The fermentation characteristics of lactic acid bacteria from the commercial start culture were studied in goat milk. The results showed that L.b-300 and L.b-800 strains have stronger acid-production capacity,and S.t-499 strain has stronger visco-production capacity while L.b-300 and S.t-800 strains with stronger odor-production capacity. The post-acidification capacities of eight lactic acid bacteria strains were weak.The L.b-300 and S.t-499 strains were suitable for goat milk fermentation.
