在这项研究中，我们研究了在两种不同的自养培养介质中培养的普通微藻的室外生产情况：BBM为对照和BBM+海水淡化浓缩液(BBM+DC)在开放式跑道池塘(8m(2))中培养。收集了该菌的生长、生物产量和生化组成等数据。BBM+DC培养的生物量生产力为6.8gm(-2)d(-1)，而BBM对照为8.5gm(-2)d(-1)。藻类主要成分为胞内蛋白(28.6%)，其次是碳水化合物+纤维(26.0%)和脂类(5.0%)。主要脂肪酸为α-亚麻酸(19.5%)、棕榈酸(16.5%)和亚油酸(10.0%)。本研究通过海水淡化废水在藻类规模化生产中的应用，论证了在以DC为基础的替代培养基中培养普通螺旋藻用于海水淡化废水处理的可行性。
In this study, we investigated the outdoor production of a microalga C. vulgaris cultured in two different media under autotrophic cultivation: Bold Basal Medium (BBM) as the control and BBM supplemented with desalination concentrate (BBM + DC) using open raceway ponds (8 m(2)). Data were collected on the growth, biomass productivity and biochemical composition. The culture developed in BBM + DC showed a biomass productivity of 6.8 g m(-2) day(-1), while for the BBM control it was 8.5 g m(-2) day(-1). Intracellular protein was the main algal component (similar to 28.6%), followed by carbohydrate + fiber (similar to 26.0%) and lipids (similar to 5.0%). The predominant fatty acids were mainly alpha-linolenic (similar to 19.5%), palmitic (similar to 16.5%) and linoleic (similar to 10.0%) acids. This study demonstrates the feasibility of culturing C. vulgaris in an alternative medium based on DC in order to valorize the desalination wastewater through its application to algal mass production.
