The original version of this Article contained errors.
In Table 2, the “Yield” and “Purification factor” data for “Ammonium sulfate”, “DEAE-Cellulose” and “Sephadex G-100” were incorrect. The correct and incorrect values appear below.
Incorrect:
Purification steps | Fraction volume (mL) | Protein (mg/mL) | Total protein (mg) | Activity (U/mL) | Total activity (U) | Specific activity (U/mg) | Yield (%) | Purification factor (fold) |
|---|---|---|---|---|---|---|---|---|
Fermentation medium | 1000 | 0.1464 | 146.4 | 0.687 | 687 | 4.692 | 100 | 1 |
Ammonium sulfate | 6.5 | 6.46 | 42 | 17.31 | 112.5 | 2.68 | 0.57 | 16.37 |
DEAE-Cellulose | 15.0 | 0.018 | 0.27 | 18.1 | 271.5 | 1005.55 | 46.493 | 214.4 |
Sephadex G-100 | 10.0 | 0.003 | 0.03 | 5.718 | 57.18 | 1906 | 9.79 | 406.4 |
Correct:
Purification steps | Fraction volume (mL) | Protein (mg/mL) | Total protein (mg) | Activity (U/mL) | Total activity (U) | Specific activity (U/mg) | Yield (%) | Purification factor (fold) |
|---|---|---|---|---|---|---|---|---|
Fermentation medium | 1000 | 0.1464 | 146.4 | 0.687 | 687 | 4.692 | 100 | 1 |
Ammonium sulfate | 6.5 | 6.46 | 42 | 17.31 | 112.5 | 2.68 | 16.37 | 0.57 |
DEAE-Cellulose | 15.0 | 0.018 | 0.27 | 18.1 | 271.5 | 1005.55 | 39.52 | 214.4 |
Sephadex G-100 | 10.0 | 0.003 | 0.03 | 5.718 | 57.18 | 1906 | 8.32 | 406.4 |
In addition, the title of Table 4 was incorrect.
“Yield, clarity, colour and pH of apple, orange, apricot, and peach fruit juices treated with crude pectinase produced by Cladosporium parasphaerospermum AUMC 10865.”
now reads:
“Yield, clarity, colour and pH of apple, orange, apricot, and peach fruit juices treated with pure pectinase produced by Cladosporium parasphaerospermum AUMC 10865.”
Finally, in the Materials and Methods section, under the subheading ‘Isolation and maintenance of Cladosporium strains’, as well as in the Data availability section,
“Nexus file of the sequence alignments for all data sets were uploaded to Tree BASE http://purl.org/phylo/treebase/phylows/study/TB2:S23783 (study no. 29214).”
now reads:
“Nexus file of the sequence alignments for all data sets were uploaded to Tree BASE http://purl.org/phylo/treebase/phylows/study/TB2:S30171?x-access-code=a18696d1afcf659925a63a31c3ebd045&format=html (Study no. 30171).”
The original Article has been corrected.
