ABSTRACT Streptomyces bacteria use volatile compounds for a range of functions, including communication and to kill competing species. We previously showed that the wild-type Streptomyces venezuelae strain ISP5230 produces the alkaline volatile trimethylamine (TMA), which can completely rescue the m...

The kiwifruit trees (Actinidia deliciosa cv. Bruno) were sprayed with 5 mmol L–1 oxalic acid (OA) or water (as control) at 130, 137 or 144 d after full-blossom, and then the fruit were harvested at commercial maturity and stored at room temperature (20±1)°C for 13 d. The effect of pre-harvest sprayi...
