Berhi date extract was studied for its effect on the growth of Bacillus subtilis, Staphylococcus aureus, Salmonella typhi and Pseudomonas aeruginosa. From 80 to 99% inhibition was observed in nutrient broth cultures containing 20% (w/v) date extract. Spore germination of B. subtilis was inhibited completely using various concentrations of date extract. Cell elongation and depression in the cell wall of B. subtilis were seen by scanning electron microscopy as a result of incubation in a growth medium containing dates.
研究了椰枣提取物对枯草芽孢杆菌、金黄色葡萄球菌、伤寒沙门氏菌和铜绿假单胞菌生长的影响。在含有20%（w/v）枣提取物的营养肉汤培养物中观察到80%至99%的抑制率。使用不同浓度的枣提取物可完全抑制枯草芽孢杆菌的孢子萌发。通过扫描电子显微镜观察发现，在含有椰枣的生长培养基中培养后，枯草芽孢杆菌的细胞出现伸长和细胞壁凹陷的现象。
