Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.

Yellow- Green Wavelength of light at peak absorption of 565nm.
Halobacterium is known to be a member of Archaea
and they thrive in very salty environment such as Great Salt lake and Dead Sea. Halobacteria under the process of photosynthesis
with chlorophyll and they make their ATP from the sunlight using bacteriorhodopsin
and halorhodopsin as photosynthetic pigments.
However, photosensory pigements found in
Halabacterium were:
1. photosystem 565 which is used to respond to yellow
–green light in other for cell to find optimum conditions for ATP synthesis and
photophosphorylation and they have peak absorbtion at 565nm.
2. Photosystem 370 nm appears to be responsible
for the protective avoidance of blue/UV light.
