Background: Aeromonas hydrophila is a heterotrophic, Gram-negative, rod-shaped, facultative
anaerobic, non-spore forming bacteria that are autochthonous and widely dispersed in marine environments.
The study aims at investigating the screening of Aeromonas hydrophila from spoiled vegetables
and the sediment sample collected from three different estuaries located in the Bay of Bengal
(Vedharanyam, Parangipettai and Pichavaram, Tamilnadu, India) for the presence of enzymes and
Objective: Isolation, enzyme screening, antimicrobial activity of Aeromonas hydrophila from spoiled
vegetables and three different estuarine microbial sediment samples for the purpose of biochemical and
Methods: The bioactive compound produced by this strain was purified by using thin-layer chromatography.
Results: The purified isolate of Aeromonas hydrophila strain produces good antimicrobial activity
against Aspergillus niger, Candida albicans, Staphylococcus, Klebsiella and pseudomonas species.
Conclusion: These isolates producing amylase, protease, lipase, and gelatinase enzymes, which are
commercially very important and used in many industries and other biochemical sectors.
