Nitrogen Dioxide Fixation in Bacterial Chromatin Studies

Nitrogen dioxide fixation in bacterial chromatin studies.

Eller, Charles (St. John's University, Jamaica, N.Y.), and William H. Beckert. Nitrogen dioxide fixation in bacterial chromatin studies. J. Bacteriol. 90:1710-1712. 1965.-Satisfactory chromatin staining was obtained with two Bacillus species when nitrogen dioxide was used for fixation in conjunction with either the acid Giemsa or Feulgen staining methods. An impression method was employed for t...

Impact of titanium dioxide nanomaterials on nitrogen fixation rate and intracellular nitrogen storage in Anabaena variabilis.

This study comprehensively investigated the impact of titanium dioxide nanomaterials (nTiO(2)) exposure on cell growth, nitrogen fixation activity, and nitrogen storage dynamics in the primary producer cyanobacteria Anabaena variabilis at various dose concentrations and exposure time lengths. The results indicated that both growth rate (EC(50)-96 h of 0.62 mgTiO(2)/L) and nitrogen fixation acti...

Studies on Nitrogen Fixation by Blue-green Algae I. Nitrogen Fixation by Anabaena Cylindrica Lemm

RECENT work, particularly that of De (1939), has shown that some blue-green algae are capable of utilizing the free nitrogen of the atmosphere in the synthesis of cell material. Much further work will be necessary, however, before the importance of nitrogen fixation by these organisms in nature can be estimated, our knowledge both of the distribution of the property within the group of the Myxo...

Effects of nitric oxide and nitrogen dioxide on bacterial growth.

The effects of low concentrations of nitric oxide (NO) and nitrogen dioxide (NO2) on actively dividing cultures of Staphylococcus aureus, Micrococcus luteus, Micrococcus roseus, Serratia marcescens, Bacillus subtilis, Bacillus circulans, Bacillus megaterium, and Bacillus cereus were studied. Fresh cultures of each organism were incubated for 24 h at 25 degrees C on both nutrient agar and minera...
