Alternaria mycotoxins in black rot lesion of tomato fruit: conditions and regulation of their production.

Alternaria is the most common decay organism of postharvest tomato fruit. The prevalent type of decay, black rot lesion, is caused by A. alternata which can invade tomato tissue damaged by sun scald. The main natural toxins produced in rotted tomato are alternariol (AOH), alternariol monomethyl ether (AME) and tenuazonic acid (TA). Altertoxin-I and -II (AT-I and -II), AOH, AME and TA were produced by A. alternata in synthetic medium. Opt. temp. for toxin production by A. alternata IMI 89344 was 28 deg C for AOH and AME, 21 deg for TA and 14 deg for AT-I and -II. A noticeable amount of toxin was produced at 7 deg , which dropped at 35 deg . Significant inhibition of the toxins was attained at 500 p.p.m. cinnamon oil in YES-Czapek's medium and in tomato homogenate.
