Synthetic biology is being used to develop sugar substitutes and zero-calorie alternatives. Many agri products like Indigo are being replaced by advances in synthetic biology. Soil microbes are being studied for their genomes and are being sequenced economically. It is possible by low-cost DNA sequencing technology. Some natural molecules can be replicated. Pichia Pastoris produces haeme molecules to resemble the taste and aroma of animal blood. It could lead to vegan hamburgers. In evolution, certain paths take millions of years. Biologists now could accelerate this process to find alternatives. Petrochemistry is not suitable to environment. Synthetic biology could give us new alternatives without affecting the environment. It could lead to the concept of Industry 5.0. There could be a Synbio-as-a-service.
