- This study aims to examine the growth characteristics of B. cereus and B. zhangzhouensis and to see their potential in preventing the growth of Aeromonas hydrophila in vitro. This research was conducted in June 2020 - May 2021 at the Laboratory of Microbiology and Biotechnology, Faculty of Fisheries and Marine Sciences, Padjadjaran University. The method used is the exploratory method and the data obtained were analyzed descriptively. The growth curve was performed using the turbidimetric method. The inhibition test used the disc diffusion method with 5 treatments, chloramphenicol antibiotics (4000 ppm), distilled water, bacterial culture, 100% supernatant and 50% supernatant. The curve results showed that the growth of B. cereus and B. zhangzhouensis was slow. The stationary phase of B. cereus occurred at 40-72 hours, while in B. zhangzhouensis the stationary phase occurred at 48-72 hours. The results of the inhibition test showed that the antimicrobial activity of B. cereus and B. zhangzhouensis was weak with a value range of 0.71 - 1.6mm, besides that the results of the inhibition zone produced by these two bacteria have different inhibitory abilities in each treatment.
