Acetylene reduction (nitrogen fixation) by pulp and paper mill effluents and by Klebsiella isolated from effluents and environmental situations.
High rates of acetylene (C(2)H(2)) reduction (nitrogenase activity) were observed in woodroom effluent from a neutral sulfite semi-chemical mill under aerobic (up to 644 nmol of C(2)H(4) produced per ml per h) and under anaerobic (up to 135 nmol of C(2)H(4) produced per ml per h) conditions. Pasteurized effluent developed C(2)H(2) reduction activity when incubated under anaerobic but not under ...
متن کاملNitrogen fixation (acetylene reduction) by epiphytes of freshwater macrophytes.
The involvement of epiphytic microorganisms in nitrogen fixation was investigated in a shallow freshwater pond near Ithaca, N.Y. The acetylene reduction technique was used to follow diel and seasonal cycles of nitrogen fixation by epiphytes of Myriophyllum spicatum. Acetylene-reducing activity was maximal between noon and 6 p.m., but substantial levels of activity relative to daytime rates cont...
متن کاملLimitation of acetylene reduction (nitrogen fixation) by photosynthesis in soybean having low water potentials.
The role of photosynthesis and transpiration in the desiccation-induced inhibition of acetylene reduction (nitrogen fixation) was investigated in soybean (Glycine max [L.] Merr. var. Beeson) using an apparatus that permitted simultaneous measurements of acetylene reduction, net photosynthesis, and transpiration. The inhibition of acetylene reduction caused by low water potentials and their afte...
متن کاملNitrogen Fixation (Acetylene Reduction) by Rhizosphere Sediments of the Eelgrass Zostera marina
Nitrogen fixation (acetylene reduction) was consistently and immediately detectable in rhizosphere sediments of the eelgrass Zostera marina L. collected from several stations and at various times of the year Nitrogenase activity was detected down to 12 cm with the major fraction occurring in the 0 to 6 cm segment. Nitrate and NH,+ (100 to 200 &M) inhibited nitrogenase activity, while glucose (1...
متن کاملAcetylene reduction (dinitrogen fixation) by clinical isolates of Klebsiella pneumoniae.
Freshly isolated clinical strains of Klebsiella were tested for the ability to fix dinitrogen by the acetylene reduction assay. Ability to detect this trait was markedly affected by cultural conditions. When the test was run at 37 degrees C in the presence of yeast extract (50 mg/liter), only 1.6% of the organisms were diazotrophs, whereas this temperature without yeast extract yielded 12.9% po...
