Thirteen novel planctomycetal strains were isolated from five different aquatic sampling locations. These comprise the hydrothermal vent system close to Panarea Island (Italy), a biofilm on the surface of kelp at Monterey Bay (CA, USA), sediment and algae on Mallorca Island (Spain) and Helgoland Island (Germany), as well as a seawater aquarium in Braunschweig, Germany. All strains were shown to belong to the genus Gimesia. Their genomes cover a size range from 7.22 to 8.29 Mb and have a G+C content between 45.1 and 53.7%. All strains are mesophilic (T_opt 26–33 °C) with generation times between 12 and 32 h. Analysis of fatty acids yielded palmitic acid (16:0) and a fatty acid with the equivalent chain length of 15.817 as major compounds. While five of the novel strains belong to the already described species Gimesia maris and Gimesia chilikensis, the other strains belong to novel species, for which we propose the names Gimesia alba (type strain Pan241w^T = DSM 100744^T = LMG 31345^T = CECT 9841^T = VKM B-3430^T), Gimesia algae (type strain Pan161^T = CECT 30192^T = STH00943^T = LMG 29130^T), Gimesia aquarii (type strain V144^T = DSM 101710^T = VKM B-3433^T), Gimesia fumaroli (type strain Enr17^T = DSM 100710^T = VKM B-3429^T) and Gimesia panareensis (type strain Enr10^T = DSM 100416^T = LMG 29082^T).

从五个不同的水生采样地点分离出 13 种新的浮霉菌菌株。其中包括帕纳里亚岛（意大利）附近的热液喷口系统、蒙特利湾（美国加利福尼亚州）海带表面的生物膜、马略卡岛（西班牙）和黑尔戈兰岛（德国）的沉积物和藻类，以及德国布伦瑞克海水水族馆。所有菌株均属于 Gimesia属。它们的基因组大小范围为 7.22 至 8.29 Mb，G+C 含量在 45.1% 至 53.7% 之间。所有菌株均为嗜温（T _opt 26–33 °C），世代时间在 12 至 32 小时之间。脂肪酸分析得到棕榈酸(16:0)和当量链长为15.817的脂肪酸作为主要化合物。虽然其中五个新菌株属于已描述的物种Gimesia maris和Gimesia chilikensis，但其他菌株属于新物种，我们建议将其命名为Gimesia alba（类型菌株 Pan241w ^T  = DSM 100744 ^T  = LMG 31345 ^T  = CECT 9841 ^T  = VKM B-3430 ^T )、Gimesia 藻类（典型菌株 Pan161 ^T  = CECT 30192 ^T = STH00943 ^T  = LMG 29130 ^T）、Gimesia aquarii（典型菌株 V144 ^T  = DSM 101710 ^T  = VKM B-3433 ^T）、Gimesia fumaroli（典型菌株 Enr17 ^T  = DSM 100710 ^T  = VKMB-3429 ^T）和Gimesia panareensis（典型菌株 Enr10 ^T  = DSM 100416 ^T  = LMG 29082 ^T）。STH 编号指的是耶拿微生物资源库 (JMRC)。
