In the process of grape wine fermentation, it has been long known that different flavor, aroma and taste characteristics are usually from various microbes associated grape strains and grape varieties. In the study, we were interested in understanding diversity of microbial niches of fermented glutinous rice ball developed in variety of fruit wine fermentation. Since different raw materials, fruits together with different microbial consortium associated with fruit surface itself affected various dominant culturable bacterial and fungal species. In the study, freshly prepared juices of fruits; mangoes and apples after processing without the pasteurization at 65°C for 30 min revealed dissimilar pH profiles and reducing sugar contents as well as alcohol production. Under microbiological examination as well as serial dilution agar plate technique, diverse dominant bacterial and fungal isolates were detected in the wine sample of the fruits pasteurized. The nutrients originated in apple sample caused more populations of microbes, including dominant bacilli, detected in the fermented broth since they were found in apples than in mangoes (104-1013 and 104-106 cells/ mL, respectively). From the results, it was shown that different nutrient sources played more important roles in stimulation of variations in microbial assort and possibly more complex in fermented juice qualification. The understanding in microflora consortium involving in wine fermentation for each fruit type should be helpful in monitoring and reflecting the concurrent microbial activity present in the large scale of wine production, reducing the risks of existing spoilage species.
