摘要
研究了海带提取物对4种微生物:枯草芽孢杆菌、大肠杆菌、黑曲霉、酵母菌的抗菌作用,并对海带提取物的提取条件进行研究。试验结果表明:海带提取物仅对枯草芽孢杆菌具有抗菌作用;较好的提取溶剂为95%甲醇。最佳提取条件为:温度为30℃,时间为8 h,pH 7。
The anti-bacterial activities of extracts from kelp Laminaria japonica against four microorganism species Bacillus subtilis, Escherichia coli , Aspergillus niger, and Cerevisiae fermented were studied, and the extraction conditions were optimized. The extract from the kelp showed anti-bacterial activity only against Bacillus subtilis. Good extraction and anti-bacterial activities were observed in 95 % methanol under the optimal conditions of pH 7 at 30 ℃ for 8 h based on the inhibition circles.
