“…The net utilization of protein as an endogenous substrate was first demonstrated by Strange et al (81) with starving suspensions of A. aerogenes, and Gronlund and Campbell (26) indicated that ammonia release by endogenously respiring cells was a general phenomenon. Thus, washed suspensions of E. coli, P. aeruginosa, P. fluorescens, Achromobacter sp., B. subtilis, and S. faecalis all liberate ammonia during endogenous respiration (15,26,87). To this list may be added A. aerogenes (81) [although Gronlund and Campbell (26) did not detect ammonia production with their strain], B. cereus (12, 47), S. lutea (14), S. aureus (64), and N. rugosa (2).…”

“…The rhamnolipid biosurfactant used in this study was extracted from cultures of Pseudomonas aeruginosa American Type Culture Collection (ATCC) 9027 [17]. The bacteria were maintained on Kay's Minimal Medium [18] inoculated with a single colony grown on tryptic soy agar (Difco Laboratories, Detroit, MI, USA).…”

The effect of a rhamnolipid biosurfactant on the reductive dechlorination of polychlorinated biphenyls was investigated with the use of clean sediments spiked with Aroclor 1248. The surfactant was added to the contaminated sediments at four different concentrations (5, 10, 25, and 50 microg/g sediment [ppm] on a sediment dry wt basis), and dechlorination was followed over a 40-week period. The rate of overall dechlorination was enhanced at the three highest concentrations. Dechlorination at the lowest concentration (5 ppm) was not different from that in surfactant-free sediments. On a congener basis, enhanced dechlorination was mostly found in the congeners that have high threshold concentrations for dechlorination. These congeners are characterized by an initial increase in concentration before dechlorination starts. At the three highest biosurfactant concentrations, this initial concentration increase was absent or dramatically reduced. Therefore, the enhancement in dechlorination appears to be caused by an increase in bioavailability at high surfactant concentrations. The biosurfactant also reduced the lag time before dechlorination began in these congeners. Among those congeners that have low threshold concentrations, dechlorination enhancement was found only in two peaks. For these two, there was no lag period, either with or without the rhamnolipids. The maximum level of dechlorination and the congener pattern of final dechlorination products were identical, regardless of biosurfactant concentration.

“…She found that the fermentation of sugars by Pseudomonas cultures was masked in the peptone medium by the production of free ammonium and a consequently high pH value. The recent studies of Warren, Ells & Campbell (1960) indicated that P. aeruginosa grown in a glucose ammonium phosphate medium accumulated nitrogenous materials which were oxidized during endogenous respiration. Rhodes (1959) found that after incubation for 7 days in peptone water the pH values of the media of all Pseudomonas strains studied were between pH 8.3 and pH 8.7.…”

The rate of 0, utilization by both pigmented and non-pigmented strains of Pseudosmonas aeruginosa was greater with 2 yo (~1 1 7) Casitone as substrate than with 0.1 M-glucose as substrate. P. aeruginosa readily catabolized Casitone, amino acids and other nitrogenous compounds with the production of an alkaline reaction even in the presence of 0.5 0 4 (wlv) glucose. Other species of Pseudomonas studied varied in their utilization of these compounds, suggesting a different and possibly satisfactory approach to the identification and classification of species within the genus Pseudornonas.
