Therefore, quantitative evaluation of the enzyme activity from the standard curve of galacturonic acid
displayed the maximum enzyme activity among the two strains of Bacillus i.
Polygalacturonase catalyzes the [alpha]-1,4 bonds between adjacent residues of galacturonic acid
(SEYMOUR et al.
The pectic acid fraction contains mainly galacturonic acid
and galactose as well as traces of glucose and arabinose (Reynolds, 2004, Hamman, 2008).
The overall objective of this project is to further establish the value chains based on MCF, arabinose (Ara) and galacturonic acid
Chemicals used were sucrose, galacturonic acid
, and [alpha]-cellulose (Sigma-Aldrich, St.
These are the most abundant acidic functional groups and the adsorption capacity of peels is directly related to the presence of these sites in pectin in the form of galacturonic acid
Xylose, arabinose, and galaturonic acid were revealed as major monosaccharides of insoluble NSP whereas galacturonic acid
, arabinose, and galactose ranged as third highest amounts in soluble NSP.
2001), the enzymatic treatment increases the galacturonic acid
content of the juice.
Lyases catalyze the trans-eliminative cleavage of the galacturonic acid
Uronic acid content in each supernatant was assayed according to Blumenkrantz and Asboe-Hansen (1973) using galacturonic acid
(Sigma) as standard.
Intact citrus pectin molecules are long-chain, branched polysaccharides made from individual galacturonic acid
molecules strung together.
Pectin or other pectic substances are heterogeneous group of high molecular weight, complex acidic structural polysaccharides with a backbone of galacturonic acid
residues linked by [alpha](1-4) linkages (Kashyap et al.
