Values are means ± standard deviation; n = 3; a, b, c, and so on indicated column comparison; A, B, C, and so on indicated line comparison; values followed by the same lowercase letter in superscript on the same line or by the same capital letter in superscript on the same column are not significantly different (p < 0.05) according to Duncan's multiple range test. The emulsion has been obtained by mixing supernatant of culture with refined palm oil.
