What an interesting riddle!
The bacteria discovered sounds a lot like blue-green algae (AKA cyanobacteria) which are a phylum of bacteria that are able to photosynthesize or use light energy to make their food, like the green leaves of plants. Cyanobacteria are critically important in making the atmosphere oxygen-rich due to their photosynthesis.The word cyano comes from the bacterias color: blue, although they tend to look green too because of their photosynthetic organelles. Blue-green algae can live as individual cells or in larger biofilms in aquatic and marine environments, damp soil or moistened desert rocks. They are even found in the fur of sloths, where they grow and camouflage the animal by making them look greenish like the forests they live in!
