Marine-derived enzymes have recently gained attention particularly for industrial applications. Cellulose-degrading enzymes are among leading biocatalysts with potential utility in biorefineries. This review presents an account of the cellulase production by marine sources from microorganisms including bacteria, yeasts, and molds to marine invertebrates such as protist, rotifer, mollusks, arthropods, and echinoderms. Cellulose-degrading ability of marine invertebrates is attributed to the production of endogenous cellulases and activities by the symbionts. Specialized environments in marine including estuaries and mangroves are rich in lignocellulosic biomass and hence provide a feeding ground for cellulose digesters. Since cellulosic biomass is considered chemical and energy feedstock, therefore, cellulases with the ability to work under extreme environment are much needed to fulfill the demand of modern biotechnological industries. The review also discusses physicochemical parameters of marine-derived cellulases.

Key Points:
• Cellulolytic ability is widely distributed amongst marine organisms, yet very few have been studied for their biotechnological potential
• Cellulase from marine organisms has been demonstrated as a successful agent in degradation of seaweed processing waste to low molecular fragments
• Marine derived cellulases can find their application in green processes
• Cellulases from marine sources exhibit high specific activity, thermostability, and other important biochemical properties and hence can contend well with the enzymes from terrestrial sources.

海洋纤维素分解酶及其潜在应用概述。

海洋来源的酶最近已引起人们的关注,特别是在工业应用中。纤维素降解酶是主要的生物催化剂之一,在生物精炼厂具有潜在的用途。这篇综述介绍了海洋来源从包括细菌,酵母和霉菌在内的微生物到海洋无脊椎动物(例如原生生物,轮虫,软体动物,节肢动物和棘皮动物)产生的纤维素酶。海洋无脊椎动物的纤维素降解能力归因于内生纤维素酶的产生和共生体的活性。海洋中包括河口和红树林的特殊环境富含木质纤维素生物质,因此为纤维素消化池提供了觅食地。由于纤维素生物质被视为化学和能源原料,因此,为了满足现代生物技术产业的需求,非常需要具有在极端环境下工作的能力的纤维素酶。审查还讨论了海洋来源的纤维素酶的理化参数。

关键点
•纤维素分解能力在海洋生物中广泛分布,但对其生物技术潜力的研究很少
•来自海洋生物的纤维素酶已被证明是将海藻加工废料降解为低分子碎片的成功试剂
•海洋衍生的纤维素酶可以在绿色工艺中找到其应用
•海洋来源的纤维素酶具有较高的比活,热稳定性和其他重要的生化特性,因此可以与陆地来源的酶很好地竞争。
