| detection of alcohols and volatile fatty acids by head-space gas chromatography in identification of anaerobic bacteria. | a head-space gas chromatographic technique for the analysis of volatile bacterial metabolites is described. bacteroides fragilis, clostridium perfringens, and propionibacterium acnes, cultured in a glucose-containing peptone yeast extract medium, were studied. the head-space technique was compared with the injection of the complete liquid culture medium, and solvent extracts thereof, into the gas chromatograph. volatile fatty acids could be detected by all three methods, whereas alcohols produce ... | 1978 | 203602 |
| influence of ph extremes on sporulation and ultrastructure of sarcina ventriculi. | distinct morphological changes in the ultrastructure of sarcina ventriculi were observed when cells were grown in medium of constant composition at ph extremes of 3.0 and 8.0. transmission electron microscopy revealed that at low ph (less than or equal to 3.0) the cells formed regular packets and cell division was uniform. when the ph was increased (to greater than or equal to 7.0), the cells became larger and cell division resulted in irregular cells that varied in shape and size. sporulation o ... | 1989 | 2738022 |
| interaction between bambuterol and physostigmine: aspects on cholinesterase inhibition and neuromuscular transmission in the smooth and skeletal muscles of the guinea-pig. | bambuterol, the bis-dimethyl carbamate prodrug of terbutaline, and physostigmine were examined with respect to their ability to interfere with the neuromuscular transmission in an isolated vagus nerve-trachea preparation, a phrenic nerve-diaphragm preparation and the transmurally stimulated extensor digotorum longus (edl) isolated from the guinea-pig. physostigmine increased the contractile response of the trachea to stimulation of the vagus nerve. bambuterol had an opposite effect in this respe ... | 1988 | 2848230 |
