The effect of agar on the inhibitory activity of phenols

The Effect of Washed Agar on the Inhibitory Activities of Phenols

“…(5) 2-methyl-6-test-butylphenol and 2, 6-di-tert-butyl-4-methylphenol was confirmed. It is interesting to note that out of the 30 phenolic compounds studied by SANDS et al (5) and in this investigation, one-half were not adversely affected by agar.…”

“…This study is a continuation of the investigation by SANDS et al (5). This investigation had two objectives.…”

“…Coox (4) also demonstrated that agar interfered with the inhibitory activity of chlorocresol. Recently SANDS et al (5) studied the effect of agar on the inhibitory activity of 19 phenolic compounds using Staphylococcus aureus as the test organism.…”

Antibiotic Activity in the Presence of Agar

“…The culture of Staphylococcus aureus employed in previous studies (13,24,25) was used throughout this investigation. The organisms were stored on nutrient agar at 4 C and were transferred every 4 days.…”

“…Previous studies in this laboratory have shown that the presence of agar in a test medium can seriously interfere with the inhibitory activities of antimicrobial agents (13,24,25). In an effort to overcome this interference, agar was extracted with water prior to use in the medium.…”
