The feasibility of microalgal biomass as one of the most promising and renewable sources for the production of biofuels is being studied extensively. Microalgal biomass can be cultivated under photoautotrophic, heterotrophic, photoheterotrophic, and mixotrophic cultivation conditions. Photoautotrophic cultivation is the most common way of microalgal biomass production. Under mixotrophic cultivation, microalgae can utilize both organic carbon and CO simultaneously. Mixotrophic cultivation depicts higher biomass productivity as compared to photoautotrophic cultivation. It is evident from the literature that mixotrophic cultivation yields higher quantities of polyunsaturated fatty acids as compared to that photoautotrophic cultivation. In this context, for economical biomass production, the organic carbon of industrial wastewaters can be valorized for the mixotrophic cultivation of microalgae. Following the way, contaminants' load of wastewaters can be reduced while concomitantly producing highly productive microalgal biomass. This review focuses on different aspects covering the sustainable cultivation of different microalgal species in different types of wastewaters.
微藻生物质作为最具潜力的可再生生物燃料生产原料之一，其可行性正在得到广泛研究。微藻生物质可在光合自养、异养、光异养和兼养培养条件下进行培养。光合自养培养是微藻生物质生产最常见的方式。在兼养培养条件下，微藻可以同时利用有机碳和二氧化碳。与光合自养培养相比，兼养培养具有更高的生物质生产力。从文献中可以明显看出，与光合自养培养相比，兼养培养能产生更多数量的多不饱和脂肪酸。在此背景下，为了实现经济的生物质生产，工业废水的有机碳可用于微藻的兼养培养。通过这种方式，在生产高产微藻生物质的同时，可以降低废水的污染物负荷。本综述聚焦于不同类型废水可持续培养不同微藻物种的各个方面。
