The World Health Organization (WHO) estimates that one third of the global population is infected with Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB), which is responsible for millions of death each year. Current therapy of TB consists of multiple expensive antibiotics and lengthy treatment, up to six months for drug-sensitive TB strains, and nine months to one year ...

Oxygen concentrations in the atmosphere and surface oceans...
