The present study aimed to determine the antimicrobial activity of methanol, acetone, ethanol, or heptane ex-tracts from L. papillosa or C. officinalis with the skin and mucus extracts from S. aurata. The inhibition zone (IZ) and minimum inhibitory concentration (MIC) of the extracts against Acinetobacter baumannii, Klebsiella pneumoniae, Staphylococcus aureus, Enterococcus faecalis, Candida tropicalis, and C. parapsilosis were de-termined by well diffusion and spectrophotometric broth microdilution methods, respectively. The highest an-timicrobial activity of L. papillosa was against C. tropicalis with 4.98 mm, and the highest activity of C. offic-inalis was against E. faecalis with 7.84 mm. Among S. aurata mucus and skin extracts, the highest activity was on C. parapsilosis with 13.82 mm. The antimicrobial effect of S. aurata mucus extract on E. faecalis was found to be almost the same as L. papillosa extracts (6.14 mm and 6.43 mm). The inhibitions of S. au-rata aqueous phase extract on K. pneumoniae and C. parapsilosis (7.09 mm) were much greater than the ef-fects of L. papillosa and C. officinalis extraction. That S. aurata mucus and skin extracts were very effective, especially on K. pneumoniae, A. baumannii and Candida sp., was showed for the first time with this study. As a result, S. aurata mucus content is more effective on K. pneumoniae and C. parapsilosis than the phenol-ic content of both algae.
