Abstract

In this study, the effects of alginate from Sargassum polycystum molecular reduction by thermal heating on DPPH anti radical scavenging activity were investigated. Raw alginate as the control treatment was heated at 140oC in a laboratory oven for different time courses 1.5, 4.5, and 7.5 hours. The assessment of molecular weight, UV-visible and FT-IR spectroscopic studies were applied. By heat treatment, molecular weight of polymer was decreased in a time-dependent manner, though there is no significant difference between 4.5 h and 7.5 h samples. The UV-visible spectroscopic studies pointed that there was a new absorption band between 250 and 290 nm in alginate heated treatments. The higher antiradical scavenging activity were reached from 1.5 h and 4.5 h treatments (19.83% and 20.07%). Interestingly, the antiradical scavenging activity of the longest heating treatment (7.5 h) was reduced (16.85%), similar to the raw alginate (17.89%). Prolonged heat treatments influenced the antioxidant activity and reduced the ability of donate electrons or hydrogen atoms to inactivate this radical action.

Abstract

N. oculata is commonly used as a natural food in larviculture. Due to the fact on its highly lipid content, N. oculata is recently becoming one of a good candidate for a source of alternative energy. Microalgae utilizes CO2 during photosynthesis. This fact will lead and used this microalgaeas a carbondioxide degradator. Providing of carbon dioxide aeration is expected to increase the rate of growth of N. oculata as well as total lipid production.This research aimed to determine the effect of different periods on carbondioxide aerationon the growth rate and total lipid production in N. oculata culture.The results showed that different time on carbondioxide aeration was significantly different (P < 0.05) on the average growth rate as well as total lipid production. Carbondioxide aeration treatment for 3 minutes have the highest average growth rate which is0,574 doubling/ day. While the average growth rate at treatment aeration for 4 minutes almost equal to the control i.e. 0,484 doubling/ day and 0,462 doubling/ day. The highest percentage of total lipid production has reached in 4 minutes carbondioxide aeration treatment (80.58%-dw). Furthermore, the lipid production on 1 minute, 2 minutes aeration time and control were 65.98%-dw, 65.77%-dw and 64.98%-dw, respectively. The treatment with carbondioxide aeration for 3 min was the lowest (39.72%-dw). Based on these results it can be concluded that carbondioxide aeration for 3 minutes increased the growth rate of N. oculata. However, the incrementon growth ratewere not accompanied withthe incrementon total lipid production.
