some bacteria are helpful in presence of light.
Answers
Answer:
Bacteria sensitive to light
Explanation:
A team of researchers, including Stanford scientists, has discovered that certain single-celled infectious bacteria can tell the difference between light and dark, and actually increase their infectiousness 10-fold when hit by sunlight.
Answer:
In the presence of light, Brucella, the bacteria that cause the infectious disease brucellosis, and more than 100 other kinds of bacteria contain proteins originally thought to be functional only in plants, according to Winslow Briggs, one of the researchers and director emeritus of the Carnegie Institution Department of Plant Biology. "Many of these bacteria have been pretty well studied, but nobody has ever showed light responses in them," said Trevor Swartz, the study's lead author and a former postdoctoral fellow in Briggs' lab. "In Brucella, we showed that light actually is controlling infection."
