Fate of Nitrogen-Fixing Bacteria in Crude Oil Contaminated Wetland Ultisol
The effect of crude oil on the growth of legumes (Calopogonium muconoides and Centrosema pubescens) and fate of nitrogen-fixing bacteria in wetland ultisol was investigated using standard cultural techniques. The results revealed observable effects of oil on soil physico-chemistry, plant growth and nodulation as well as on densities of heterotrophic, hydrocarbonoclastic and nitrogen fixing bact...
متن کاملNitrogen-fixing (acetylene redution) activity and population of aerobic heterotrophic nitrogen-fixing bacteria associated with wetland rice.
Nitrogen-fixing activity associated with different wetland rice varieties was measured at various growth stages by an in situ acetylene reduction method after the activities of blue-green algae (cyanobacteria) in the flood water and on the lower portion of the rice stem were eliminated. Nitrogen-fixing activities associated with rice varieties differed with plant growth stages. The activities i...
متن کاملFerredoxins from Nitrogen-Fixing Bacteria
Two ferredoxins have been purified from N2-fixing Mycobacterium flavum. Ferredoxin I had a minimum molecular weight (by amino acid analysis) of 11 230 and contained 7.4 mol Fe and 7.0 mol S2per mol. The ratio of the absorbance at 400 nm to that at 275 nm was 0.7. Ferredoxin I1 had a minimum molecular weight of 13478 and contained 3.4 mol Fe and 3.2 mol S2per mol. The ratio of the absorbance at ...
متن کاملNitrogen-Fixing Bacteria in Eucalyptus globulus Plantations
Eucalypt cultivation is an important economic activity worldwide. In Portugal, Eucalyptus globulus plantations account for one-third of the total forested area. The nutritional requirements of this crop have been well studied, and nitrogen (N) is one of the most important elements required for vegetal growth. N dynamics in soils are influenced by microorganisms, such as diazotrophic bacteria (D...
متن کاملDevelopment of Three Bacteria Consortium for the Bioremediation of Crude Petroleum-oil in Contaminated Water
We have to developed active microbial consortium that could be of higher degradation of crude oil contaminated groundwater, wastewater aeration pond and biopond at the oil refinery Terengganu Malaysia. Among four isolates that showed good growth only three different isolates (Acinetobacter faecalis WD2, Staphylococcus. sp DD3 and Neisseria elongate TDA4.) were selected based on the growth abili...
