Characteristics of Tartrate-fermenting Species of Clostridium.

The characteristics of lactate-fermenting sporeforming anaerobes from silage.

In studies on the sporeforming anaerobic bacteria in orchard grass silages, two groups were found to predominate on the basis of spore counts (Bryant et at., 1952). Several proteolytic strains isolated were similar to Clo8tri4ium sporogenes, but the majority of isolates were lactatefermenting anaerobes which were similar to Clostridium tyrobutyricum (van Beynum and Pette, 1935). Since the work ...

Discrimination of d-tartrate-fermenting and -nonfermenting Salmonella enterica subsp. enterica isolates by genotypic and phenotypic methods.

A multiplex PCR and an improved lead acetate test were developed to discriminate d-tartrate-fermenting and -nonfermenting Salmonella enterica subsp. enterica strains. Both methods showed an accuracy of 100% when 125 Salmonella strains belonging to 15 serovars were tested. Special emphasis was given to S. enterica subsp. enterica serovar Paratyphi B isolates because of the clinical importance of...

تأثیر یون تارتارات بر رفتار جدایش روی و کادمیم در محلول سولفاتی

The aim of this study was to investigate the effect of tartrate ion (C4H4O62-) on the extraction and separation of zinc and cadmium using D2EHPA extractant. The presence of tartrate ion in the solution caused the shift of  the  extraction curve of zinc and cadmium to the more alkaline pH; however, the shifting rate for the cadmium extraction curve was more significant. In the absence of tartrat...

Characteristics of a bacteriocin -like substance produced by Clostridium haemolyticum strain IRP - 135

A New Type of Glucose Fermentation by Clostridium thermoaceticum.

The thermophilic fermentation of cellulosic material is generally regarded -as a result of the combined action of several species of bacteria, some of which attack the cellulose and others the sugars formed from the breakdown of the cellulose. Much effort has been spent on attempts to isolate the cellulose fermenters but very little attention has been paid to the associated sugar-fermenting org...
