Abstract

Introduction: This study was carried out to investigate thaumatin profile in Thaumatococcus daniellii fruit cultivated in different growth condition. Methods: Three different samples that used were T. daniellii that grown naturally, T. daniellii treated with low fertilizer and T. daniellii treated with high fertilizer. The aril part of the fruit contain intense sweetener protein that can substitute sugar and other artificial sweetener was analaysed by Bradford assay and SDS-PAGE for determination of protein content and differences in protein expression repectively. Results: The total protein concentration of each sample calculated using Bradford assay were 0.367 ± 0.007 µg/µl, 0.343 ± 0.014 µg/µl and 0.426 ± 0.027 µg/µl for T. danielli grown at natural condition (uncontrolled environment), T. daniellii treated with low fertilizer and T. daniellii treated with high fertilizer respectively. All T. daniellii samples showed the presence of thaumatin as shown by the SDS-PAGE image. Only a single band appeared on the SDS-PAGE at the molecular weight of 22 kDa which is the actual size for thaumatin. The band intensity of T. danielli treated with high fertilizer appeared to be highest compared to the other two samples showing high in protein expression. Conclusion: This finding will be useful for other researchers to find out more about this plant for thaumatin production with the best growth condition.
