Temperature effects on bacterial movement.

Temperature effects on bacterial movement.

Details are presented for the construction of a simple precision temperature-controlled chamber for investigating bacterial motile behavior. Independent of original incubation temperature, all species of motile bacteria observed showed a five- to sevenfold increase in average translational velocity (micrometers per second) as the environment temperature was incremented over the range from 10 to...

Temperature Effects on Bacterial Phytochrome

Bacteriophytochromes (BphPs) are light-sensing regulatory proteins encoded in photosynthetic and non-photosynthetic bacteria. This protein class incorporate bilin as their chromophore, with majority of them bearing a light- regulated His kinase or His kinase related module in the C-terminal. We studied the His kinase actives in the temperature range of 5°C to 40°C on two BphPs, Agp1 from Agroba...

Temperature Tincture: The Effects of Temperature on Bacterial Pigmentation

Objectives/Goals I really enjoyed my project this year. In my project, I tested how temperature affected the pigmentation of four different bacteria. From my research, I knew that the bacterium Serratia marcescens alters its color at different temperatures, and I wanted to explore this. I also wanted to see if this applied to other pigmented bacteria. Methods/Materials My project consisted of q...
