The bacteria P. aeruginosa is a fluorescent, or light-producing bacteria, that has many features which distinguish it from other kinds of bacteria. It is also able to withstand many disinfectants The blue light acne treatment light also does not cause tanning or skin burn. Studies have also found that using blue light therapy for 3 consecutive days has been shown to reduce bacteria in the pores by up to 99.9% with up to 80% of patients showing an overall improvement over 3 months, although 10% of patients did not find any improvement at This arrangement enables strong absorption of blue light and effective conversion of its inherent photon energy into molecules that enhance bacterial kill. Indeed, endogenous bacterial porphyrins, a byproduct in heme biosynthesis, has been exploited in phototherapy to treat bacterial infections, such as acne [12 ]. Moreover, the rate at which a bacteriostatic antibiotic kills one species of bacteria, for example, Escherichia coli, can be markedly less than the rate at which it kills another species, for There are three classes of UV light: UV-A, UV-B and UV-C. UV-A and UV-B light cause sunburns and premature skin aging, and exposure to both is associated with the development of skin cancer. UV-C January 29, 2013. Blue light has been used to kill potentially-lethal Pseudomonas aeruginosa bacteria (pictured) in the skin and soft tissues of lab mice. View 1 Images. Over the past few years Blue light-emitting diodes (LEDs) show promise as a chemical-free way to preserve food, according to new research. The LEDs work best in cold temperatures of 4°C and 15°C (about 39-57°F) and If all the measurements line up, UVC light can kill 99.9% of viruses and bacteria. One limit to UVC light is that it disinfects only what it sees. Sometimes, the light source needs to be a3qY.
