Tricyclic pyrazole derivatives (698) are described by Hashem et al. as inhibitors of the growth of Bacillus subtilis, Pseudomonas fluorescens, Staphylococcus aureus and KB cells at moderate concentrations (76JMC229).

A new model (Fig. 15.4) for hydroxy-cinnamate chain-shortening and vanillin formation in plants was revealed with the isolation of 4-hydroxycinnamoyl-CoA hydratase/lyase (HCHL) and its gene from a soil bacterium, Pseudomonas fluorescens strain AN103, which had been isolated by growth on ferulic acid as a sole carbon source (Gasson et al., 1998 Narbad and Gasson, 1998 Mitra et al., 1999).

Pseudomonas fluorescens Pf5 is a plant commensal of the rhizosphere that suppresses the growth of various plant pathogens. The sequenced genome was found to harbor nine secondary metabolite gene clusters. Six of these could be attributed to known biosynthetic pathways for pyoluteorin (23) (Scheme 4),... 

Most of the tested secoiridoids displayed an inhibition of the growth of B. subtilis and P. fluorescens (Table 9). Insularoside (15) and hydroxyomoside (17) are more active against B. subtilis. The mixture of hydroxyframoside A, B (20a, b) showed the best activity against Pseudomonas fluorescens. 

Table 12.1 gives data on the nutrient used for the laboratory growth of Pseudomonas fluorescens and illustrates the relative amounts of different constituents including trace elements to sustain healthy growth of the cells. 

In Section 12.2 the need for trace elements was discussed. Work by Santos [1993] reveals that unless trace elements are present biofilm growth on a surface exposed to a flowing system of bacteria Pseudomonas fluorescens), is severely restricted. Fig. 12.22 shows that when trace elements were added (after approximately 800 hours) there was a remarkable sudden growth in biofilm. 

The range of phosphonic acids which can be utilized enzymically (at least by those enzymes present in Pseudomonas fluorescens) has recently been extended to include aminoalkyl-, hydroxyalkyl- and oxoalkyl-phosphonic acids, as well as phosphonodipep-tides only slight growth was seen with the herbicide glyphosate (A-phosphonomethyl-glycine (83), which is metabolized to (aminomethyl)phosphonic acid, and neither phos-phinothricin (84) nor its dialanyl tripeptide bialaphos supports growth in contrast to the behaviour of other bacterial extracts isolated from soil ". ... 

For point (ii) the predictions given above agree with the results of Henrici (H7) on growth of E. coli, and with those of Rabotnova and Mineeva (Rl) on growth of Torulopsis utilis and Pseudomonas fluorescens. The maximum concentration of organism attained becomes roughly independent of inoculum size and dependent on initial substrate concentration, as known since Henrici s experiments (H7).
