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 ...

Tendon’s ultrastructure [PDF]

Muscle Ligaments and Tendons Journal, 2013
The structure of a tendon is an important example of complexity of ECM three-dimensional organization. The extracellular matrix (ECM) is a macromolecular network with both structural and regulatory functions. ECM components belong to four major types of macromolecules: the collagens, elastin, proteoglycans, and noncollagenous glycoproteins. Tendons are

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 ...

Ultrastructural Immunochemistry [PDF]

Cold Spring Harbor Protocols, 2008
INTRODUCTIONThe use of colloidal gold technology was undoubtedly the most significant event in the development of immunochemistry. Gold particles are particularly useful for transmission electron microscopy (TEM) studies, because they scatter electrons strongly and even small particles are clearly visible under the electron microscope.

Is a High Abundance of Spring Diatoms in the Photic Zone of Lake Baikal in July 2019 Due to an Upwelling Event?

Diversity, 2021
A high abundance of planktonic microalgae is typically thought to be related to their ‘bloom’, that is, to active population growth. Diatom blooms in the photic zone of Lake Baikal generally occur during hydrological spring (April–June); when the summer ...

Lipid and Fatty Acids Accumulation Features of Entomoneis cf. paludosa during Exponential and Stationary Growth Phases in Laboratory Culture

Diversity, 2021
Diatoms are capable of accumulating substantial amounts of triacylglycerides in their cells, which differ in the composition of fatty acids depending on the conditions of cultivation, making them attractive subjects in biotechnology. In the present study,

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 ...

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]

, 2020
Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...
