This document discusses several potential applications of bacteria: 1) A bacteria calculator that could solve the Hamiltonian problem was created in 2009 using modified E. coli bacteria. 2) Bacteria that completes the cocoa drying and fermenting process, using acids like yeast, lactic, and acetic acid to reduce microbes in cocoa production. 3) Researchers created bacteria that produces spider silk proteins using genes from spiders inserted into E. coli, aiming to replicate the properties of silk from silkworms. 4) Developing bacteria could help prevent allergies like peanuts by addressing the underlying causes of allergies. 5) Bacteria is being used as a timer by employing biological
