Cytology and ultrastructure of eustigmatophyceae [PDF]
, 1990 Tvelve-species of the alqa class Eustigmatophyceae were studied by means of light and electron microscopy, with particular reference to structural aspects of the vegetative cells and the flagellar apparatus of the zoospores.

Impact of Algicidal Bacillus mycoides on Diatom Ulnaria acus from Lake Baikal
Diversity, 2021 Algae–bacteria interactions play an important role in water ecosystems. In this work, the BS2-15 algicidal strain was isolated from the bottom sediments of Lake Baikal and identified as Bacillus mycoides on the basis of 16S rDNA sequencing, its described

Elusive Recurrent Bacterial Contamination in a Diatom Culture: A Case Study
Applied Sciences, 2021 In preparation for whole-genome sequencing, the axenic culture for two strains of a freshwater diatom Fragilaria radians were produced. Although their axenicity was controlled for the cultures’ entire lifetime, the published genomic assembly was later ...

Dispersal of Silica-Scaled Chrysophytes in Northern Water Bodies
Diversity, 2021 Silica-scaled chrysophytes have an ancient origin; nowadays they inhabit many northern water bodies. As the territories above the 60th parallel north were under the influence of glaciers during the Late Pleistocene, the local water bodies and their ...

Strategy for the Removal of Satellite Bacteria from the Cultivated Diatom
Diversity, 2020 Multiple ecological and genetic studies of diatom algae require an axenic culture. However, algae-associated bacterial biofilms often form in diatom-produced mucus, both during creation of monoclonal cultures from single cells and during biomass growth ...

Quantification of Protein Uptake by Endocytosis in Carnivorous Nepenthales
Plants, 2023 Carnivorous plants adsorb prey-derived nutrients partly by endocytosis. This study quantifies endocytosis in Drosophyllum lusitanicum, Drosera capensis, Drosera roseana, Dionaea muscipula and Nepenthes × ventrata.
