Contact SupplierAcid Cellulase – Uses in Sugar, Ethanol & Distillery Industries\\\
Acid cellulase is an enzyme complex that hydrolyzes cellulose into glucose under acidic pH conditions. It is a vital tool in industries processing plant biomass, especially where cellulosic material (bagasse, grain husks, molasses residues) needs to be broken down into fermentable sugars.
\\\\\\š 1. What is Acid Cellulase?\\\Enzyme class: Hydrolase (EC 3.2.1.4)
\\\Primary activity: Breaks β-1,4-glycosidic bonds in cellulose
\\\Optimal pH: 4.0 – 5.5
\\\End products: Glucose, cellobiose
\\\Derived from: Fungi like Trichoderma reesei, Aspergillus niger
\\\Lignocellulosic ethanol: Converts agro-waste (bagasse, corn stover, rice husk) into fermentable sugars
\\\In saccharification step of SSF (Simultaneous Saccharification and Fermentation)
\\\Increases overall ethanol yield
\\\Reduces viscosity and improves substrate flow
\\\Treats bagasse, filter cake, and trash to release entrapped sugars
\\\Enhances sugar recovery from molasses and fibrous residues
\\\Helps in clarification and reduction of non-sugar solids
\\\Applied to grain or molasses-based mash
\\\Breaks down residual cellulose in grain husks or pressmud
\\\Increases fermentable carbohydrate availability
\\\Improves fermentation efficiency and alcohol recovery
\\\| Breaks down cellulose | \\\Releases glucose from fibrous biomass | \\\
| Improves fermentation | \\\More sugars for yeast = higher ethanol yield | \\\
| Reduces waste load | \\\Converts waste to valuable inputs | \\\
| Works in acidic conditions | \\\Compatible with typical fermentation pH (4.5–5) | \\\
| Reduces viscosity | \\\Easier handling of thick biomass slurries | \\\
\\\
Typical dosage: 0.1 – 0.5% w/w of dry substrate
\\\pH range: 4.0 – 5.5 (optimum)
\\\Temperature: 45°C – 60°C
\\\Retention time: 2–6 hours (varies by substrate & enzyme strength)
