Investigation of New Potential Uses of Pistacia terebinthus for Various Industries
 ABSTRACT: Pistacia terebinthus has been used extensively in alternative medicine. Inhibitory activity of ethanol fruit extract from P. terebinthus fruit on food-borne and clinical test microorganisms was obtained to determine the potential use of the extract for food and pharmaceutical industries as a natural antimicrobial source. Antibacterial activity of the ethanol extract on fish originated pathogen bacteria was also determined for its potential use in the feed industry. In addition, the effect of the extract on the probiotic bacteria originated from breast milk were tested to obtain the potential use of the extract together with probiotic bacteria for pharmaceutical and food industries. Antimicrobial activity was obtained by performing micro-dilution and macro-dilution assays as well as disc diffusion. Among the food-borne and clinical test microorganisms, the highest inhibition zone diameter (22.39±1.92 mm) was detected on Listeria monocytogenes. The highest antibacterial activity on the fish pathogens was recorded as 17.67±0 mm against Vibrio anguillarum A4. It was determined that P. terebinthus fruit extract had higher antimicrobial activity against some test microorganisms than Amikacin and Gentamicin antibiotics. Antifungal activity on Candida glabrata was also investigated by counting viable cell. At a concentration of 20 mg/mL, no viable cells were determined after 24 hours. The extract inhibited all the tested LAB, however, with low MIC and MBC values. The sun protection factor (SPF) of the extract and the extract+cream mixture at 10 mL concentration was recorded as 9.36 and 7.51. The results of the study indicated that P. terebinthus fruit ethanol extract can be an alternative as a natural additive in various industries such as feed, food, pharmaceutical and cosmetic industries.
