Enzyme Engineering

Enzyme engineering services leverage the power of natural catalysts - enzymes - to break down complex waste materials into simpler, usable compounds. This process, known as enzymatic hydrolysis, involves carefully selecting and engineering enzymes with specific properties to target the desired waste components. By optimizing enzyme activity, stability, and substrate specificity, we achieve efficient and sustainable waste valorization.

• Bioprospecting: Identifying naturally occurring enzymes from microorganisms that thrive in diverse environments.
• Genetic engineering: Modifying the genetic code of enzymes to alter their properties, such as activity, stability, and substrate specificity.
• Directed evolution: Using iterative rounds of mutation and selection to create enzyme variants with improved characteristics.
• Protein engineering: Rational design of enzymes based on their 3D structure and function.

• Waste management: Converting municipal solid waste, food waste, agricultural residues, and industrial byproducts into valuable products, reducing landfill burden and promoting resource recovery.
• Biofuel production: Producing biodiesel, bioethanol, and other biofuels from renewable waste streams, contributing to sustainable energy solutions.
• Animal feed production: Generating protein-rich feed supplements from food waste and other organic waste streams, enhancing the sustainability of animal agriculture.
• Fertilizer production: Recovering nutrients from organic waste streams to produce biofertilizers, promoting sustainable agriculture and reducing reliance on synthetic fertilizers.
• Biogas production: Enhancing biogas production from anaerobic digestion of organic waste by pre-treating the waste with enzymes to improve digestibility and biogas yield.

• Enzyme Discovery and Expression: Enzyme identification and expression from microbial strains are achieved through genome sequencing, transcriptional analysis, and bioinformatics-guided approaches.
• Assay Design and Activity Assessment: New assays are designed to assess enzyme activity and identify the enzyme sequence encoding the target activity following expression in strains such as Escherichia coli or Pichia pastoris.
• Enzyme Engineering and Optimization: Catalytic capabilities are improved by altering enzyme amino acid sequences via rationally guided changes or directed evolution.
• Domain Engineering and Hybrid Enzymes: Complex modular enzymes are engineered to alter synthetase products, and hybrid enzymes are created by merging domains with distinct functions, such as glycosyltransferase recognition domains.
• Cellular Production and Scale-Up: The engineered microbial strain is used for direct large-scale product formation or for enzyme isolation to enable cell-free biocatalytic processes.
