Overview of 38 bacterial species identified by MALDI-TOF analysis from macroplastics and seawater samples of the lagoon of Toliara, Madagascar

identifying bacteria from various environmental compartments is a common task in microbiology (e.g. infectiology, detection of water- and foodborne pathogens). matrix-assisted laser desorption ionization time-of-flight mass spectrometry (maldi-tof ms) is a rapid and cost-effective method for bacterial species characterization. most of the studies are focused on clinical isolates, but the appeal of this method is growing in environmental science. here, we used maldi-tof ms as a screening tool to identify free living and plastic-associated bacteria of the lagoon of toliara. extracted macroplastic-associated bacteria have been cultured on different selective media and then identified as a set of 201 isolates by maldi-tof. the published dataset will provide insight into the pathobiome associated with floating plastic litter and help evaluate human and animal health risks caused by emerging and well-known pathogens species.

在微生物学领域，诸如感染病学、水生及食源性病原体检测等，识别不同环境组成部分中的细菌是一项常规任务。基质辅助激光解吸电离飞行时间质谱法（maldi-tof ms）作为一种快速且经济有效的细菌物种鉴定方法，其应用日益广泛。尽管多数研究集中于临床分离菌株，但该方法在环境科学领域的吸引力正在不断上升。本研究中，我们以maldi-tof ms作为筛查工具，用于识别托利拉湾中的自由生活及塑料关联细菌。从提取的巨塑料关联细菌中，经过不同选择性培养基的培养，经maldi-tof鉴定共获得201个分离株。即将发布的数据库将揭示与漂浮塑料垃圾相关的病原生物群，并有助于评估由新兴和已知病原体物种引起的人类及动物健康风险。
