3.5. Antimicrobial activity
Among the tested microorganisms, only S. aureus ATCC 29213 was inhibited by the crude extracts of camu-camu powders (Table 4). The extracts of freeze dried powder and spouted bed powders were classified as active and partially active, respectively. Similar results were found by Myoda et al. (2010) with methanolic extracts of seed and peel of camu-camu against S. aureus at 5 mg/mL. Other extracts such as those obtained from pericarp of P. granatum also presented activity against S. aureus (Pradeep, Manojbabu, & Palaniswamy, 2008).
