“…These results were lower than expected according to the potential of LAB TEP6. Another study has reported that this bacterium exerts strong inhibition (100%) on both spore germination and mycelium growth in C. gloeosporioides [7].…”

“…Strain TEP6 was previously isolated from tepache samples and was identified as L. paracasei and was selected for its ability to inhibit the phytopathogenic fungus C. gloeosporioides [7]. The strains were reseeded in MRS agar and a cell suspension was prepared with MRS broth.…”

“…In the last two decades, several studies have demonstrated the ability of LAB to inhibit the growth of fungi that cause food spoilage, as in the case of Penicillium expansum [4] and other phytopathogenic fungi [5,6]. Recently, the isolation of the LAB Lactobacillus paracasei TEP6 from tepache was reported, and it was demonstrated to possess strong antifungal activity against the fungus Colletotrichum gloeosporioides, which causes anthracnose in papaya [7].…”

The present study aimed to evaluate the effect of Aloe vera addition on the viability and antifungal activity of TEP6 (Lactobacillus paracasei) bacteria immobilized on chitosan films for 28 days. Different chitosan and A. vera proportions and carbon sources at several pH values were tested as formulations for supporting the microorganism. Bacterial viability was maintained in freshly made films, with values of 10.4, 10.8 and 10.9 log CFU·g−1 for the formulations containing 70% (T11), 100% (T8) and 100% (T16) of A. vera, respectively. The same formulations (T8, T11 and T16) maintained bacterial viability for 14 days of film storage with a loss to values of 9.5 log CFU·g−1. By applying a quarter fraction 25–2 experimental design with an array of five factors, the factors with the greatest influence on viability and antifungal activity were determined. The optimal conditions for viability were the formulation with 100% A. vera, pH 4.5 and 0.1 M glucose. The antifungal activity of fresh films was influenced by the formulation with 10 g·L−1 glycerol and 100% A. vera, showing a 60% inhibition of fungal (Colletotrichum gloeosporioides) growth. The films developed in this study may have the potential to be used as coatings on vegetal products susceptible to attack by Colletotrichum gloesporioides.
