Lactose catabolism in H. jecorina is initiated by the extracellular hydrolysis of lactose in its monomers D-galactose and D-glucose, mainly by the BGA1 β-galactosidase and also by a second, not yet identified and mainly cell wall-bound, β-galactosidase [ 74].
The cell wall fraction contained mainly cell walls but also a few structural components such as fibres in the bark when observed by microscopy.
As storage tissue, the mature endosperm accumulates nutrient reserves (mainly cell-wall polysaccharides, sucrose, proteins and oils) which are mobilized by the embryo during germination and seedling growth.
The ILs mainly action cell wall components, dissolve them in turn, increase the cell wall permeability, resulting in higher yield of the effective constituents [24].
Despite this fact, as the key reason of the "killing action" of high pressures on microorganisms is recognized the action on more complex structure, mainly the cell wall.
Enzymatic hydrolysis of lignocellulosic biomass (mainly plant cell walls) is a critical process for biofuel production.
The central cavity, or lumen, of straw is lined by pith that covers parenchyma cells and that possesses mainly primary cell walls.
Cellulose accumulates mainly in cell walls representing a primary target when an additional carbon source is required in symbiotic associations of algae/cyanobacteria with other organisms [ 14].
Leaf apoplast proteins were mainly associated with cell wall metabolism (most abundant), stress/defense, and proteolysis, whereas stem apoplast proteins were mainly associated with stress/defense (most abundant), cell wall metabolism, and carbohydrate metabolism.
Mannanoligosaccharides (MOS) are mainly isolated from cell wall fragments of yeast.
Invertase secreted from S. cerevisiae cells resides mainly in the cell wall to perform its physiological function, cleavage of sucrose molecules diffusible into the cell wall (Nam et al. 1993).
