s-Triazines as Nitrogen Sources for Bacteria
Isolation of bacteria able to utilize s-triazines as the sole and limiting nitrogen sources for growth is described. Three strains of Pseudomonas (A, D, and F) and two strains of Klebsiella pneumoniae (90 and 99) were examined. Strains D and F utilized N-ethylammelide, N-isopropylammelide, ammeline, ammelide, cyanuric acid, and ammonium ion as nitrogen sources. Strain A utilized melamine, ammel...
متن کاملBiodegradation of Chlorinated s-Triazines
The catabolism of chlorinated s-triazines, e.g., herbicides, is incompletely understood. The first demonstration of their quantitative microbial degradation is the fungal dealkylation of simazine (CEET [for meaning of abbreviations throughout, see Table 1, footnote a]) to two major products, deethylsimazine (CEAT; two-thirds of total) and an unidentified s-triazine (one-third of total) (11, 12)...
متن کاملMagnetotactic Bacteria as Potential Sources of Bioproducts
Magnetotactic bacteria (MTB) produce intracellular organelles called magnetosomes which are magnetic nanoparticles composed of magnetite (Fe3O4) or greigite (Fe3S4) enveloped by a lipid bilayer. The synthesis of a magnetosome is through a genetically controlled process in which the bacterium has control over the composition, direction of crystal growth, and the size and shape of the mineral cry...
متن کاملNitrate and ammonia as nitrogen sources for deep subsurface microorganisms
We investigated the N-utilizing bacterial community in anoxic brackish groundwater of the low and intermediate level nuclear waste repository cave in Olkiluoto, Finland, at 100 m depth using (15)N-based stable isotope probing (SIP) and enrichment with (14∕15)N-ammonium or (14∕15)N-nitrate complemented with methane. Twenty-eight days of incubation at 12°C increased the concentration of bacterial...
متن کاملHeme compounds as iron sources for nonpathogenic Rhizobium bacteria.
Many animal-pathogenic bacteria can use heme compounds as iron sources. Like these microorganisms, rhizobium strains interact with host organisms where heme compounds are available. Results presented in this paper indicate that the use of hemoglobin as an iron source is not restricted to animal-pathogenic microorganisms. We also demonstrate that heme, hemoglobin, and leghemoglobin can act as ir...
