Lignin decomposition of Oil Palm Frond by Pleurotus ostreatus with a variation of corn and rice-husk media

Abstract

This study aimed to decompose lignin from oil palm midrib (OPF) bonds using the fungus Pleurotus ostreatus with various substrates (corn and rice husk). Lignin and cellulose levels before and after mushroom culture were tested by the Chesson-Datta method. Substrate variation with corn and husk rice showed that the addition of corn did not play a role in lignin decomposition. After being given treatment, the best degradation was using 0.6 grams of rice bran and 0.4 grams of CaCO3, 22.01% for lignin and 32.74% for cellulose.

Risk Assessment of Petrol Filling Stations in a Metropolitical City of Kaduna State, Nigeria

“…One of the most basic and significant points in risk assessment is the classification of risks. The present-day risks can be grouped by the source, use, potential for harm and numerous other qualities [3,4,5]. The choice of group is normally a component of historical or professional decisions and relies upon the individuals or associations that are doing the grouping [6,7,8].…”

Effect of Alkaline 5% NaOH treatment with variations of immersion time on tensile strength and flexural strength of Betung bamboo internode

“…Due to these weaknesses and to optimize the application of Betung bamboo, chemical treatment is carried out in the form of alkaline treatment. According to Gozan et al [9], alkali treatment is the most widely used method, which aims to remove the lignin and oil content covering the fibre's outer surface. The effect that arises from the alkalization treatment is the change in hydrogen bonds in the fiber network structure, which causes the fiber surface to become rough.…”
