Physiological metal uptake by Nostoc punctiforme

BioMetals, 2012
Trace metals are required for many cellular processes. The acquisition of trace elements from the environment includes a rapid adsorption of metals to the cell surface, followed by a slower internalization. We investigated the uptake of the trace elements Co(2+), Cu(2+), Mn(2+), Ni(2+), and Zn(2+) and the non-essential divalent cation Cd(2+) in the ...

Necessity of Boron for Nostoc muscorum

Nature, 1952
THERE are very few reports on the necessity of boron for the growth of lower plants. Koffler et al.1 found that borax increased the penicillin yields of submerged corn-steep cultures of Penicillium as well as cultures of Penicillium in synthetic medium. No definite requirement by algae for boron has yet been shown2.

Unusual reversible elastomeric gels from Nostoc commune

International Journal of Biological Macromolecules, 2017
Nostoc 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.

Mixotrophic Growth of Nostoc 268

1984
In 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

2018
Although 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 ...

Nostoc PCC 73102 and H2

2007
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 ...
