Pigment analysis and ammonia excretion in herbicide tolerant cyanobacteria.
Isolation of cyanobacteria was attempted from herbicide applied rice soils. The predominant genera were Westiellopsis followed by Anabaena, Nostoc and Oscillatoria. The herbicide tolerance was further tested by growing the cyanobacterial cultures in BG-11 medium supplemented with varying concentrations of the commonly used rice herbicide, viz butachlor under in vitro condition. The chlorophyll-...
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 کاملNitrogen and ammonia assimilation in the cyanobacteria: purification of glutamine synthetase from Anabaena sp. strain CA.
Glutamine synthetase was purified from the cyanobacterium Anabaena sp. strain CA, a newly isolated marine organism. This organism grows rapidly under nitrogen-fixing conditions and therefore is ideally suited for studies concerning cyanobacterial nitrogen metabolism. Studies were conducted to optimize the production of glutamine synthetase by Anabaena CA. The highest specific activities were ob...
متن کاملCyanobacteria
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 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...
