Abstract

The common microbiota of strawberry fruits was characterized by sequencing with a special focus on spoilage organisms. A comprehensive understanding of the microbiota of strawberries might reduce food loss by spoilage and facilitate the manufacture of safe products. Altogether, 19 samples of fresh strawberries from Spain, Germany, and Austria were collected and analyzed by Illumina amplicon sequencing. A shared microbiota of the investigated strawberries is represented by 16 bacterial and 14 fungal genera. Potential spoilage organisms including the genera Bacillus, Cladosporium, and Botrytis (in 95% of samples) were identified as part of this common microbiota of the analyzed strawberries. These spoilage organisms might pose a particular risk to pasteurized strawberry products by their ability to form spores. In this context, Cladosporium herbarum and Botrytis caroliniana could be of particular importance. Human pathogens already known to be associated with foodborne illness caused by strawberries were not identified in the microbiota of investigated strawberries. The present study underlines the importance of understanding the microbiota of strawberry fruits to produce safe and shelf-stable food from raw strawberries.

期刊介绍： LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
