Research ArticleOpen accessIn the author namesModulation of Aging in Yeast Saccharomyces cerevisiae by Roselle Petal Extract (Hibiscus sabdariffa L.)Sarima, Rika Indri Astuti, Anja MeryandiniCellular aging drives diseases. Free radicals are called the main cause of cellular aging. Antioxidants can protect the body from free radical attack by reducing its negative effects. An antioxidant source can be obtained from plants, such as roselle (Hibiscus sabdariffa. L). This research was conducted to analyze the ability of roselle petals extract to increase the life span of … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 1 · 6 Apr 2019 · 9,646 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEthanol Production by Novel Proline Accumulating Pichia kudriavzevii Mutants Strains Tolerant to High Temperature and Ethanol StressesRika Indri Astuti, Sena Alifianti, Ratu Nabila Maisyitoh et al.Accumulation of osmoprotectant molecule, proline, has been reported to induce a stress tolerance phenotype in yeast cells. In this study, two ethanologenic isolates of yeast, Pichia kudriavzevii (R and T), both capable of using both five and six sugar compounds to produce ethanol, were mutated via ethyl methanesulfonate (EMS) treatment. Prolineaccumulating mutant strains were selected by using proline-analogue (L-azetidine-2-carboxylic acid). … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 11 Sep 2018 · 7,838 accessesView PDF Cite
