Abstract The basal cell wall structure of yeasts which is responsible for the shape and rigidity of the yeast cell is a β-glucan, containing both β 1,3 and β 1,6 linkages (Phaff, 1963) . During conjugation, two yeast cells of opposite mating type fuse by dissolution of cell wall material between them, leading to a typical dumbbell-shaped zygote ...

Fungal cell wall chitinases and glucanases
Microbiology, 2004The fungal cell wall is a complex structure composed of chitin, glucans and other polymers, and there is evidence of extensive cross-linking between these components. The wall structure is highly dynamic, changing constantly during cell division, growth and morphogenesis.

Glucanase activity in coleoptiles of Avena
Archives of Biochemistry and Biophysics, 1969Abstract The presence of five different β-glucanases has been investigated in coleoptiles of Avena with the use of specific substrates. A high activity of β-1,3-glucanase is found associated with the coleoptiles. With regard to β-1,4-glucanase activity a strong activity of exo -cellulase which splits glucose (or cellobiose) from the end of the ...

Immobilized ?-glucanases and their applications
Biotechnology Letters, 1979A number of β-glucanase active enzyme preparations were successfully immobilized either by adsorption on Duolite S-761 phenol-formaldehyde resin or covalently on silanized Spherosil XOB-075 porous silica beads to obtain remarkably stable active biocatalysts.

[1,3-beta-Glucanases of actinomycetes].
Mikrobiologiia, 1984Different actinomyces species (25 strains) were studied and Actinomyces cellulosae 41 was found to be the most active one in its capacity to cause lysis of Saccharomyces cerevisiae intact cells as well as in the production of 1,3-beta-glucanase. The enzyme preparation containing 1,3-beta-glucanase can be obtained from the filtrate of the actinomycete ...

The Biochemical journal, 1968
1. A number of yeast species were examined for the presence of beta-glucanases. Extracts obtained by cell disruption of Saccharomyces cerevisiae, Fabospora fragilis and Hansenula anomala hydrolysed laminarin and pustulan with the production of glucose. Enzymic activities were also detected in the culture fluids of F. fragilis and H.

β-Glucanases from Pisum sativum
1988Publisher Summary Four distinct β-glucanases have been extracted and purified to near electrophoretic homogeneity from etiolated pea stems. Two endo-l,3-β-D-glucanases are present in buffer extracts, with one concentrated in growing regions and the other in maturing tissues.
