Experimental investigation on seaweed (sargassum wightii) derived using methanolic extracts

Abstract

Seaweeds are a primitive type of plant and macro algae, which usually grow in the regions of backwaters, estuaries, and seas, especially in shallow water. They are typically formed, attached, and visualized to the coral reef, rocks, and other substrata wherever available. The seaweeds are collected from the Kanyakumari region and processed for methanol production. The methanol is extracted from the processed seaweed using the Saccharification method. The physicochemical properties of methanol are determined as per ASTM standards. The yield (%) of methanol production depends on the concentration of the substrate and the time duration (24, 48, and 72 h). It is observed that for a substrate concentration of 15%, a maximum yield of methanol is observed. In contrast, when the substrate concentrations lie below 10%, there is a decrease in the methanol yield for all the time durations investigated. Therefore, the maximum yield (51.2%) of methanol is obtained for a substrate concentration of 15% with a time period of about 48 h.The present work concentrated on producing methanol from a high concentration and choice of seaweed (Sargassum wightii).
