摘　　要：为了充分利用螠蛏贝壳资源开发新型生态补钙制剂,用两种乳酸菌发酵螠蛏贝壳粉,以发酵结束后乳酸菌的活菌数和游离钙转化率为指标,优选出最佳发酵工艺。研究结果表明,最佳发酵条件为300目粒度的螠蛏贝壳粉15%,蔗糖8%,1∶1混合的保加利亚杆菌和嗜热链球菌接种量7%,发酵30 h。To developing new biological calcium product, two kinds of lactobacillus were used for ferment the shell powder of Sinonovacula constricta. The ferment conditions were defined through comparing the total number of live lactobacilli and the conversion of ionic calcium. Research results suggest that the optimal conditions were adding 15 % shell powder of 300 mesh, 8 % sugar and 7 % admixture of lactobacillus bulgaricus and streptococcus thermophilus, fermentation for 30 h.
