Procedures to enhance heat resistance of Rhizobium
Means were sought to enhance the heat resistance of a strain of Rhizobium leguminosarum biovar phaseoli that died rapidly in soil at 43°C. Bacteria were more resistant to high temperatures in soil than broth o...

Effect of a non-ionic surfactant added to the soil surface on the biodegradation of aromatic hydrocarbons within the soil
A study was conducted to determine whether a non-ionic surfactant (Novel II 1412-56) added to the surface of Lima silt loam would enhance the biodegradation of phenanthrene and biphenyl present within the soil...

Selecting inocula for the biodegradation of organic compounds at low concentrations
The inability of many organisms to degrade pollutants at low concentrations is a problem when selecting inocula for bioremediation of sites with these low concentrations. Thus, a study was conducted to determi...

Factors affecting the microbial degradation of phenanthrene in soil
Because phenanthrene was mineralized more slowly in soils than in liquid media, a study was conducted to determine the environmental factors that may account for the slow biodegradation in soil. Mineralization...

Factors affecting co-inoculation with antibiotic-producing bacteria to enhance rhizobial colonization and nodulation
Co-inoculation with antibiotic-producing bacteria and rhizobia resistant to those antibiotics has been proposed as a means of promoting colonization and nodulation of legumes by root-nodule bacteria. A study w...

Explanation for the decline of bacteria introduced into lake water
The sizes of the populations of individual bacterial species diminished following their addition to water from lakes with different trophic levels at temperatures of 5, 10, 15, and 30°C. Some species persisted...

Populations and activity of carbofuran-degrading microorganisms in soil
Kendaia clay loam contained more than 105 microbial cells per g able to convert 14C-carbonyl-labelled carbofuran (2,3-dihydro-2,2-dimethylbenzofuran-7-yl methylcarbamate) to 14CO2 but never more than 130 cells pe...

Effect of organic amendments on bacterial multiplication in lake water
In Cayuga Lake water amended with 30 μg of glucose or amino acids per ml, an added strain of Pseudomonas fluorescens and indigenous bacteria grew extensively, Pseudomonas sp. B4 and two rhizobia multiplied at a m...

Factors involved in multiplication and survival ofEscherichia coli in lake water
The population of a strain ofEscherichia coli that was resistant to nalidixic acid and streptomycin declined rapidly in samples of sterile and nonsterile Cayuga Lake water and reached an undetectable level in non...

Factors affecting the survival and growth of bacteria introduced into lake water
The populations of Pseudomonas sp. B4, Escherichia coli, Klebsiella pneumoniae, Micrococcus flavus, and Rhizobium leguminosarum biovar phaseoli declined rapidly in lake water. The initially rapid decline of the t...

Co-inoculation with antibiotic-producing bacteria to increase colonization and nodulation by rhizobia
A study was conducted to determine whether colonization of legume roots and nodulation byRhizobium meliloti andBradyrhizobium japonicum could be enhanced by using inocula containing microorganisms that produce an...

Colonization and mineralization of palmitic acid byPseudomonas pseudoflava
Pseudomonas pseudoflava and palmitic acid were used to investigate the role of bacterial colonization in the degradation of waterinsoluble organic compounds. Mineralization was measured by trap** the14CO2 prod...

Absence of a role for lytic microorganisms in the decline of bacteria andSaccharomyces introduced into soil
The populations ofKlebsieila pneumoniae, Escherichia coli, Enterobacter aerogenes, andPseudomonas sp. fell following their addition to soil, but species lysing these gram-negative bacteria were not detected. The ...

Effects of low pH and high Al, Mn and Fe levels on the survival ofRhizobium trifolii and the nodulation of subterranean clover
The effects onRhizobium trifolii and the nodulation of subterranean clover of possible inhibitors associated with soil acidity were evaluated. In an inorganic salts solution in the presence of subterranean clover...

Effect of the quantity and duration of application of simulated acid precipitation on nitrogen mineralization and nitrification in a forest soil
A study was conducted of the influence of the rate of application of simulated acid rain on N mineralization and nitrification in a forest soil. The rates were varied by applying different quantities of simula...
