acid resistance การใช้

• Novolac epoxies are particularly noted for chemical resistance and acid resistance.
• Current thinking is that acid resistance, particularly in strain WSM419, can be transferred on plasmids.
• The extreme acid resistance of " Z . bailii " has been reported by many authors.
• It has been shown by gene deletion that GcvB is a regulator of acid resistance in " E . coli ".
• Also, from about 1830 they started production of salt glaze stoneware vessels, which were valued for their acid resistance, for the emerging chemical industries.
• Hence, it is conceivable that " Z . bailii " puts more effort on limiting the influx of acids in order to enhance its acid resistance.
• Some less visible distinctions amongst tank trucks have to do with their intended use : compliance with human food regulations, refrigeration capability, acid resistance, pressurization capability, and more.
• Some studies have revealed the negligible effects of different sugars on preservative resistance of " Z . bailii ", e . g . comparable sorbic and benzoic acid resistance was observed regardless whether the cells were grown in culture medium containing glucose or fructose as fermentable substrates.
• GadY can form base pairs with the 3'UTR of its target mRNA gadX, this pairing is thought to confer increased stability to the transcript, allowing accumulation of gadX ( a transcriptional regulator of the acid response ) and therefore increased expression of downstream acid resistance genes.
• Similarly, ethanol levels up to 10 % ( v / v ) did not adversely influence sorbic and benzoic acid resistance of the yeast at pH 4.0-5.0 . have proved that in " Z . bailii ", ethanol plays a protective role against the negative effect of acetic acid by inhibiting the transport and accumulation of this acid intracellularly.
