Moisture influence on fungal growth in black pepper

The moisture content at which fungal growth proliferated on black pepper was determined at different relative humidities. At 18% moisture content, fungal growth occurred but this was not recorded at the next lower moisture content of 13.9%. Microscopic examination of infected fresh green pepper showed the presence of species of Trichothecium, Colletotrichum and Fusarium. In black pepper, species of Aspergilli and Penicillium were observed.
