Cyanobacteria
Any embarrassing moments? Yes. In my first year as an assistant professor I was asked to give a talk in a neighboring department. They had just moved to a new building and I was the first speaker in their new auditorium. As I started my talk, we discovered that the auditorium was so new there weren't any light switches. I couldn't turn off the lights, and my slides were invisible. All those hou...
متن کاملStress response in cyanobacteria
Cyanobacteria are an important source of natural products. In this article, we briefly review the responses of cyanobacteria to different stresses. Abiotic stresses (temperature, salt, heavy metals, metalloid and ultraviolet (UV) influence cell growth and metabolism in cyanobacteria. Salt stress is a major abiotic factor that decrease...
متن کاملCircadian Rhythms in Cyanobacteria.
Life on earth is subject to daily and predictable fluctuations in light intensity, temperature, and humidity created by rotation of the earth. Circadian rhythms, generated by a circadian clock, control temporal programs of cellular physiology to facilitate adaptation to daily environmental changes. Circadian rhythms are nearly ubiquitous and are found in both prokaryotic and eukaryotic organism...
متن کاملUltraviolet radiation and cyanobacteria.
Cyanobacteria are the dominant photosynthetic prokaryotes from an ecological, economical, or evolutionary perspective, and depend on solar energy to conduct their normal life processes. However, the marked increase in solar ultraviolet radiation (UVR) caused by the continuous depletion of the stratospheric ozone shield has fueled serious concerns about the ecological consequences for all living...
متن کاملHydrogen production by Cyanobacteria
The limited fossil fuel prompts the prospecting of various unconventional energy sources to take over the traditional fossil fuel energy source. In this respect the use of hydrogen gas is an attractive alternate source. Attributed by its numerous advantages including those of environmentally clean, efficiency and renew ability, hydrogen gas is considered to be one of the most desired alternate....
