摘要
Abstract
The nitrate reduction of Kluyvera cryocrescens isolated from ginger and its propagation at different temperature , concentration of sodium chloride, and pH valu was studied. The role of Kluyvera cryocrescens on nitrite generation of ginger was observed. The results showed that Kluyvera cryocrescens could reduce nitrate to nitrite. It did not propagate at 1℃ , but propagated slowly at 4℃ and rapidly at 8℃. It propagated well in 0. 5% , 1% , 2% sodium chloride medium, but died slowly in 5% sodium chloride medium. It propagated well at pH5. 0 ~7. 0 in culture medium , but died gradually at pH4. 0. Nitrite could be detected in 4 to 8 days after gingers were contaminated by Kluyvera cryocrescens. Nitrite content was at peak when Kluyvera cryocrescens reached 10 CFU/g in most of gingers.关键词
