Used in Food and Beverage Industry:
D-Lactic Acid Sodium Salt is used as a flavor enhancer and preservative in the food and beverage industry, providing a mild, slightly sweet taste and extending the shelf life of products.
Used in Cosmetics and Personal Care Industry:
D-Lactic Acid Sodium Salt is used as a humectant and pH adjuster in cosmetics and personal care products, helping to retain moisture and maintain the desired pH for optimal product performance and skin compatibility.
Used in Biotechnology and Research:
D-Lactic Acid Sodium Salt is used in biotechnology and research applications, such as cell culture media and enzyme assays, due to its ability to provide a stable environment for biological processes and reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 920-49-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 920-49:
(5*9)+(4*2)+(3*0)+(2*4)+(1*9)=70
70 % 10 = 0
So 920-49-0 is a valid CAS Registry Number.

Discovery and characterization of a thermostable D-lactate dehydrogenase from Lactobacillus jensenii through genome mining

The demand on thermostable D-lactate dehydrogenases (d-LDH) has been increased for d-lactic acid production but thermostable d-DLHs with industrially applicable activity were not much explored. To identify a thermostable d-LDH, three d-LDHs from different Lactobacillus jensenii strains were screened by genome mining and then expressed in Escherichia coli. One of the three d-LDHs (d-LDH3) exhibited higher optimal reaction temperature (50 °C) than the others. The T5010 value of this thermostable d-LDH3 was 48.3 °C, much higher than the T5010 values of the others (42.7 and 42.9 °C) and that of a commercial D-lactate dehydrogenase (41.2 °C). The Tm values were 48.6, 45.7 and 55.7 °C for the three d-LDHs, respectively. In addition, kinetic parameter (k cat/Km) of d-LDH3 for pyruvate reduction was estimated to be almost 150 times higher than that for lactate oxidation at pH 8.0 and 25 °C, implying that D-lactate production from pyruvate is highly favored. These superior thermal and kinetic features would make the d-LDH3 characterized in this study a good candidate for the microbial production of D-lactate at high temperature from glucose if it is genetically introduced to lactate producing microbial.
