Physiological Studies on Rhizobium

Physiological Studies on Rhizobium: IV. Utilization of Carbonaceous Materials.

Some studies on the groundnut Rhizobium symbiosis.

ltesults of inoculation experiments with an efficient strain of Rhizobium (eB 756) indicated that indigenous strains occupied most of the nodules of groundnut, grown in high Rhizobiullt gl"Oundnul populatell soils. These could he overcome hy using high rate of inoculation containiug trace clements, molyhdenum and horon, at 1.6 ppm and 4 ppm, respectively, wilh higher rates of phosphate applicat...

Physiological Studies on Trichomonas Vaginalis

Although many investigations into Trichomonas vaginalis Donne 1875 and vaginal trichomoniasis have been made since the organism was recognized again as a pathological entity by Hohne in 1916, problems on its pathogenicity, epidemiology and therapeutics are still left in confusion. One of the main reasons of this confusion appears that the bacteria free cultivation of this organism has not been ...

Physiological Studies on Candida albicans

Candida albicans is a polymorphic fungus that is capable of causing the life-threatening disease Candidiasis once it reaches the bloodstream of a susceptible host. One of the major virulence factors is its ability to switch from yeast to hyphal or pseudohyphal morphology. Yeast to hyphal transition is well studied and many environmental signals such as high temperature, alkaline pH, and presenc...

Studies on the Aspartic Acid Decarboxylase of Rhizobium Trifolii.

Virtanen and Laine (1937) were the first to suggest the existence of an aspartic acid decarboxylase in Rhizobium trifolii, by the isolation of beta-alanine from a 47-day fermentation mash containing aspartic acid. Shive and Macow (1946), working with hydroxyaspartic acid as a competitive analogue for aspartic acid in the metabolism of Escherichia coli, found that the addition of this compound t...
