近年来，由于化学杀真菌剂对人类健康和环境的影响，在植物病原体的处理过程中减少化学杀真菌剂的使用具有迫切的经济和科学需求。本研究探讨了新型环保型尾脂油和内生芽孢杆菌对草莓采后灰霉病的防治效果。25 μL/mL的植物油对B具有较强的抑菌活性。与对照相比，灰霉病菌Str 5的真菌径向生长（41.3%）和真菌菌落形成单位（28.6%）减少。一株新菌株Bacillussafensis B3具有良好的产几丁质酶（3.69 ± 0.31 U/mL）、水解脂肪酶（10.65 ± 0.51 U/mL）和蛋白酶（13.28 ± 0.65 U/mL）的潜力，这些酶负责水解B。cinerea Str 5细胞壁，从而限制真菌生长。草莓果实活体试验表明，草莓油对草莓病害的防治效果达87.25%，而草莓内生细菌B。safensisB_3降低了86.52%。本研究首次报告了单独应用生物制剂控制植物病原性真菌的效率，因此，鼓励将其作为一种新的创新战略应用于前瞻性农业技术和食品安全。
Recently, there have been urgent economic and scientific demands to decrease the use of chemical fungicides during the treatment of phytopathogens, due to their human health and environmental impacts. This study explored the biocontrol efficacy of novel and eco-friendly preen (uropygial) oil and endophytic Bacillus safensis in managing postharvest Botrytis grey mold in strawberry fruit. The preen oil (25 μL/mL) showed high antifungal activity against B. cinerea Str5 in terms of the reduction in the fungal radial growth (41.3%) and the fungal colony-forming units (28.6%) compared to the control. A new strain of Bacillus safensis B3 had a good potential to produce chitinase enzymes (3.69 ± 0.31 U/mL), hydrolytic lipase (10.65 ± 0.51 U/mL), and protease enzymes (13.28 ± 0.65 U/mL), which are responsible for the hydrolysis of the B. cinerea Str5 cell wall and, consequently, restrict fungal growth. The in vivo experiment on strawberry fruit showed that preen (uropygial) oil reduced the disease severity by 87.25%, while the endophytic bacteria B. safensis B3 reduced it by 86.52%. This study reports the efficiency of individually applied bioagents in the control of phytopathogenic fungi for the first time and, consequently, encourages their application as a new and innovative strategy for prospective agricultural technology and food safety.
