摘要

本文介绍了绿微藻糖嗜绿藻(Chloroidium saccharophilum, Trebouxiophyceae)的研究历史，其研究历史可追溯到100多年前。考虑了其种内变异性的问题。我们还研究了从贝加尔湖东南岸(俄罗斯布里亚特共和国)一个小水坑中分离的saccharophilum irk - a230菌株。光镜和电子显微镜以及分子系统发育方法确定了菌株的物种身份。藻类细胞呈椭球状，有顶叶绿体和可见的淀粉鞘类蛋白;偶数或奇数的等或不等的常孢子繁殖;形成球形细胞的能力;在古老的非异养培养中积累黄色色素。我们获得的数据补充了物种特征及其生物学和地理学。提供了C. saccharophilum的修正描述。

Chloroidium saccharophilum (Chlorophyta) from the Lake Baikal shore (Republic of Buryatia, Russia)

The article provides information about green microalga Chloroidium saccharophilum (Trebouxiophyceae) whose history of study dates back to more than 100 years. The issues of its intraspecific variability are considered. We also studied the strain of C. saccharophilum IRK–A 230 isolated from a small puddle on the southeastern shore of Lake Baikal (Republic of Buryatia, Russia). Light and electron microscopy and molecular phylogeny methods establish the species identity of the strain. The alga has an ellipsoidal cell shape, parietal chloroplast and visible pyrenoid with starch sheath; reproduction by equal and unequal autospores in even and odd numbers; the ability to form spherical cells; and accumulated yellow pigments in old non-heterotrophic cultures. The data obtained by us complement the species characteristics, and its biology and geography. The amended description of C. saccharophilum is provided.

期刊介绍： The Journal is one of the scientific periodicals of the Komarov Botanical Institute (at present belonging to the Russian Academy of Sciences), founded as the garden of medicinal plants by Peter the Great in February 1714. The Journal under the name Novosti sistematiki nizshikh rastenii was founded in 1964 by the botanists of the Komarov Botanical Institute, St. Petersburg (formerly Leningrad). It represents a continuation of Botanicheskie materialy Instituta Sporovykh Rastenii Glavnogo Botanicheskogo Sada RS FSR, Petrograd, vol. 1–4(7), 1922–1926; Botanicheskie materialy otdela sporovyh rastenii Botanicheskogo Instituta imeni V. L. Komarova Akademii Nauk SSSR, Moscow, Leningrad, vol. 5(4/6)–5(10/12), 1940–1945; vol. 6(7/12)–16, 1950–1963, preceded by Botanicheskie materialy Otdela sporvykh rastenii Botanicheskogo Instituta Akademii Nauk SSSR, Moscow, Leningrad vol. 6(1/6), 1949. The Journal publishes original papers on taxonomy, systematics and biodiversity of algae, fungi, lichens and bryophytes.
