TL;DR: A novel, inducible, carbon-phosphorus bond-cleavage enzyme, phosphonoacetate hydrolase, was purified from cells of Pseudomonas fluorescens 23F grown on phosphono acetate and displayed no significant similarity to other databank sequences.

TL;DR: Phosphonopyruvate hydrolase, a novel bacterial carbon-phosphorus bond cleavage enzyme, was purified to homogeneity by a series of chromatographic steps from cell extracts of a newly isolated environmental strain of Variovorax sp.

TL;DR: Nine proprietary homoserine lactone compounds were screened, using water as a control, for their effect on the lag phase duration and exponential growth rate of three strains of Pseudomonas fluorescens isolated from refrigerated raw milk after 1, 3 and 5 days storage to determine the extent to which extracellular enzyme production is mediated by the quorum sensing phenomenon in this species.

TL;DR: Findings indicate that there is no causal relationship between selective growth advantage and ability to produce proteinase and lipase and indicates that the spoilage of pasteurized milk is a complex phenomenon and is worthy of further research.
