Highlights
- The 10% v/v bacteriocin supernatant exhibited the best antibacterial activity against Staphylococcus aureus in fruit juices.
- At lower concentrations, the bacteriocin supernatant had little to no negative effect on sensory properties of fruit juices.
- Bacteriocin from Pediococcus pentosaceus IO1 could be used as a biopreservative in fruit juices.

Highlights
- A total of 13 fungal species belonging to 7 genera were isolated from legume samples in Ghana.
- Toxicogenic fungal species belonged to the genera Aspergillus, Fusarium, and Penicillium.
- Low to moderate fungal counts of range 1.83 and 2.84 log CFU/g were recorded.
- Isolated fungi have probability to produce mycotoxins that cause adverse health effects in the consumers.
