The present communication deals with the taxonomic enumeration of 23 taxa representing 12 species, 09 varieties, 02 forms of the genus Scenedesmus Meyen of order Chlorococcales from Anjani dam in Erandol Tahsil of Jalgaon district, Maharashtra.
Scenedesmus of Nepal has been studied by Hirano (, ), Hickel (a, b), Nakanishi (), Nakano and Watanabe (), Sahay et al. (), Chaturvedi and Habib (), D as and Verma Author: Shiva Kumar Rai.
The genus Scenedesmus and other allied morphospecies can not only been identified morphologically due to their smaller sizes and phenotypic plasticity. In this study, six Scenedesmus-like species were isolated and investigated from the inland freshwater of Ergene River Basin (Thrace, Turkey).

Abstract. Karyotype structures ofScenedesmus acuminatus (Lagerch.) Chod. andScenedesmus pectinatus Meyen are compared. The karyotype ofS.
acuminatus (n = 5) is described for the first time. It reveals four large metacentric and one large submetacentric chromosomes (4M + 1SM). The established karyotype differences have been helpful in clarifying the taxonomic position of these two by: 2. The genus Scenedesmus was named by Meyen in and was classified into four subgenera in by Cho-dat (Clathrodesmus, Desmodesmus, Euscenedesmus and Rhynchodesmus).
However, a recent taxonomic evaluation by Trainor et al.() has divided it into the spiny genus Desmodesmus and the non-spiny genus Scenedesmus (Lürling ). A phylogenetic study on Scenedesmaceae with the description of a new species of Pectinodesmus and the new genera Verrucodesmus and Chodatodesmus (Chlorophyta, Chlorophyceae).

Introduction. Microalgae are important biological resources with a wide range of biotechnological applications.
Some of them are green microalgae such as Chlorella, Dunaliella and Scenedesmus, the last belonging to Scenedesmaceae which currently include 43 recognized genera [, ].The Scenedesmus Meyen genus is pleomorphic and often overrated .The main morphological characteristics to Cited by: 7.

being a genus. Desmodesmus and Scenedesmus, however, were confirmed as genera belonging to Scenedesmaceae family (Hegewald and Braband, ). Several studies sustain these truths. Systematic studies bear some confusions between Scenedesmus and Desmodesmus, that they share species, but the greater number is given to Scenedesmus.

Meyen () was the first who used the generic name Scenedesmus and hence the genus is called Scenedesmus Meyen. Af. phylogeny, Scenedesmus, taxonomy.
The genus Scenedesmus as described by Meyen () included all autosporic coccal green algae with flat or curved coenobia. Since then about taxa have been described (Hege wald and Silva ).
Chodat () revised the genus and set up subgenera to obtain a better understanding of the taxonomic rela. Recently, various studies have been carried out to suppress phytoplankton blooming in Korea (Shin et al. ; Park and Jun ; Chung et al.
Among the Scenedesmaceae belonging to Chlorophyceae, the most taxa belong to genus Scenedesmus, which is floating, and it usually appears in the eutrophic ponds and lakes (Guiry and Guiry ).Author: Sung Do Bang, Jee Hwan Kim, Byeong Cheol Yim, Ok Min Lee.
Scenedesmus Meyen colony is flat, whereas Coelastrum Näg. is spherical in a morphological point of view.
It was also observed that the two varieties of the genus Scenedesmus Meyen occurred in polluted water bodies, so they are good ecological indicator of water File Size: KB.
