Impact of Algicidal Bacillus mycoides on Diatom Ulnaria acus from Lake Baikal

open access: yesDiversity, 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

open access: yesApplied 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]

open access: yesMuscle 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

Ultrastructure of elastofibroma [PDF]

open access: yesCancer, 1977
An elastofibroma from a 69-year-old white man was studied by light and electron microscopy. The lesion was comprised of abundant collagen fibers and numerous randomly disposed masses of amorphous elastinophilic material. Ultrastructurally, this material appeared to be derived from a markedly dense, finely fibrillar precursor secreted by fibroblasts and

Dispersal of Silica-Scaled Chrysophytes in Northern Water Bodies

open access: yesDiversity, 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 ...

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

open access: yesDiversity, 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

open access: yesDiversity, 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

open access: yesDiversity, 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

open access: yesPlants, 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.

On the ultrastructure of hibernoma [PDF]

open access: yesCancer, 1975
An electron-microscopic study of hibernoma and a review of the histogenesis, development, and post-natal structural composition of brown and white adipose tissue are presented. The ultrastructural features of hibernoma include multivacuolated and univacuolated cells containing variable numbers of lipid vacuoles, abundant moderately pleomorphic ...
