C (Tm). When grown in broth the cells had a single polar flagellum, but …

The Effect of Natural Organic Matter on UV/H<sub>2</sub>O<sub>2</sub> Treatment and the Effect of UV/H<sub>2</sub>O<sub>2</sub> Treatment on Natural Organic Matter
… by MP and LP processes were similar. The <i>Spirillum</i> strain AOC increased through UV/H<sub>2</sub>O<sub>2</sub> 50 to 65% due to formation of smaller more soluble compounds, e.g., organic acids. <i>Pseudomonas fluorescens</i> strain AOC concentration increased when CONV water served as …
