Antioxidants prevent ageing and are usually quantified and screened using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. However, this assay cannot be used for salt-containing samples, such as the cell-free supernatants of marine microorganisms that are aggregated under these conditions. Herein, the DPPH solvent (methanol or ethanol) and its water content were optimized to enable the analysis of salt-containing samples, aggregation was observed for alcohol contents of >70%. The water content of methanol influenced the activities of standard antioxidants but did not significantly affect that of the samples. Based on solution stability considerations, 70% aqueous methanol was chosen as the optimal DPPH solvent. The developed method was successfully applied to the cell-free supernatants of marine bacteria (Pseudoalteromonas rubra and Pseudoalteromonas xiamenensis), revealing their high antioxidant activities. Furthermore, it was concluded that this method would be useful for the screening of marine microorganism–derived antioxidants, which also has numerous potential applications, such as salt-fermented foods.

Marine microorganism is one of biologically active potential resources of secondary metabolites. Its potency areso promising that the knowledge of how its secondary metabolite occured need to be studied and collected. Thoseknowledges will enable further study is improving secondary metabolite production in the laboratory. In nature,secondary metabolites synthesis occur when there are effect of both biotic and abiotic factors such as sea waterand microbe symbiosis with other living materials. When this is explained in metabolic pathways, secondarymetabolite synthesis affected by available nutrient and regulated by autoinducer molecules through quorum sensingmechanism
