Evaluation of orange peel, an industrial waste, for the production of Aspergillus sojae polygalacturonase
considering both morphology and rheology effects.
According some researches carried out early the cell wall enzyme activity, such as polygalacturonase
and pectinmethylesterase (PRASANNA et al.
During the ripening of the fruits, an increase in the activity of the pectinamylesterase and polygalacturonase
enzymes occurs and the middle lamella disintegration occurs, processes influenced by the ethylene action, with consequent softening of the fruits (KHAN; SINGH, 2007; CANDAN et al.
Optimization of polygalacturonase
using isolated Bacillus subtilis C4 by submerged fermentation.
Kumar YS, Varakumar S and OVS Reddy Production and optimization of polygalacturonase
from mango (Mangifera indica L.
The flesh softening can be attributed to the activity of hydrolytic enzymes such as polygalacturonase
and pectin methyl esterase that promote intense solubilization of pectin, cell wall constituents, resulting in loss of firmness (Silva et al.
2003) and increased methanogenic bacterial count, Lactobacilli and Streptococci and enzymatic yield of polygalacturonase
and pectin esterase (El-Badawi et al.
Apparently, ethylene is regulating the activity of enzymes involved in softening such as polygalacturonase
(Majumder and Mazumdar, 2002).
production by the selected strains was measured quantitatively by DNS method.

as a mechanism of citrus infection and the development of sour rot in fruits by Geotrichum.
