Testing photoheterotrophic, autotrophic and fermentation of R.rubrum?

AI Thread Summary
To test the growth of R. rubrum bacteria under photoheterotrophic, autotrophic, and fermentation conditions, anaerobic environments are essential. For fermentation, the bacteria are incubated in the dark with fructose, while phototrophic conditions involve light exposure with fructose, and autotrophic conditions require light without any substrates. To achieve anaerobic conditions, one suggested method is using a GasPak jar, but the lack of such equipment at the school poses a challenge. An alternative approach discussed involves placing the bacteria in test tubes filled with sterile water and covering them with oil to create an anaerobic environment. For quantitative data, serial dilution and microspreading techniques were recommended, although specific methods for measuring growth rates were not detailed.

I need to test photoheteretrophic, autotrophic and fermentation growth of R.rubrum bacteria, all of which require anaerobic conditions. For fermentation, i am placing the bacteria with fructose in the dark, and for phototrophic in the light with fructose, and for autotrophic in the light with nothing. How should I do this to get some quantitative data??

How do I get anaerobic conditions,and how should i test this?, please help :confused:

Have you considered serial dilution and http://www2.hendrix.edu/biology/CellWeb/Techniques/microspread.html??

Thanks. Unfortunately our school has no equipment such as the GasPak you mentioned :frown:
However :smile:, the bacteria were put in test-tubes filled with sterile water, then covered with oil. Hopefully things will work out.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
