Abstract

Xylanase is a type of enzyme that hydrolyzed of β-1,4 glycosidic bonds in xylan, breaking it down into its constituent monomers. Xylanolytic enzymes are pivotal in processes such as bio-bleaching of pulp, textile manufacturing, and the recycling of waste paper. Successful bioconversion of xylan or lignocellulose relies on the collaborative action of various xylanolytic enzymes, including endo-xylanase, β-xylosidase, and other accessory enzymes. Docking simulations using Auto Dock 4.2 were conducted to analyze the interaction between ligands and xylanase, utilizing PDB 1B3V and 1FCE. Ligand interaction with xylanase was further investigated through molecular dynamics. The xylanase from Penicillium simplicissimum (PDB 1B3V) exhibited comparable affinities for α-D-xylopyranose and β-D-xylopyranose. In contrast, the xylanase from Clostridium cellulolyticum (PDB 1FCE) demonstrated a stronger affinity for β-D-glucopyranose than for 4-thiouridine. Molecular dynamic investigations indicated the stability of both structures against the tested ligands. These findings provide a foundation for potential experimental validations and the application of molecular mechanics techniques. Such approaches could unveil the detailed catalytic mechanism and bolster the industrial efficacy of the enzyme.

Abstract

Kegiatan ini merupakan bagian salah satu cara sosialisasi hidup sehat era endemi atau pasca covid-19. Ulasan ringkasanya dapat disampaikan berikut ini; Pada akhir abad ke-18, Edward Jenner, seorang dokter Inggris, membuat terobosan penting dalam perkembangan vaksinasi. Jenner mengembangkan vaksin cacar pertama yang berhasil pada tahun 1796. Observasi pada para pemerah susu yang tertular/terpapar cacar sapi, yang menunjukan gejala tidak terlalu parah, dan gejala itu akibat dari terlindungi cacar sapi. Bintil-bintil cacar sapi disuntikan ulang pada seorang anak laki-laki, yang menunjukkan kekebalan terhadap cacar. Hal ini menjadi dasar bagi vaksinasi modern. Selanjutnya, Pada akhir abad ke-19, Louis Pasteur mengembangkan vaksin rabies, yang menandai tonggak sejarah lain dalam sejarah vaksin. Hasil karyanya menunjukkan bahwa vaksin dapat mencegah penyakit yang disebabkan oleh infeksi virus dan/atau bakteri. Keberhasilan vaksinasi cacar menyebabkan kampanye vaksinasi yang meluas untuk membasmi cacar. Para ilmuwan terus meneliti dan mengembangkan vaksin baru untuk memerangi penyakit menular yang baru muncul dan memperbaiki vaksin yang sudah ada. Contoh penting termasuk pengembangan vaksin untuk melawan human papillomavirus (HPV), retrovirus, dan covid-19. Metode structural equation modelling (SEM) digunakan untuk mengetahui respon publik terkait tulisan ini. Evalusi uji pretest dan post test terhadap 32 responden berumur kisaran 19 tahun dan 12 responden berumur kisaran 18 tahun, berturut-turut sebagai berikut; sangat mengerti (4,32), mengerti (73,45), kurang mengerti (20,85) dan tidak mengerti (1,55); dan sangat mengerti (1,38), mengerti (75), kurang mengerti (22,22) dan tidak mengerti (1,4). Secara umum, responden yang merumur 19 tahun lebih mengerti daripada responden yng berumur 18 tahun, walaupun perbedaannya tidak terlalu berarti.Kata kunci: vaksin, cacar, rabies

Abstract

The selective aqueous phase hydrogenolysis of furfuryl alcohol (FFalc) to 1,5-pentanediol (1,5-PeD) using supported bimetallic ruthenium-tin (Ru-Sn) catalysts on various metal oxide supports (e.g., TiO2, ZnO, ZrO2, Nb2O5, g-Al2O3) and its combination were investigated systematically. The catalysts were prepared via coprecipitation-hydrothermal at 150 oC for 24 h, followed by reduction with H2 at 400 oC for 2 h. Supported Ru-Sn on TiO2(A), g-Al2O3, and ZrO2 catalysts exhibited higher yield of 1,5-PeD (55-69%) than that other catalysts at 180 oC, H2 10-30 bar for 3-5 h. However, those supported catalysts showed poor recyclability after the first reaction run, and therefore further examination on g-Al2O3 supported Ru-Sn was performed. The Ru-Sn catalyst supported on g-Al2O3-metal oxide composites (metal oxides: ZrO2, TiO2(A), TiO2(R), ZnO, Nb2O5, and C) afforded higher FFalc conversion and yield of 1,5-PeD than that of unmodified g-Al2O3 at 180 oC, H2 30 bar for 3 h. Among them, the Ru-Sn/g-Al2O3-TiO2(A) (33%) catalyst could afford the highest yield of 1,5-PeD (80%) at 99% conversion FFalc at 180 oC, H2 10 bar for 5 h. Around 95% of this catalyst can be recycled after the second reaction run and the activity can be restored to initial after reactivation with H2 at 400 oC for 2 h with a 69% yield of 1,5-PeD at 97% FFalc conversion.
