Abstract
A marine yeast, strain MM313 was isolated from a marine sediment sample at depth of 1120 m. The organism was identified as a Candida sp. MM313. The yeast was able to utilize n-paraffin, n-C10 to n-C20. Regardless of its origin, the organism grew in a medium prepared with fresh water. However, the cell yield increased with increasing concentration of each salt in sea water in the medium and reached a maximum value at the concentration of 75%. The cultivation temperature for the maximum rate of growth and that for the maximum level of growth were 28° and 10°C, respectively. Several cultural conditions were investigated. The cell yields to n-paraffins were about 85% at 15°C after 4 days and 56% at 28°C after 3 days under optimal conditions.
