Pyridine-2,6-bis(thiocarboxylic acid) produced by Pseudomonas stutzeri KC reduces and precipitates selenium and tellurium oxyanions

Article Abstract:

The nature of selenium and tellurium precipitates formed upon interaction with pyridine-2,6-bis(thiocarboxylic acid) (pdtc) and the role of pdtc in detoxification of the bacterial environment is investigated and a chemical mechanism is proposed for interactions of pdtc with selenite and tellurite. The pdtc-producing Pseudomonas stutzeri KC has shown higher tolerance against selenite and tellurite toxicity than a pdtc-negative mutant strain, CTN1.

Use of stochastic models to assess the effect of environmental factors on microbial growth

Article Abstract:

A novel application of a stochastic ecological model is presented to the study and analysis of microbial growth dynamics as influenced by environmental conditions in an extensive data set. The model proved to be useful in bridging the gap between theoretical ideas in ecology and an applied problem in microbiology.
