Screening of a Planococcus bacterium producing a cold-adapted protease and its application in low-salt fish sauce fermentation
A strain of bacteria isolated from a traditional fermented shrimp paste showed high protease activity at low-temperature (15 degrees C). The strain was identified asPlanococcus maritimusand namedPlanococcus maritimusXJ2.P. maritimusXJ2 grows well in a low-temperature, low-salt, and alkaline environment. The protease produced byP. maritimusXJ2 exhibited the highest enzyme activity at 40 degrees C, pH 9.0 and showed salt tolerance. The amino acid nitrogen content of low-salt fish sauce inoculated withP. maritimusXJ2 was 1.28 +/- 0.04 g/100 ml, which was significantly higher than that of the control withoutP. maritimusXJ2 (0.89 +/- 0.02 g/100 ml,p < .01). The amounts of key desirable volatiles, such as alcohols, ketones, acids, esters, and pyrazine were higher inP. maritimusXJ2 than in the control (p < .05).P. maritimusXJ2 could be used as a starter culture for low-salt fish sauce incubated at 21 degrees C. Practical applications The bacteria identified in this study has a good capacity to ferment the fish for good quality of fish sauce. A new method for the rapid fermentation of low-salt fish sauce and the improvement of its flavor by usingPlanococcus maritimusXJ2 is established. The procedure can help people to produce fish sauce in a shorter time, which will promote the development of fish sauce industry. Therefore, the starter and the method have good practical application in fish sauce produce. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1049026-49-4 is helpful to your research. HPLC of Formula: C5H5BrN2S.
