Cellulose and Pectic Polysaccharides01:15

Cellulose and Pectic Polysaccharides

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 parenchyma cells of...
Role of Microtubules in Cell Wall Deposition01:02

Role of Microtubules in Cell Wall Deposition

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 disassembly and...

Overview of Cell-Matrix Interactions

The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

Cell-matrix's Response to Mechanical Forces

In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue. 
Anchoring junctions mechanically attach a cell to the...
The Extracellular Matrix01:29

The Extracellular Matrix

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Area of Science:

  • Biomass utilization and sustainable resource management.
  • Biobased economy and renewable resources.
  • Cellulose and lignocellulosic materials science.

Background:

  • The transition to a biobased economy increases demand for renewable resources like cellulose.
  • Competition for lignocellulosic materials is rising across traditional and emerging industries (e.g., paper, biofuels, green chemicals).
  • Variable availability and quality of lignocellulosic feedstocks necessitate careful selection for specific applications.

Purpose of the Study:

  • To develop a practical 'cellulose resource matrix' for informed decision-making by stakeholders.
  • To categorize available and emerging lignocellulosic resources based on quality, quantity, processability, and performance.
  • To bridge the gap between complex scientific data and accessible information for entrepreneurs and industry professionals.

Main Methods:

  • Inventory of current and novel cellulose-containing raw materials, including exotic sources.
  • Identification and recording of key chemical, physical, and market properties (price, availability).
  • Review of cellulose extraction/refining processes, feedstock demands, and processing parameters.
  • Survey of current and emerging markets and their specific requirements for cellulose raw materials and processes.
  • Data reduction via clustering of raw material, process, and market characteristics.
  • Development of a database structure for stakeholder queries.

Main Results:

  • A detailed matrix structure was composed, identifying key elements and their interrelationships.
  • Clusters of the most relevant and characteristic properties for raw materials, processes, and markets were defined.
  • The matrix aims to provide indicative answers for stakeholder choices regarding feedstock, process, or market.

Conclusions:

  • The developed cellulose resource matrix serves as a practical tool for navigating the complexities of the biobased economy.
  • Effective categorization and data management are crucial for optimizing the use of lignocellulosic resources.
  • Further research is needed to fill information gaps and refine the matrix for comprehensive decision support.
