Influence of environmental conditions on the production of pectinesterase and polygalacturonase byAspergillus niger

Enhanced polygalacturonase production by Aspergillus niger NRRL-364 grown on supplemented citrus pectin

“…All the experiments desciibed so far were performed at 30°C. This temperature was selected based on reported temperatures for optimal enzyme production by Aspergillus genus (Maldonado andCallieri 1989: Bailey 1990). However, experiments were later conducted at various temperatures in order to determine temperature effect on PG production.…”

Characterization of polygalacturonases produced by the endophytic fungus Penicillium brevicompactum in solid state fermentation - SSF

“…The increase in the synthesis of polygalacturonase by adding pectin (Maldonado and Calieri, 1989;Larios, Garcia and Huitron, 1989;Bailey, 1990;Baracat et al, 1991), or galactose (Polizeli, Jorge and Terenzi, 1991), to the growth medium, has been observed with other micro-organisms. This study was performed using galactose and polygalacturonic acid on pectin 2% as carbon sources in order to analyze the biomass, protein and polygalacturonase activity of P. brevicompactum.…”

Production of pectinases by A. niger: influence of fermentation conditions

“…Table 4 showed that PE production slightly increased at about 74 h of fermentation. At pH higher than 5.0, PE production increased with pectin since the synthesis of this enzyme was induced by this substrate (Maldonado and Callieri, 1989;Maldonado et al, 1994).…”

“…The synthesis of pectinases is induced by pectin or for some of its derivatives (Solís Pereira et al, 1993). The cell growth, sporulation and production of the enzymes can be affected by the composition of the medium and fermentation conditions (Maldonado and Callieri, 1989;Costa et al, 2007). Most reported studies are carried out varying one factor at a time while keeping the others at a constant level.…”
