The future may provide a microplastics solution in the form of specific bacterial combinations where, in the same way as we combine cytotoxic drugs to fight specific forms of cancer, plastic-digesting combinations can be used to degrade different types of polyethylene. Picture Source: eurekabrewing.files.wordpress.com. Optimal growth of B. licheniformis occurs around 50C, but the organism can survive at much higher/lower temperatures for extended periods because it is spore-forming. Cross-links between peptide chains create a crystal-lattice like structure [6].
