Concerns regarding high energy demand and gradual depletion of fossil fuels have attracted the desire of seeking renewable and sustainable alternatives. Similar to but better than the first- and second-generation biomass, algae derived third-generation biorefinery aims to generate value-added products by microbial cell factories and has a great potential due to its abundant, carbohydrate-rich and lignin-lacking properties. However, it is crucial to establish an efficient process with higher competitiveness over the current petroleum industry to effectively utilize algal resources. In this review, we summarize the recent technological advances in maximizing the bioavailability of different algal resources. Following an overview of approaches to enhancing the hydrolytic efficiency, we review prominent opportunities involved in microbial conversion into various value-added products including alcohols, organic acids, biogas and other potential industrial products, and also provide key challenges and trends for future insights into developing biorefineries of marine biomass.
人们对高能量需求和化石燃料逐渐枯竭的担忧，促使人们寻求可再生和可持续的替代品。与第一代和第二代生物质类似但优于它们，藻类衍生的第三代生物炼制旨在通过微生物细胞工厂来生产高附加值产品，由于其丰富、富含碳水化合物和缺乏木质素的特性，具有很大的潜力。然而，建立一个比当前石油工业更具竞争力的高效工艺来有效利用藻类资源是至关重要的。在这篇综述中，我们总结了最近在最大限度提高不同藻类资源生物利用度方面的技术进展。在概述了提高水解效率的方法之后，我们回顾了微生物转化为各种有价值产品的突出机会，包括醇、有机酸、沼气和其他潜在的工业产品，并为未来开发海洋生物质生物炼制厂提供了关键挑战和趋势。
