Study of the diversity of molds and their toxicity for systemic and respiratory health in soybean sauce
Journal Title: JOURNAL OF FUNCTIONAL VENTILATION AND PULMONOLOGY - Year 2018, Vol 9, Issue 26
Abstract
Introduction. Aflatoxins are mycotoxins secreted by Aspergillus flavus, which can colonize the respiratory tract and cause fungal rhinosinusitis or bronchopulmonary aspergillosis. A. flavus is the second leading cause of invasive aspergillosis worldwide. Objectives. Objectives of the study was to evaluate the diversity of mold and fungal toxins in some soybean sauce samples collected in Hung Yen induced respiratory and systemic health problem. Methods. Samples were randomly collected in some families with traditional soybean sauce production and some samples were sold on the market in Ban village - Hung Yen town. Microorganisms: fungal isolated from the soybean sauce collected in Ban village - Hung Yen town. Results. The result showed that the moldy colonies were quite diverses, varying in diameter from 4-6 cm; Color of the colonies is varied with major colors such as bright yellow, dark yellow, dark green, blue gray, black, some white spongy colonies. The number of molds ranges from 104 to 106 cells/mL. With the same samples collected on the market, the isolates obtained were mostly bacterial, with very few fungi grown and grown on isolated media. After separating the colonies and purifying, we selected 12 mold varieties representing different color groups for further study. Conclusion. Fungus are quite diverse mainly in Aspergillus and Penicillium. Of the nine strains of Aspergillus, six species are closely related to Aspergillus flavus and Aspergillus oryzae.
