The study aimed to evaluate the antimicrobial activity of certain bioproducts obtained from turmeric and ginger rhizomes, respectively, four essential oils (EO) purchased from NJoy and Oleya and four bioproducts obtained through chloroform and ethanol extraction. The results showed that the EO of ginger (NJoy) exhibits moderate antimicrobial activity against E. coli and significant antimicrobial activity on S. aureus, C. albicans, and C. parapsilosis; the EO of turmeric (Oleya) exhibit moderate antimicrobial activity for E. coli and C. albicans. The bioproduct, derived from the extract of turmeric in chloroform, has a significant antimicrobial effect on C. albicans and C. parapsilopsis. The alcoholic extracts of turmeric and ginger exhibit local antimicrobial effects on E. coli and no antimicrobial activity for C. albicans, C. parapsilopsis, or S. aureus. In conclusion, the preliminary tests achieved in vitro indicate significant differences between the tested bioproducts, some of these showing high potential for specific antimicrobial applications.
