Efficient Extraction of Starch from Microalgae Using ...

2013-12-24  To increase the extraction ratio of starch from microalgae for effective conversion of starch into ethanol, the ultra- sonic treatment was attempted using a homogenizer. Figure 2 shows the percentage ratios of amounts of starch and glucose extracted from 2 g of dry microalgae in 20 mL of water by the ultrasonic treatment at various treatment times. At zero treatment time no extraction of starch was observed, but 0.5 min of ultrasonic treatment could extract starch from microalgae. Though 0.5 - 5 min of ultrasonic treatment did not affect starch extraction ratio, i.e. about 18%, beyond 5 min of ultrasonic treat- ment the starch extraction ratio increased significantly with the increase of treatment time and then reached a maximum value, i.e. 40.8%, at 30 min. Since as described above the dry microalgae contains 43.5% starch, 30 min of ultrasonic treatment seems to be enough for starch extraction from microalgae and the extraction ratio of starch
