摘要

尽管水生生物膜是一种有效的生物修复剂，但其作为生物监测仪的用途尚未得到广泛的探讨。本研究通过对布兰塔斯河上鳞生物膜的宏基因组学与水质参数和微塑料计数的比较，揭示了鳞生物膜作为生物监测仪的潜力。宏基因组学显示，外缘生物膜以识别和降解微塑料的Exiguobacterium、Rhodobacterium和Rhizobiales为主。首次发现生物膜微生物及其各自的作用与总微塑性计数相对应，而BOD是唯一超越的物理化学参数。因此，鳞生物膜是一种潜在的河流微塑料污染生物监测仪。

Epilithic biofilm as a potential biomonitor for microplastics contamination in Brantas River of Malang City, Indonesia

Despite being an efficient bioremediation agent, aquatic biofilm's usefulness as a biomonitor has not been explored extensively. This study disclosed the potential of epilithic biofilm as biomonitor by comparing its metagenomics with water quality parameters and microplastic count in Brantas River. Metagenomics showed the epilithic biofilm was dominated by Exiguobacterium, which recognizes and degrades microplastics, along with Rhodobacterium and Rhizobiales. For the first time, biofilm microbes and their respective roles were discovered to correspond to the total microplastic counts in comparison with BOD as the only transgressing physicochemical parameter. Thus, epilithic biofilm is a potential biomonitor for riverine microplastic contaminations.
