| Abstract: | Objective]The aim of this study was to establish a protocol suitable for isolating and screening strains for pepper decortication.Methods]Strains of bacteria which produce pectinase were isolated from 30 pepper plantation soil samples by preliminary,second screening experiments and decortication experimertis of pepper.Result]Seven strains which could produce peetinase were isolated and screaned two strains had high activity.QH-2 was a promising strain for accelerating decortication of pepper in no more than 4 d,and the sensory evaluation of pepper products achieved superior level.Conclusion]It might provide the basis for subsequent work of isolating strains used for pepper decortication. |
