Abstract

This paper addresses the modeling of astaxanthin accumulation in the microal-gae Haematococcus pluvialis, a well-known source of natural astaxanthin, under fluctuating environmental conditions. For biomass growth and astaxanthin accumulation first principles models under sufficient nutrient concentration and high incident light exposure are derived. The obtained models are validated using measurement data of an outdoor production plant, and are the basis for implementing an extended Kalman Filter (EKF) for state and unknown reaction rate estimation.

雨竹生产规模养殖中非表征反应的动态建模与评价[j]

本文讨论了在波动的环境条件下虾青素在微藻雨红球菌（一种众所周知的天然虾青素来源）中积累的建模。对于生物量生长和虾青素积累，导出了充足营养浓度和高入射光照射下的第一性原理模型。利用室外生产工厂的测量数据验证了所获得的模型，并为实现用于状态和未知反应速率估计的扩展卡尔曼滤波器（EKF）提供了基础。
