Abstract

Geotrichum citri-aurantii is a main pathogen that causes severe postharvest citrus fruit disease and leads to economic losses. In this work, the antifungal activity of bacillomycin D against G. citri-aurantii FZ2 was investigated. The effectiveness of bacillomycin D on controlling citrus sour rot was also evaluated. The results indicated that bacillomycin D had strong antifungal activity on G. citri-aurantiis growth, and 12.24 μmmol/L of minimal inhibitory concentration (MIC) and 24.48 μmmol/L of minimal fungicidal concentration (MFC) were obtained. Bacillomycin D exerted destructive impacts on G. citri-aurantii mycelia and resulted in damage of cell integrity and increase of membrane permeability. When exposed to 48.96 μmol/L of bacillomycin D and stored the infected citrus fruit at 25 °C for 10 d, the citrus sour rot was completely suppressed. Moreover, bacillomycin D treatment could effectively improve citrus fruit quality and increase the resistance to G. citri-aurantii. Our findings showed that bacillomycin D could be used as a promising fungicide for controlling postharvest citrus sour rot and extending the shelf-life for citrus fruit storage.

期刊介绍： The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
