Unusual reversible elastomeric gels from Nostoc commune
International Journal of Biological Macromolecules, 2017Nostoc commune cyanobacteria grow in extreme conditions of desiccation and nutrient-poor soils. Their colonies form spherical gelatinous bodies are composed of a variety of polysaccharides that allow them to store water and nutrients. In this paper, we study this type of biological gel that shows characteristics of both chemical and physical gels.

Nostoc interbryum Sant'Anna & al.
Nostoc interbryum Sant’Anna et al. (2007: 96) (Fig. 11D–H). Colonies macroscopically blackish, round to elongated, or amorphous microscopic colonies, 30.06–87.54 μm wide. Trichomes moniliform, densely to sparsely arranged in colonies, flexuous, not branched. Sheath conspicuous, firm, non-lamellated, hyaline to brown. Cells spherical or sub-quadratic, 2.Da Anunciação, Raylane R. +4 more

Mixotrophic Growth of Nostoc 268
1984In recent years, a worldwide interest has arisen in the feasibility of growing microalgal biomass for commercial purposes (Shelef, Soeder 1980). The first steps to carry out microalgal technology at an industrial level have already been taken. In India, a dried preparation of nitrogen-fixing blue-green algal (or cyanobacterial) cultures is supplied to ...

The Nostoc-Gunnera Association
2018Although Nostoc species have established symbiotic relationships across generic lines in more primitive organisms such as lichens, mosses, and cycads, of all angiosperms, only Gunnera is known to establish a symbiotic relationship with Nostoc. Nostoc cells are plentiful in extracellular locations on the Gunnera plant, but they colonize only internal ...

In N2-fixing cyanobacteria, at least three enzymes may be involved in H2 metabolism: (a) nitrogenase, evolving H2 during N2 fixation; (b) an uptake hydrogenase, reutilizing this H2; and (c) a bidirectional (reversible) hydrogenase. Our studies focus on the hydrogen metabolism of the filamentous, heterocystous cyanobacterium Nostoc PCC 73102, a free ...

Results of investigation confirm a possibility of forming construction of artificial microbial culture on the base of blue-green algae Nostoc paludosum. Compatibility of blue-green algae with Rhizobium leguminosarum, Rh. galegae, Agrobacterium radiobacter, Pseudomonas fluorescens and Azospirillum lipoferum is discussed.
