Isolation,identification and application of Pediococcus pentosaceus from pickled cabbage
摘要
Abstract
To explore the influence of Pediococcus pentosaceus strain on pickled cabbage,four strains of Pediococcus pentosaceus were isolated and identified from pickled cabbage collected in Dali,Yunnan.Their characteristics,including growth curves,acid production ability,antibacterial activity,nitrite degradation capacity and antioxidant properties were studied in vitro,and subsequently applied in a vegetable pickling process for validation.The strain comprehensive performance score followed the order of RS-08>RS-25>RS-34>RS-12,with RS-08 exhibiting the best overall performance(P＜0.05).Compared with the naturally fermented control groups,inoculation with P.pentosaceus significantly enhanced viable cell counts and reduced the final nitrite content in the product(P＜0.05),with RS-08 achieving the lowest nitrite level and the strongest acid production ability(P＜0.05).Furthermore,the strains significantly improved the antioxidant capacity of pickled cabbage,showing higher scavenging rates for ABTS+,DPPH,and hydroxyl radicals compared to the control group(P＜0.05),with RS-08 demonstrating the strongest effect.Comprehensive scoring showed that all four experimental groups were significantly superior to the naturally fermented group(P＜0.05),with the strain RS-08 achieving the highest score of 98.50±1.97(P＜0.05).In conclusion,all four screened strains of P.pentosaceus were beneficial for pickling,as they could shorten the fermentation time,effectively reduce the nitrite content,and improve the overall quality of pickled cabbage.Strain RS-08 was identified as the most effective strain.All four strains are suitable as potential starters in industrial-scale pickled cabbage production.关键词
