Cyclic electron flow around photosystem (PS) I has been widely described in vitro in chloroplasts or thylakoids isolated from C(3) plant leaves, but its occurrence in vivo is still a matter of debate. Photoacoustic spectroscopy and kinetic spectrophotometry were used to analyze cyclic PS I activity in tobacco (Nicotiana tabacum cv Petit Havana) leaf discs illuminated with far-red light. Only a ...

In spinal mice the latent period between decapitation and the disappearance of all spinal reflexes decreases regularly with increasing age (Fig. 1). Available evidence indicates that this latent period may be proportional to the capacity for anaerobic metabolism at various ages.

26 27 Two bacterial species, Pseudomonas aeruginosa and Lactococcus lactis, with different 28 metabolic features, were used as a comparative experimental model to investigate the antimicrobial 29 target and mechanism of transferrins. In anaerobiosis, P. aeruginosa cells were not susceptible to 30 lactoferrin (hLf) or transferrin (hTf). In aerobiosis, the cells were susceptible but O2-consumptio...

OBJECTIVES To evaluate the performance of the Anoxomat, in comparison with the conventional anaerobic GasPak jar system, for the isolation of obligate anaerobes. METHOD Anoxomat, model WS800, and anaerobic GasPak jar system (Oxoid) were evaluated. Anoxomat system utilized a gas mixture of 80% N(2), 10% CO(2) and 10% H(2), while the GasPak used a gas mixture of 90% H(2) and 10% CO(2). An anaer...
