Abstract

Summary Cyanobacteria are widely distributed in all habitats. It makes them an attractive food source for many organisms, including Amoebozoa. We tested 23 strains of naked lobose amoebae belonging to the classes Tubulinea and Discosea for the ability to feed on the filaments of a widely distributed cyanobacterium Oscillatoria sp. Three strains were found to be able to feed on this organism. We documented and described the processes of feeding and discussed different ways that amoebae used to ingest cyanobacterial filaments. The present study experimentally shows that average-sized species of Amoebozoa are able to consume and digest filamentous cyanobacteria and disrupt cyanobacterial biofilm, preventing its formation and adherence to the substrate.

意大利面条的三种吃法:来自两种变形虫谱系的变形虫能够以振荡藻属的蓝藻为食

蓝藻广泛分布于所有栖息地。这使得它们成为许多生物的诱人食物来源，包括变形虫。我们测试了23株属于Tubulinea和Discosea类的裸叶阿米巴变形虫以一种广泛分布的振荡蓝藻的细丝为食的能力。发现有3株能够以这种生物为食。我们记录和描述了喂养过程，并讨论了阿米巴用来摄取蓝藻菌丝的不同方式。本研究实验表明，中等大小的变形虫能够消耗和消化丝状蓝藻，并破坏蓝藻生物膜，阻止其形成和粘附在底物上。

期刊介绍： Protistology is one of the five "organism-oriented" journals for researchers of protistan material. The Journal publishes manuscripts on the whole spectrum of lower Eukaryote cells including protozoans, lower algae and lower fungi. Protistology publishes original papers (experimental and theoretical contributions), full-size reviews, short topical reviews (which are supposed to be somewhat "provocative" for setting up new hypotheses), rapid short communications, book reviews, symposia materials, historical materials, obituary notices on famous scientists, letters to the Editor, comments on and replies to published papers. Chronicles will present information about past and future scientific meetings, conferences, etc. THE PECULIARITIES OF THE JOURNAL - reviews, overviews and theoretical manuscripts on systematics, phylogeny, evolution and ecology of protists are favourably accepted - the manuscripts on multicellular organisms concerning their phylogenetic and taxonomic relationships with protists are also accepted - the size of manuscripts is usually not limited
