A Preliminary Study on Probiotic Characteristics of Sporosarcina spp. for Poultry Applications

摘要: Probiotics are well known for their wide range of beneficial activities. However, recent use probiotic Bifidobacterium, Enterococcus, and Lactobacillus spp. has been plagued by certain disadvantages such as complex growth requirements, high maintenance cost, susceptibility to the gastrointestinal environment, pathogenic gene transfer, non-standardized dosage, cell lysis at extreme acidic pH, widespread antibiotic resistance, lower bacterial viability due lack spore formation. Therefore, spore-forming bacteria belonging Sporosarcina genus pasteurii, globispora, psychrophila were assessed characteristics biofilm formation, intestinal adhesion, acid bile tolerance, sensitivity, anti-pathogenic activity. This ensures under conditions enabled same colonize effectively in lumen (in vitro). The counts ranging from 6.59 6.91 log(CFU/mL) was observed after 16 h. indicated that there is no significant difference (P-value = 0.90). 5.57 5.93 log(CFU/mL) displayed strong tolerance pH 2. They also viable higher (0.5%) concentration. Among spp., pasteurii showed better (6.90 log(CFU/mL)) even selected bacteria, more susceptible teicoplanin meropenem with an inhibition zone 30 mm. Maximum antagonistic activity against Serratia marcescens (with up 15 mm). Our results suggest possess all required be used potential poultry probiotics.
