Intracellular pH determination of pristinamycin-producing Streptomyces pristinaespiralis by image analysis
Article Abstract:
Determination of intracellular pH in pristinamycin-producing Streptomyces pristinaespiralis has been carried out using image analysis and epifluorescence microscopy. It was found that pH(sub.i) correlated with excretion of pristinamycins and glucose consumption during production. If grown in pristinamycin-producing conditions, it had a pH(sub.i) of 6.3-8.7. Such measurement might give clues about physiological states of cells grown in vitro.

High hopanoid/total lipids ratio in Frankia mycelia is not related to the nitrogen status
Article Abstract:
Results demonstrate that in Frankia bacteria remobilization of hopanoids, for the formation of vescicles, occurs under nitrogen-starvation conditions. Data also indicate that under nitrogen-replete conditions the hopanoid contents is slightly elevated.

Evidence for interfacial uptake in hexadecane degradation by Rhodococcus equi: the importance of cell flocculation
Article Abstract:
Rhodococcus equi strains, deficient in biosurfactant formation, take up C(sub)16 alkanes by direct interfacial uptake during their growth on long-chain alkanes as revealed by the degradation kinetics of C(sub)16 alkanes.
