Short peptides secreted by Bacillus subtilis inhibit the growth of mold on fresh-cut pumpkin (Cucurbita pepo).

Background: This study investigates the efficacy of short peptides secreted by Bacillus subtilis for fungal inhibition in fresh-cut pumpkin and for maintaining its shelf life.

Results: Low-molecular-weight filtrate (LC < 1000 Da) of B. subtilis culture (BC) significantly lowered the total number of molds on fresh-cut pumpkin compared with the untreated control and a BC group after storage.

High-cell-density culture enhances the antimicrobial and freshness effects of Bacillus subtilis S1702 on table grapes (Vitis vinifera cv. Kyoho).

This study investigated the effects of Bacillus subtilis grown in high-cell-density culture (HC) on mold growth suppression and postharvest quality improvement in Kyoho grapes. The HC supernatant (HS) of B. subtilis was more potent than the conventional B.
