Production, Characterization and Application of Biosurfactant for Cleaning Cotton Fabric and Removing Oil from Contaminated Sand

Processes, Journal Year: 2024, Volume and Issue: 12(11), P. 2584 - 2584

Published: Nov. 18, 2024

Biosurfactants are a group of environmentally friendly amphiphilic molecules that applicable in numerous industries as essential biotechnology products, such food production, cleaning pharmacology, cosmetics, pesticides, textiles and oil gas fields. In this sense, knowing the potential these biomolecules, aim work was to produce biosurfactant, characterize it regarding its chemical surfactant properties investigate removal contaminants cotton fabrics. The biosurfactant initially obtained from cultivation microorganism Candida glabrata UCP 1002 medium containing distilled water with 2.5% residual frying oil, molasses corn steep liquor agitated at 200 rpm for 144 h. reduced surface tension 72 29 mN/m. toxicity evaluated using Tenebrio molitor larvae demonstrated non-toxicity. applied degreaser engine on fabric, showed 83% (2× CMC), 74% (1× CMC) 78% (1/2× removal. Therefore, produced has promising emulsifying application various industrial segments.

Characterization of Cellulosic Pulps Isolated from Two Widespread Agricultural Wastes: Cotton and Sunflower Stalks

Polymers, Journal Year: 2024, Volume and Issue: 16(11), P. 1594 - 1594

Published: June 4, 2024

Globally, huge amounts of cotton and sunflower stalks are generated annually. These wastes being underutilized since they mostly burned in the fields. So, this work, we proposed a three-step method consisting acid pre-treatment, alkaline hydrolysis, bleaching for extraction cellulose pulps. pulps were characterized to assess their morpho-structural thermal properties. The design experiments response surface methodology used optimization pre-treatment order achieve maximum removal non-cellulosic compounds obtain enriched cellulose. For stalks, optimal conditions identified as reaction time 190 min, temperature 96.2 °C, an (nitric acid) concentration 6.3%. optimized time, temperature, 130 73.8 8.7%, respectively. obtained after contained more than 90% However, special care must be taken during process, especially it causes solubilization great amount material. characterization revealed that process led with around 69–70% crystallinity stability range 340–350 ready conversion into derivatives industrial applications.
