体外研究 |
Most of the gram-positive and some gram-negative bacteria are sensitive to trans 4-Hydroxycinnamic acid (4-HBA) and 4-Hydroxybenzoic acid at IC50 concentrations of 100-170 and 160μg/mL,respectively.The antimicrobial activities of 4-Hydroxycinnamic acid and t4-HCA against 11 food pathogenic bacteria,6 plant pathogenic bacteria,2 yeasts and 15 plant pathogenic fungi are tested by the paper disc method.These compounds inhibit the growth of most of the bacteria and yeasts at concentrations of 200-400μg.However,the inhibition is more effective against most of the gram-positive bacteria.When tested by the paper disc method,4-Hydroxycinnamic acid has stronger antimicrobial activity than t4-HCA against S.aureus,L.mesenteroides,S.cerevisiae and C.albicans at a concentration of 50μg.However,no inhibitory effect against fungi was observed at concentrations even up to 1000μg. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
