STUDIES ON THE USE OF LACTIC ACID BACTERIA FOR THE BIO-CONTROL OF FOOD SPOILAGE MYCOTOXIGENIC FILAMENTOUS FUNGAI

Abstract: In recent years, fungal spoilage has been documented as an important issue for the agriculture-based food industries, leading to food sensory defects, food waste, economic losses and public health concern through the production of mycotoxins especially in the developing countries. As such, there has been a corresponding search for safer natural products and the demand for less processed and chemically treated foods. The aim of this study was therefore to evaluate the in vitro antifungal effect of some strains of Lactic Acid Bacteria (LAB). Some spontaneously fermented cow milk product was screened for potential LAB using pour plating technique using Man Rogosa Sharpe (MRS) agar incubated at 37°C in anaerobic conditions. Afterwards, the cell-free supernatant (CFS) of the pure, promising LAB were recovered by centrifugation of broth-grown cultures to determine its antifungal activity using halo diffusion agar test. The minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) were determined for each LAB isolate. The CFS of the two pure LAB strains was used respectively as an in vitro natural biocontrol agent against Aspergillus niger (FS06) and Fusarium avenaceum (FS43). L. casei LG4 showed the highest antifungal effect against all essayed strains, while L. plantarum LG7 showed less effect. The results suggest that the application of the CFS from these strains in food could reduce the postharvest spoilage of foods and it thus offers promising steps for the development of biocontrol of fruits (oranges).

Keywords: fungal spoilage, agriculture-based food industries, public health, Lactic Acid Bacteria (LAB).
