摘要: The effect of sonication pretreatment condition on Eucheuma cottonii and Gelidium amansii seaweed towards agar extraction wae studied. Four parameters were changed during to investigate the effects yield quality. These include time interval, concentration ratio, frequency, intensity. highest amount extracted from species could be obtained interval 30 min, weight solvent volume ratio 1:20, frequency 35 Hz, power intensity 30%. For species, best also 1:20 water From experiment, significantly influenced properties agar. with autoclaved produced containing less sulfate content, which is an excellent chemical property for gel electrophoresis applications. strength autoclaving both seaweeds, was among those by direct heating, proved that enhance physical
