Biological elimination of H2S and NH3 from wastegases by biofilter packed with immobilized heterotrophic bacteria.
Biotreatment of various ratios of H2S and NH3 gas mixtures was studied using the biofilters, packed with co-immobilized cells (Arthrobacter oxydans CH8 for NH3 and Pseudomonas putida CH11 for H2S). Extensive tests to determine removal characteristics, removal efficiency, removal kinetics, and pressure drops of the biofilters were performed. To estimate the largest allowable inlet concentration,...
متن کاملNew medium for isolating iron-oxidizing and heterotrophic acidophilic bacteria from acid mine drainage.
A new solid medium is described for growing iron and heterotrophic bacteria from acid mine drainage (AMD). Examination of AMD from five states revealed several kinds of colonies of iron-oxidizing bacteria: (i) smooth, (ii) smooth with secondary growth sectors or branching, (iii) star-shaped, (iv) radiating lobe, and (v) flat-rough. All AMD samples yielded whitish colonies that could not use fer...
متن کاملLeaching of pyrite by acidophilic heterotrophic iron-oxidizing bacteria in pure and mixed cultures.
Seven strains of heterotrophic iron-oxidizing acidophilic bacteria were examined to determine their abilities to promote oxidative dissolution of pyrite (FeS2) when they were grown in pure cultures and in mixed cultures with sulfur-oxidizing Thiobacillus spp. Only one of the isolates (strain T-24) oxidized pyrite when it was grown in pyrite-basal salts medium. However, when pyrite-containing cu...
متن کاملHydrogen Oxidizing Bacteria as Poly(hydroxybutyrate) Producers
Batch culture of Ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. The gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...
متن کاملIdentification, characterization and application of sulfide- oxidizing bacteria in oil fields
The cycling of sulfur in oil field brines has focused predominantly on bacteria involved in the reduction of sulfur species to sulfides, which are detrimental to the production of these fields. However, recent interest in the addition of nitrates and nitrites to oil field brines for the remediation and control of sulfides has rekindled new interest in sulfide bio-oxidation. Addition of nitrate ...
