Sustainable energy transition has brought the attention towards microalgae utilization as potential feedstock due to its tremendous capabilities over its predecessors for generating more energy with reduced carbon footprint. However, the commercialization of microalgae feedstock remains debatable due to the various factors and considerations taken into scaling-up the conventional microalgal upstream processes. This review provides a state-of-the-art assessment over the recent developments of available and existing microalgal upstream cultivation systems catered for maximum biomass production. The key growth parameters and main cultivation modes necessary for optimized microalgal growth conditions along with the fundamental aspects were also reviewed and evaluated comprehensively. In addition, the advancements and strategies towards potential scale-up of the microalgal cultivation technologies were highlighted to provide insights for further development into the upstream processes aimed at sustainable circular bioeconomy.
可持续能源转型引起了人们对微藻利用的关注，因为它在产生更多能源的同时，减少了碳足迹，具有比前代产品更大的潜力。然而，由于在常规微藻上游工艺放大过程中需要考虑各种因素，微藻原料的商业化仍然存在争议。本综述对现有的和现有的微藻上游培养系统的最新进展进行了评估，以实现最大生物质产量。还对优化微藻生长条件所需的关键生长参数和主要培养模式以及基本方面进行了全面的综述和评价。此外，还强调了微藻培养技术潜在放大的进展和策略，为进一步发展可持续循环生物经济的上游工艺提供了见解。
