1.1 Bioenergy from Biomass
Bioenergy, derived from biomass sources such as plants, algae, and agricultural waste, is a promising area of renewable energy. Biotechnology enhances bioenergy production through advanced conversion processes like hydrothermal liquefaction, pyrolysis, and fermentation. These processes convert biomass into high-quality biofuels that can be directly blended with gasoline or diesel.
1.2 Algal Bio-Oil
Phycobloom, a British startup, uses synthetic biology to produce bio-oil from algae. This method is fast, inexpensive, and sustainable, as it reuses the same batch of algae and requires only air, water, and sunlight. This innovation reduces the transportation sector’s dependency on fossil fuels and closes the loop between greenhouse gas emissions and fuel production.
2. Advanced Bioremediation and Waste Treatment
Biotechnology is also crucial in the biological treatment of waste and wastewater, which can contribute to energy efficiency and sustainability. By using microorganisms to break down pollutants, biotechnology helps in maintaining environmental health and reducing the environmental footprint of human activities.
3. Protein-Based Innovations
3.1 Proton-Conducting Proteins
Researchers at the University of California, Irvine, have developed biocompatible proton-conducting materials from naturally occurring proteins found in cephalopods. These proteins can be genetically engineered to tune their electrical properties, making them versatile for integration into protonic flow systems essential for renewable energy technologies like fuel cells and biosensors.
3.2 Disulphide Bonded Proteins
A new tool developed by researchers at Oulu University enables the production of disulphide bonded proteins in bacteria. This innovation eliminates the need for complex refolding processes, significantly increasing protein yields and providing a cost-effective solution for drug development, enzyme production, and diagnostics.
4. Gene Expression Control in Agricultural Biotechnology
4.1 Synthetic Transcription Regulators
A research team at Lawrence Berkeley National Laboratory has created a novel synthetic production strategy for transcription regulators using elements from yeast and plant species. This technology allows for targeted, environmentally responsive, and tissue-specific gene expression, which is crucial for developing new and improved plant species for food production.
5. Integration with Renewable Energy Technologies
5.1 Biofuel Cells
French startup BeFC has developed a paper-based biofuel cell system that uses enzymes to convert glucose and oxygen into electricity. This sustainable and non-toxic technology is suitable for low-power applications and represents a novel integration of biotechnology with renewable energy solutions.
