Role of competition for inorganic nutrients in the biodegradation mixtures of substrates
Article Abstract:
Competition for inorganic nutrients appears to result in the metabolism of one biodegradable substrate being curtailed by the metabolism of another by a separate organism. The mineralization of benzylamine by Pseudomonas putida could not be enhanced by 100 nM phosphorus when the the medium contained caprolactam and the strain of P. aeruginosa that metabolizes caprolactam. Raising the phosphorus concentration eliminated this suppression. The effects of glutamate, nitrogen and phosphorus in lake water were also assessed.

Influence of calcium, iron and pH on phosphate availability for microbial mineralization of organic chemicals
Article Abstract:
The parameters that influence the availability of phosphate for microbial degradation of glucose, phenol and p-nitrophenol by different strains of Pseudomonas and Corynebacterium were determined. Experiments were conducted to determine the effect of availability of phosphates on microbal degradation and growth. High concentrations of calcium and iron were found to reduce microbial biodegradation of organic chemicals. The effect of pH on mineralization of organic compounds were also established.

Resistance to tellurite as a selection marker fro genetic manipulations of Pseudomonas strains
Article Abstract:
A study was conducted to the resistance to tellurite as a selection market for genetic manipulations of Pseudomonas strains. Escherichia coli strains were utilized as hosts to propagate plasmids supporting an R6K origin of replication. Clones of E. coli and P. putida were pregrown overnight at 37 and 30 degrees C, respectively. In addition, the organization of the minimal replication-transfer segment of the plasmid series was examined.
