Although biotechnologies for astaxanthin production from Haematococcus pluvialis have been developed for decades and many production facilities have been established throughout the world, the production cost is still high. This paper is to evaluate the current production processes and production facilities, to analyze the R&D strategies for process improvement, and to review the recent research advances shedding light on production cost reduction. With these efforts being made, we intent to conclude that the production cost of astaxanthin from Haematococcus might be substantially reduced to the levels comparable to that of chemical astaxanthin through further R&D and the future research might need to focus on strain selection and improvement, cultivation process optimization, innovation of cultivation methodologies, and revolution of extraction technologies.

尽管已经开发了用于从嗜血红球菌生产虾青素的生物技术数十年，并且在世界各地已经建立了许多生产设施，但是生产成本仍然很高。本文旨在评估当前的生产流程和生产设备，分析用于流程改进的研发策略，并回顾最近的研究进展，这些进展为降低生产成本提供了依据。通过这些努力，我们打算得出以下结论：血球菌中虾青素的生产成本 通过进一步的研发，可能会将其大大降低到与化学虾青素相当的水平，未来的研究可能需要集中在菌株的选择和改良，栽培工艺优化，栽培方法的创新以及提取技术的革命上。
