Application of Cassava Peel and Waste as Raw Materials for Xylooligosaccharide Production using Endoxylanase from Bacillus subtilis of Soil Termite Abdomen
RATNADEWI, Anak Agung Istri; SANTOSO, Agung Budi; SULISTYANINGSIH, Erma; HANDAYANI, Wuryanti (Procedia Chemistry, 2017-01-30)Xylooligosaccharides (XOS) are the sugars produced from xylan hydrolysis. XOS have a prebiotic characteristic by promoting the growth of probiotic microorganisms. Xylan containing agriculture wastes e.g. rice straw, ... -
Determination Kinetic Parameters of Endo-β-1,4-D-Xylanase from Abdomenal Termites with Xylan Oat and Birchwood
RATNADEWI, Anak Agung Istri; HIMMAH, Linda Faiqotul; MULYONO, Tri; HANDAYANI, Wuryanti; KRISHNABUDI, NG.; SUDARKO, Sudarko (Indonesian Chimica Letters, 2022-06)Parameters kinetic (KM, VMax, and kCat) endo-β-1,4- D-xylanase under optimum conditions with oat spelt xylan and birchwood substrate have been investigated in this study. Hydrolysis of endo-β-1,4-D-xylanase using variation ... -

Therefore, this area grows to be a leading producer of rose flowers in Jember district. However, ... -
Isolation and Characterization of Uricase Produced from Chicken Liver
HANDAYANI, Wuryanti; NAJA, Nasrul Amaliyatun; JOENATA, Muhamad Kiki Afindia; RATNADEWI, Anak Agung Istri (Journal of Bio-Molecule Research and Engineering, 2022-05-12)Uricase is an enzyme that degrades uric acid into allantoin. One of the uricase sources is obtained from chicken species (Gallus gallus domesticus) liver which are broiler and native chicken. This study aims to determine ... -
Lactobacillus Casei Fermentation Towards Xylooligosaccharide (Xos) Obtained from Coffee Peel Enzymatic Hydrolysate
RATNADEWI, Anak Agung Istri; ZAIN, Mamluah Husnul Amaliyah; KUSUMA, A. A. Ngurah Nara; HANDAYANI, Wuryanti; NUGRAHA, Ari Satia; SISWOYO, Tri Agus (Biocatalysis and Agricultural Biotechnology, 2019-11-29)fee peel waste contains fibers including xylan, a polymer that constitutes hemicelluloses. Xylan can be extracted from coffee peel and used for xylooligosaccharide (XOS) production. XOS is an oligomer that has the potentials ... -

Optimization of Centrifugation Speed and pH in Extraction of Uricase Enzyme from Goat Liver
HANDAYANI, Wuryanti; UTARTI, Esti; KRISMIADI, Riki Juni; RATNADEWI, AA. Istri (INDONESIAN CHIMICA LETTERS, 2022-12-21)The human body does not have an enzyme that can break down uric acid, so the accumulation of uric acid can cause disease. This problem can be overcome by uricolytic therapy by utilizing the activity of the uricase ... -
Prebiotic Potential of Xylooligosaccharides Derived from Cassava Dregs in Balb/c Mice Colon
HAFIDAH, Ani Harfilia; SULISTYANINGSIH, Erma; HANDAYANI, Wuryanti; RATNADEWI, Anak Agung Istri (TROPICAL AGRICULTURAL SCIENCE, 2018-08-29)Xylooligosaccharides (XOS) are polymers of the sugar xylose bound by β(1→4) glycoside bonds. XOS have potency as a prebiotic and can be produced from agricultural waste such as cassava dregs. The purpose of this study ...
