Research Nitrogen Fixation in Blue Green Algae

In summary, the conversation was about finding research on the rate of nitrogen fixation in blue green algae and a formula for calculating the amount of fixed nitrogen produced. The group suggested searching on PubMed/Medline and while no papers were found, it was noted that rates of nitrogen fixation vary depending on factors such as availability of certain elements and type of water. Specifically, the presence of the sulfate ion may inhibit fixation rates by different amounts in different types of water.

Does anyone know where I could find some research on the rate at which nitrogen fixation occurs in blue green algae?
Im looking for some sort of formula to calculate the amount of fixed nitrogen produced by a certain amount of blue green algae. Hopeing someone has seen something somewhere on this, I've had no luck finding anything.

i couldn't find anything there. its not a medical topic.

any other suggestions?

The problem would seem to be that rates of Nitrogen fixation very quite broadly. This site mentions some of the limiting factors. Among these are availability of Fe, Mo, sunlight, etc. The rates are higher in fresh water than in salt water, appearently because of the presence of the sulfate ion SO4=.

SO4= may inhibit fixation rates by 1-5% in fresh water, 15-20% in seawater, and 70% in highly saline waters.
 

1. What is nitrogen fixation in blue green algae?

Nitrogen fixation is the process by which blue green algae (also known as cyanobacteria) convert atmospheric nitrogen gas into a form that can be used by living organisms. This process is essential for the growth and development of plants and other organisms.

2. Why is research on nitrogen fixation in blue green algae important?

Research on nitrogen fixation in blue green algae is important because it can help us understand how this process occurs and how it can be optimized to benefit agriculture and the environment. This research can also lead to the development of more sustainable farming practices and reduce the need for synthetic fertilizers.

3. How do blue green algae fix nitrogen?

Blue green algae fix nitrogen through a process called diazotrophy, which involves the use of specialized enzymes to convert nitrogen gas into ammonia. The ammonia is then used to create essential nutrients for the algae and other organisms.

4. What are the potential applications of research on nitrogen fixation in blue green algae?

The potential applications of research on nitrogen fixation in blue green algae include improving crop yields, reducing the use of synthetic fertilizers, and promoting sustainable agriculture. This research can also have implications for bioremediation and biofuel production.

5. What challenges are associated with studying nitrogen fixation in blue green algae?

There are several challenges associated with studying nitrogen fixation in blue green algae, including the complex nature of the process, the difficulty in culturing and studying these microorganisms, and the potential for contamination from other microorganisms. Additionally, studying the impact of environmental factors on nitrogen fixation can also be challenging.
