Abstract

Kapang Rhizopus sp merupakan salah satu mikroorganisme yang memiliki kemampuan tinggi untuk menghasilkan enzim selulase.Enzim selulase merupakan enzim yang dapat menghidrolisis selulosa. Hidrolisis meliputi proses pemecahan polisakarida di dalam biomassa lignoselulosa, yaitu: selulosa dan hemiselulosa menjadi monomer gula penyususnnya. Penelitian ini bertujuan untuk mengetahui produksi dan aktivitas enzim selulase terhadap aktivitas crude enzim selulase dari kapang Rhizopus sp dengan subsrtat ampas tebu (bagase). Metode penelitian menggunakan kuantitatif eksperimen dengan pola rancangan acak lengkap (RAL) dua faktorial. Perlakuan penelitian meliputi perbedan inokulum (K) yaitu 5% (K1), 15% (K2), 25% (K3) dan lama fermentasi (T) yaitu 3hari (T1), 6hari (T2), 9hari (T3), dan 12hari (T4). Data yang diambil dari perlakuan tersebut adalah kadar protein dengan metode brownstead lowry. Analisis data menggunakan variansi anava dua jalur dengan taraf signifikansi 5% setelah itu dilanjutkan dengan uji Beda Nyata Terkecil (BNT ). Hasil penelitian menunjukkan bahwa: Fhit > Ftab sehingga ada pengaruh antara konsentrasi inokulum dan lama fermentasi terhadap aktivitas crude enzim selulase dari kapang Rhizopus sp, Perlakuan perbedaan konsentrasi dan lama fermentasi mendapatkan kadar protein tertinggi 0,715 dengan konsentrasi 25%  dan lama fementasi 25%

Abstract

This study evaluated phytochemical composition, and in vitro and in silico antibacterial activity of Elaeocarpus ganitrus extract. Elaeocarpus ganitrus leaves, seed and fruit powder were extracted with absolute ethanol. Then, the extract was identified phytochemical compounds qualitatively and evaluated the antibacterial activity through in vitro against Staphylococcus aureus and E. coli. Molecular docking was conducted to evaluate the antibacterial mechanism of Elaeocarpus ganitrus extract. Elaeocarpus ganitrus leaves, seeds, and fruits extract presented positive tannin, saponin, cardiac glycoside, quinone, steroids, terpenoids, and anthocyanins. In vitro analysis performed Elaeocarpus ganitrus leaves strong inhibited Staphylococcus aureus growth and medium inhibition against E. coli. structure activity relationship revealed 14 of 72 compounds have high antibacterial activities. molecular docking of 7 compounds showed inhibition activity of D-alanin ligase of Staphylococcus aureus. Those compounds blocked the activity of D-alanine ligase at inhibitor sites of enzyme, and might be disrupted the cell wall synthesis. In conclusion, Elaeocarpus ganitrus contained several phytochemical compounds and has antibacterial activity both in vitro and in silico investigation.
