Abstract
A thermotolerant and rapidly-growing yeast for production of single cell protein from palm oil was isolated and identified as Candida tropicalis F129. The optimum temperature and pH for growth were 38°C and 6.0, respectively. The yeast grew with a high specific growth rate, of 0.92/h in 2% (v/v) palm oil medium, compared with other oil-assimilating yeasts or hydrocarbon-utilizing thermophilic yeasts. The overall cell yield was 1.01 g dry cells/g palm oil after 12 h.
