Cultural characterization and mycotoxin production of nine blue mold Penicillium isolates.
| Species | Host | Source (Location) | Year | Patulin 1 | Citrinin | Back Color |
|---|---|---|---|---|---|---|
| P. carneum G2 | Golden delicious | Pennsylvania | 2011 | +/− | +/− | tan |
| P. paneum G9 | Golden delicious | Pennsylvania | 2011 | +/− | +/− | yellow |
| P. expansum R19 | Red delicious | Pennsylvania | 2011 | + | + | tan |
| P. expansum R21 | Red delicious | Pennsylvania | 2011 | + | − | green |
| P. expansum R27 | Red delicious | Pennsylvania | 2011 | + | + | green |
| P. solitum RS1 | Apple | Oregon | 2011 | − | − | tan |
| P. solitum SA | Peach seed | West Virginia | 2011 | − | − | tan |
| P. solitum NJ1 | - | NRRL, Illinois | 2012 | − | − | tan |
| P. sclerotiorum 113 | Obtained from home living room | New Jersey | 2013 | +/− | +/− | orange |
1 The mycotoxins patulin and citrinin were detected by organic solvent extraction followed by thin layer chromatography (TLC) separation and visualization under UV light at 365 nm wave length; +/−: low level faint band on TLC plate and it is unclear whether the mycotoxin is produced or not; +: mycotoxin present; −: mycotoxin not detected; NRRL = culture collection at National Center for Agricultural Utilization Research located in Peoria, Illinois, USA.
