The increasing interest in the preservation of the environment and the health of consumers is changing production methods and food consumption habits. Functional foods are increasingly demanded by consumers because they contain bioactive compounds involved in health protection. In this sense biofertilization using plant probiotics is a reliable alternative to the use of chemical fertilizers, but there are few studies about the effects of plant probiotics on the yield of functional fruits and, especially, on the content of bioactive compounds. In the present work we reported that a strain of genus Phyllobacterium able to produce biofilms and to colonize strawberry roots is able to increase the yield and quality of strawberry plants. In addition, the fruits from plants inoculated with this strain have significantly higher content in vitamin C, one of the most interesting bioactive compounds in strawberries. Therefore the use of selected plant probiotics benefits the environment and human health without agronomical losses, allowing the production of highly functional foods.
人们对环境保护和消费者健康的关注度日益提高，这正在改变生产方式和食品消费习惯。功能性食品越来越受到消费者的青睐，因为它们含有参与健康保护的生物活性化合物。从这个意义上说，使用植物益生菌进行生物施肥是一种可靠的替代化肥的方法，但关于植物益生菌对功能性水果产量，尤其是对生物活性化合物含量影响的研究却很少。在本研究中，我们报道了一种能够产生生物膜并在草莓根部定殖的叶杆菌属菌株，它能够提高草莓植株的产量和品质。此外，接种该菌株的植株所结的果实中维生素C的含量显著更高，维生素C是草莓中最有趣的生物活性化合物之一。因此，使用选定的植物益生菌对环境和人类健康有益，且不会造成农业损失，从而能够生产出高功能性食品。
