Cellulose and Pectic Polysaccharides01:15

Cellulose and Pectic Polysaccharides

3.4K
 Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth.  Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the...

Role of Microtubules in Cell Wall Deposition01:02

Role of Microtubules in Cell Wall Deposition

2.3K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...

Area of Science:

  • Chemical Engineering
  • Biotechnology
  • Sustainable Chemistry

Background:

  • Cellulose conversion to 5-Hydroxymethylfurfural (HMF) offers sustainable alternatives to petroleum-based products.
  • Efficient HMF production is hindered by complex interactions of operational variables.

Purpose of the Study:

  • Develop a machine learning (ML) model to optimize HMF production from cellulose.
  • Identify key factors influencing HMF yield through feature importance analysis.
  • Employ Bayesian optimization for maximizing HMF yield.

Main Methods:

  • Compiled a comprehensive dataset from existing literature for statistical analysis.
  • Evaluated eight ML models, with CatBoost Regressor showing superior performance.
  • Conducted feature importance analysis and Bayesian optimization for multi-objective optimization.

Main Results:

  • CatBoost Regressor achieved R² of 0.76, RMSE of 4.72, and MAE of 5.2.
  • Operational conditions (time, temperature) were most significant (41.0%), followed by catalyst (33.0%) and solvent (26.0%) properties.
  • ML-based optimization yielded 48.1% HMF, with experimental validation showing high accuracy.

Conclusions:

  • Machine learning effectively addresses challenges in cellulose-to-HMF conversion.
  • Identified operational parameters as crucial for optimizing HMF production.
  • This research provides insights for advancing sustainable bio-based chemical manufacturing.
