Immunoactive polysaccharides produced by heterotrophic mutant of green microalga Parachlorella kessleri HY1 (Chlorellaceae)

Carbohydrate Polymers, 2020
Hot water extract from biomass of heterotrophic mutant green alga Parachlorella kessleri HY1 (Chlorellaceae) was deproteinised, and three polysaccharidic fractions were obtained by preparative chromatography. The low-molecular fraction (1.5 × 104g mol-1) was defined mainly as branched O-2-β-xylo-(1→3)-β-galactofuranan where xylose is partially ...

POLYPHYLETIC ORIGIN OF THE DICTYOSPHAERIUM MORPHOTYPE WITHIN CHLORELLACEAE (TREBOUXIOPHYCEAE)1

open access: closedJournal of Phycology, 2010
The green algal Dictyosphaerium morphotype is characterized by spherical or oval cells connected by gelatinized strands to microscopic colonies, which are covered by prominent mucilaginous envelopes. Combined SSU and ITS rRNA gene sequence analyses revealed that this morphotype evolved independently both in the Chlorella and Parachlorella clades of the

A new genus of soil green microalgae Edaphochloris gen. nov. (Chlorellaceae, Trebouxiophyceae)

Issues of modern algology (Вопросы современной альгологии), 2022
The problem of studying the species diversity of small single-celled green coccoid microalgae (Chlorophyta) is still relevant, since their simple and uniform cellular morphology makes it extremely difficult to correctly identify them. It is now generally accepted that the best approach for creating a new, more natural classification of “little green ...

Effect of altered nitrogen partial pressure on Chlorellaceae for spaceflight applications

Algal Research, 2019
Abstract Algal-based photobioreactors offer a promising bioregenerative technology that can perform the functions of air revitalization, water recycling, and food production in a human spacecraft life support system. In order to assess their performance in this context, this study exposed a non-axenic green algal culture (Chlorellacea) to an ...

New species Micractinium kostikovii (Chlorellaceae, Trebouxiophyceae) from Russia

Phycological Research, 2021
SUMMARYCorrectly identifying species of Chlorella‐like microalgae is difficult because of their morphological simplicity and high phenotypic plasticity. The use of molecular tools has revolutionized research on algal diversity, enabling such advances as the discovery of numerous new taxa. This article presents the results of a study of strains that are

Late type of daughter cell wall synthesis in one of the Chlorellaceae, Parachlorella kessleri (Chlorophyta, Trebouxiophyceae)

Planta, 2005
Autosporulation is a common mode of propagation for unicellular algae. Autospore-forming species of Chlorellaceae, Chlorella vulgaris Beijerinck, C. sorokiniana Shihira et Krauss, C. lobophora Andreyeva, and Parachlorella kessleri (Fott et Nováková) Krienitz et al. have glucosamine as the main constituent of their rigid cell wall.
