Abstract

The coconut, Cocos nucifera L., is an abundant and inexpensive commodity in Brazil. An excellent source of carbohydrates and mineral salts, coconut water was tested in this study as an alternative growth medium for Staphylococcus aureus culture. Lyophilized coconut water was hydrated, prefiltered and filter-sterilized with a 0.22 µm Millipore membrane. S. aureus was inoculated in coconut water (M1), coconut water enriched with 1% peptone (M2) and BHI (M3, positive control). After 12 hours of shaking at 140 rpm at 35ºC, bacterial growth was observed. Growth rates were good in M2 and M3, with no statistically significant difference. Thus, coconut water enriched with 1% peptone was shown to be a feasible alternative to commercially available growth media for Staphylococcus aureus culture.
