Pectin hydrolysis by certain salt-tolerant yeasts.
During the brine fermentation of cucumbers for pickles, Bell et al. (1950) have reported finding a fungal-type polygalacturonase-like enzyme which splits the polymer linkage of pectic substances. They definitely established this enzyme with the softening type of spoilage of salt-stock pickles brined under commercial conditions. With the identity of the softening agent known, an inquiry into its...
متن کاملPectin methylesterase, metal ions and plant cell-wall extension. Hydrolysis of pectin by plant cell-wall pectin methylesterase.
The hydrolysis of p-nitrophenyl acetate catalysed by pectin methylesterase is competitively inhibited by pectin and does not require metal ions to occur. The results suggest that the activastion by metal ions may be explained by assuming that they interact with the substrate rather than with the enzyme. With pectin used as substrate, metal ions are required in order to allow the hydrolysis to o...
متن کاملRapid method for detection of urea hydrolysis by yeasts.
A method is described for the rapid detection of urea hydrolysis by yeasts, using the Berthelot color reaction. The results could be determined within 30 to 50 min with this method, compared with 8 to 72 h usually required with Christensen urea agar.
متن کاملNicotinic Acid Requirements of Certain Yeasts.
Knowledge of the accessory growth factors concerned in the physiology of lactose-fermenting yeasts was needed in an investigation of fermentation that was being conducted by the Bureau of Dairy Industry. Since information on nicotinic acid requirements for the growth of yeasts not fermenting lactose was at best fragmentary and incomplete and information on lactose-fermenting yeasts was complete...
متن کاملNetwork-based transcriptome analysis in salt tolerant and salt sensitive maize (Zea mays L.) genotypes
Identification of genes involved in salinity stress tolerance provides deeper insight into molecular mechanisms underlying salinity tolerance in maize. The present study was conducted in the faculty of agriculture of Urmia university, Iran, in 2018, with the aim of identifying genetic differences between two maize genotypes in tolerance to salinity stress, and the results of gene expression wer...
