Excessive generation of wastewater is a matter of concern around the globe. Wastewater treatment utilizing a microalgae-mediated process is considered an eco-friendly and sustainable method of wastewater treatment. However, low biomass productivity, costly harvesting process, and energy extensive cultivation process are the major bottleneck. The use of the microalgal-bacteria granular consortia (MBGC) process is economic and requires less energy. For efficient utilization of MBGC, knowledge of its structure, composition and interaction are important. Various microscopic, molecular and metabolomics techniques play a significant role in understating consortia structure and interaction between partners. Microalgal-bacteria granular consortia structure is affected by various cultivation parameters like pH, temperature, light intensity, salinity, and the presence of other pollutants in wastewater. In this article, a critical evaluation of recent literature was carried out to develop an understanding related to interaction behavior that can help to engineer consortia having efficient nutrient removal capacity with reduced energy consumption.
全球范围内，废水的过度产生是一个令人关注的问题。利用微藻介导的方法处理废水被认为是一种环保且可持续的废水处理方法。然而，生物量生产力低、昂贵的收获过程以及能源密集型的培养过程是主要的瓶颈。使用微藻-细菌颗粒共生体（MBGC）工艺既经济又节能。为了有效地利用 MBGC，了解其结构、组成和相互作用非常重要。各种微观、分子和代谢组学技术在理解共生体结构和伙伴之间的相互作用方面发挥着重要作用。微藻-细菌颗粒共生体的结构受到各种培养参数的影响，如 pH 值、温度、光照强度、盐度以及废水中其他污染物的存在。本文对最近的文献进行了批判性评估，以了解相关的相互作用行为，这有助于设计具有高效养分去除能力且能耗降低的共生体。
