Note

Daily aeration periods of 4, 6, 12, and 24 h were examined for their effects on productivity of Gracilaria sp. Strain G-16 and on resultant agar quality. There were significant effects on biomass productivity, with decreases from 22 to 12 g.m2.d−1 at decreases from 24 h to 4 h of daily aeration, respectively. However, there were no effects of daily aeration periods on agar content, gel strength, or gelling and melting temperatures, suggesting that daily aeration period can be adjusted to provide maximum economic return based on seaweed and agar productivity. An analysis of total revenue, marginal revenue and aeration costs indicated that the most cost-effective aeration period was 11 h/day.
