Abstract

ABSTRACT POME is an excellent cultivation medium for the production of microalgae because it includes high macro and micronutrients. Nevertheless, microalga cultivation is laborious to maintain under outdoor condition. The aim of this reseasch was to evaluate the potency of co-cultivation strategy to improve growth and lipid production of mixed algae when growing on POME under dynamic outdoor condition. Cultivation was done in outdoor condition by comparing synthetic medium and POME medium, and optimizing the enviromental and nutritional conditions by using Box-behnken response surface methodology (RSM). Results showed that high growth rate (0.35/d) and lipid (40%) were achieved when 75% POME fraction, 30 PSU salinity, and 450 mg/L urea were used. The increasing POME fraction and urea addition enhanced SFA formation to MUFA and PUFA in the fatty acid profiles. We conclude that co-cultivation strategy on POME could promote growth rate and lipid production of mixed algae under outdoor condition.

室外条件下棕榈油厂废水微藻共生培养产脂研究

POME含有较高的宏量和微量元素，是生产微藻的优良培养基。然而，在室外条件下，微藻的培养是费力的。本研究的目的是评估在动态室外条件下，在POME上生长时，共培养策略对混合藻类生长和脂质产生的促进作用。在室外条件下，通过对比合成培养基和POME培养基进行培养，并采用Box-behnken响应面法(RSM)优化环境和营养条件。结果表明，当POME浓度为75%、PSU浓度为30、尿素浓度为450 mg/L时，可获得较高的生长速率(0.35/d)和脂质(40%)。POME馏分和尿素添加量的增加促进了脂肪酸谱中SFA到MUFA和PUFA的形成。综上所述，在室外条件下，POME共培养策略可以提高混合藻的生长速度和产脂量。

期刊介绍： Environmental Pollutants & Bioavailability is a peer-reviewed open access forum for insights on the chemical aspects of pollutants in the environment and biota, and their impacts on the uptake of the substances by living organisms. Topics include the occurrence, distribution, transport, transformation, transfer, fate, and effects of environmental pollutants, as well as their impact on living organisms. Substances of interests include heavy metals, persistent organic pollutants, and emerging contaminants, such as engineered nanomaterials, as well as pharmaceuticals and personal-care products as pollutants.
