Effect of environmental water activity on microbial inactivation by intense pulsed light (IPL).

In this study, the effect of environmental a on microbial inactivation by intense pulsed light (IPL) was investigated. Three different microorganisms (Gram-positive bacteria, Gram-negative bacteria, and yeast) were used as test organisms. The effect of environmental a was assessed by irradiating each microbial suspension in sodium chloride solutions with different environmental a levels (0.

Analysis of microflora profile in Korean traditional nuruk.

A variety of nuruk were collected from various provinces in Korea, and their microflora profiles were analyzed at the species level. A total of 42 nuruk samples were collected and when the viable cell numbers in these nuruk were enumerated, the average cell numbers of bacteria, fungi, yeast, and lactic acid bacteria from all nuruk were 7.21, 7.
