Research ArticleOpen accessEvery word in the titleApoptosis in Yeast is Modulated by Clove Leaf Extract and Eugenol Potentially by Interfering Caspase YCA1Septyani Amini, Rika Indri Astuti, Irmanida BatubaraApoptosis is a process of cell death important for preventing the development of diseases such as cancer, neurodegenerative disorders, autoimmune, and cardiovascular disease. Apoptosis is reported to be potentially induced by antioxidant compounds, including phytoextract. Thus in this study, we determined the potential of apoptotic modulation in yeast cells by clove extract, which was rich in eugenol. Apoptotic in yeast … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 15 Sep 2022 · 5,497 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleCell Longevity of Yeast Saccharomyces cerevisiae by Clove Bud Extract Treatment May Occur in Sirtuin-Independent PathwayZahrah Qolbaina Ariybah, Rika Indri Astuti, Sri ListiyowatiAccumulation of free radicals causes cell damage that leads to a phenomenon called aging. Antioxidant application is one potential strategy to avoid the damage of free radical accumulation. Many reports resume that clove, one of Indonesia’s spices, contain high amount of antioxidant. Our previous research had proven that clove extract could extend longevity in yeast Saccharomyces cerevisiae. However, cellular mechanism … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 3 Aug 2021 · 6,659 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleProduction, Extraction and Characterization of Lipases from the Antarctic Yeast Guehomyces pullulansLuis Lascano-Demera, Patricia Portero Barahona, Enrique Javier Carvajal BarrigaThe production of extracellular lipases from the Antarctic yeast Guehomyces pullulans is induced using an olive oil medium as an inductor substrate and a first characterization of its enzyme, using the protein extract obtained from the medium, is described. For this, the effect of pH and temperature on the lipase activity are evaluated and the enzyme kinetic for the lipase … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 11 Apr 2019 · 10,020 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleModulation 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).
