Image 1. Aspergillus carbonarius (JS742).

A - Colony surface on CYA media (7 days, 25°C); B - Colony reverse on MEA media (7 days, 25°C);

C - Conidial head splitting into diverging columns and producing heavy exudates when mature;

D - Conidial head radiate and biseriate; E - SEM of conidial head, (Bar = 20µm); F - Conidia globose, rough and spikes (Bar = 5µm).

Image 2. Aspergillus sulphureus (JS500).

A - Colony surface on CYA25 media (7 days, 25°C); B - Colony surface on CYA37 media (7 days, 37°C);

C - Colony surface on MEA(7 days, 25°C); D - Conidial heads white;

E - Uniseriate conidial head (Bar = 50µm); F - Conidia (Bar = 10µm).\

Figure 1. HPLC analyses of crude extracts of

(A) - A. sulphureus (JS500) grown on CYB at the top; (B) - A. carbonarius (742);

(C) - The following metabolite (ochratoxin) produced by this isolate can be

identified using retention times and comparing UV spectra from analyses of standard Ohcratoxin A.
