从日本富山县的富山湾分离到一株细菌菌株Myt-1。Myt-1能够将各种海藻物种的菌体还原成单细胞碎屑颗粒。16 S rDNA同源性搜索显示，Myt-1的最近亲缘关系是降解食蟹猴2-40（CP 000282; 100%相似性），它首先在美国弗吉尼亚州的切萨皮克湾分离到。Myt-1菌株能降解10种以上的多糖，几乎所有的多糖都能被S.降解物2-40。通过海藻酸酶基因DNA序列同源性分析、DNA-DNA同源性分析和多糖酶谱分析，初步认为Myt-1是噬藻藻属的一个新种。因此，Myt-1只是该属中的第二个种，自1988年以来，该属仅包含一个菌株和一个种，并暂时被命名为食蚜蝇Myt-1。Myt-1在减少海藻废弃物的体积和从海藻基质生产功能材料方面具有相当大的潜力。
A bacterial strain, Myt-1, was isolated in Toyama Bay in Toyama Prefecture, Japan. Myt-1 was capable of reducing the thalli of various seaweed species to single cell detritus particles. A 16S rDNA homology search revealed that the closest relative of Myt-1 was Saccharophagus degradans 2–40 (CP000282; 100% similarity), which was first isolated in Chesapeake Bay in Virginia, USA. The Myt-1 strain was capable of degrading more than 10 polysaccharides, almost all of which were also degraded by S. degradans 2–40. Analyses of alginase gene DNA sequence homology, DNA–DNA homology, and zymogram analysis of obtained polysaccharidases suggested that Myt-1 was a new species of Saccharophagus. Thus, Myt-1 is only the second species in this genus, which has contained only one strain and species since 1988, and was tentatively designated Saccharophagus sp. Myt-1. Myt-1 has considerable potential for reducing the volume of seaweed wastes, and for producing functional materials from seaweed substrate.
