摘要:
Cellulases ofThermomonospora curvatacontain three endoglucanase components. Two of these enzymes (molecular weights of 46 and 106 kD) bound to protein‐extracted lucerne fibres. Maximal adsorption occurred within 6 min, followed by a gradual desorption during fibre hydrolysi

摘要:
Three isolates ofNeocallimastix frontalisgrown in pure culture with glucose as substrate differed in their response to the presence of lasalocid in the growth medium. For two strains (RE1 and RK21) hydrogen production and glucose uptake were reduced to 50% or less of the control values in the presence of lasalocid at 0–25 μg/ ml. A third strain (PNK2) retained significant fermentative ability in the presence of at least four times this amount of lasalocid. Lasalocid was rather less inhibitory to the solubilization of straw by these fungi, PNK2 again providing the most resistant strain. It is concluded that the use of lasalocid in ruminant feeds is likely to have a strain selective effect on the rumen population ofNeocallimast

Sulphate‐reducing bacterial cells, after addition of sodium hydroxide, showed a pink colour under a visible light microscope. This phenomenon is suggested as a test for sulphate‐reducing bacte

摘要:
A simple method is described for the determination of the carbonation tolerance of yeasts. Using the method, data are presented for the carbonation tolerance of some common soft drink spoilage yeasts.

摘要:
Temperature‐dependent compositional changes of phospholipids and their fatty acids were analysed inYersinia enterocoliticagrown at 5°, 25° and 37°C. The relative amounts of the four phospholipids, phosphatidylethanolamine (75–78%), phosphatidylglycerol (10–11%), cardiolipin (<7%) and lysophosphatidylethanolamine (<5%), were essentially the same at all growth temperatures. The degree of fatty acid unsaturation of the four phospholipids increased with decrease in growth temperature, mainly due to an increase of C16:1and C18:1and a corresponding decrease of C16;0, C18:0and cyclo C17:0. An electron spin resonance spectroscopic study of the membrane lipids showed that membrane lipid fluidity was enhanced by decreasing the growth temperatures. The changes in fatty acid composition of phospholipids in response to varied temperatures were consistent with the temperature‐dependent changes in the membrane lipid fluidity ofY. enterocolitica, and were similar to those reported for othe
