Increasing lipid production from AP1 in molasses substrate using sequencing batch method.

Yeasts are considered potential lipid producers to substitute oil-producing plants. Previous study succeeded in isolating AP1 from Indonesia which was able to accumulate 19% lipid. The strain, however, was not optimized for high cell density growth which is required for industry-level.

Genetic Diversity of from in Java Island Based on Ribosomal Regions ITS1/ITS2 and D1/D2.

is commonly found as amylolytic fungi in fermentation. However, its diversity is rarely reported despite being often used for food production in Southeast Asia. This research aims to analyze the genetic diversity and the distribution pattern of .

Process Intensification of Enzymatic Fatty Acid Butyl Ester Synthesis Using a Continuous Centrifugal Contactor Separator.

Fatty acid butyl esters were synthesized from sunflower oil with 1-butanol using a homogeneous lipase in a biphasic organic (triglyceride, 1-butanol, hexane)- water (with enzyme) system in a continuous setup consisting of a cascade of a stirred tank reactor and a continuous centrifugal contactor separator (CCCS), the latter being used for integrated reaction and liquid-liquid separation. A fatty acid butyl ester yield up to 93% was obtained in the cascade when operated in a once-through mode. The cascade was run for 8 h without operational issues.
