Abstract：
In this work, we evaluated the protective capacity of Spirulina platensis biomass in preserving Lactobacillus delbrueckii subsp. bulgaricus WDCM 00102. The L. bulgaricus strain was freeze-dried in the presence of S. platensis biomass and the freeze-dried samples were then stored at 5 and 25°C for varying periods. Subsequently, the samples were rehydrated and bacterial plate counts were determined. The results indicate that a concentration of 12% S. platensis biomass was highly effective in preserving L. bulgaricus. Commercial products with higher S. platensis biomass content exhibited greater protective capacity. While S. platensis biomass is well-known for its prebiotic properties, its protective role has not been previously reported or thoroughly explored. This study demonstrates the protective capacity of S. platensis biomass in preserving L. bulgaricus, a strain particularly sensitive to preservation processes.
摘要：
在这项工作中,我们评估了螺旋藻生物量在保存德氏乳杆菌亚种中的保护能力。保加利亚WDCM00102。在S.platensis生物质存在下将保加利亚乳杆菌菌株冷冻干燥,然后将冷冻干燥的样品在5和25°C下储存不同的时间。随后，将样品再水化并测定细菌平板计数。结果表明，浓度为12％的巴氏链球菌生物量对保存保加利亚乳杆菌非常有效。具有较高的S.platensis生物量含量的商业产品表现出更大的保护能力。虽然S.platensis生物质以其益生元特性而闻名，它的保护作用以前没有报道或彻底探索过。这项研究证明了S.platensis生物量在保存保加利亚乳杆菌中的保护能力，对保存过程特别敏感的菌株。
