摘要

可可是一种具有经济价值的种植商品,但其种植往往面临着棕榈疫霉带来的巨大挑战。植物酵母在保护植物表面免受病原体感染方面发挥着重要作用。这项研究的目的是评估可可果实上发现的植生酵母菌的多样性,并确定它们是棕榈疫霉的生物控制剂。方法包括从幼嫩、老化和腐烂的可可荚果中分离酵母菌,并将其作为棕榈疫霉的拮抗剂进行测试。这项研究的结果发现,有 8 种酵母分离物对棕榈疫霉的生长有显著抑制作用。这些分离物跨越六个属,包括德巴里酵母菌属(Debaryomyces sp.)、麦兹尼科酵母菌属(Metschnikowia sp.)、酿酒酵母菌属(Zygosaccharomyces sp.)、念珠菌属(Candida sp.)、威克汉酵母菌属(Wickerhamomyces sp.)和隐球菌属(Cryptococcus sp.)。念珠菌属 2 和威克汉酵母菌属(Wickerhamomyces sp.)是特别有潜力的菌种,具有持续的抗性抑制作用,抑制百分比分别达到 36.26%(10.8 毫米)和 34.44%(9.6 毫米)。

Phylloplane Yeasts on Cocoa and Their Abilities to Inhibit Phytophthora palmivora In Vitro
Cocoa is an economically valuable plantation commodity, but its cultivation often faces a significant challenge, which is caused by the Phytophthora palmivora. Phylloplane yeast has an important role in protecting plant surfaces from pathogen infection. The aim of the study was to assess the diversity of phylloplane yeasts found on cocoa fruits, and determine them as biological control agents for P. palmivora. The metode include isolating yeasts from young, old and rotten cocoa pods and testing them as antagonists against P. palmivora. The findings of this study yielded eight yeast isolates that were significant in inhibiting the growth of P. palmivora. These isolates spanned across six genera, including Debaryomyces sp., Metschnikowia sp., Zygosaccharomyces sp., Candida sp., Wickerhamomyces sp., and Cryptococcus sp. Candida sp.2 and Wickerhamomyces sp. as particularly promising species species that had a consistently resistant level of inhibitory effect, achieved percentage inhibition of 36.26% (10.8 mm) and 34.44% (9.6 mm), respectively.
