Soil Bacteria
Model of soil bacteria by pmecologic
A while back, I wrote about how many different kinds of bacteria there are on Earth. This proved to be a very popular topic, so in this week’s podcast, I describe recent work which explores a more direct but still not a simple question: How many different bacteria are there in a gram of soil? As the podcast describes, it’s not as easy to find out as you may think, but in summary, results suggest that in Alaskan soil there are 4,000 bacterial species per gram, and in soil from Minnesota, 10,000 per gram. Interestingly, only approximately 20% of the bacteria appear to be present in both soils, a perhaps unexpected degree of geographical variation. There’s a lot of bugs out there!

i want to know much on soil bacteria.its biochemical test and its result . type of bacteria present in the soil
Do you have a specific question?
[...] Biologists have long struggled with the problem of defining and recognizing species. Even animal and plant species are sometimes difficult to define, and philosophers disagree about the precise meaning of the word species. But microbes seem to pose special problems. Their small size and frequent uncultivability (only a very small percentage can grow in the lab, see previous posts on Soil Bacteria and How many bugs?) confound efforts to describe and archive type specimens. Worse still, prokaryotes reproduce asexually and so are unable to conform to Ernst Mayr’s Biological Species Concept, that is, groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups.

may i know that is most bacteria in soil are attached to soil particles?how can i prove this?
I do have the same question like Sue, What is the most bacteria soil population exits?
I have a practical question on how to eradicate a sour smelling bacteria in a large patch of soil about 10cm below the surface in my garden. It has a grey clay like appearance with white spots above the level.It dies when exposed to the sun for some time but is spreading very rapidly. I have bee told the only way to eradicate it is to remove all the bad soil and replace it which I tried to do but even small traces left behind seem to grow over time. I would really appreciate some advice on how to deal wioth this problem. Thank you.
[...] which covered virology basics. In August, while everyone else was on the beach, we discussed Soil Bacteria and RNAi and Cold Sores, among other topics. In September, we focused on quorum sensing, with [...]
I want to know what is the most effective bacteria that involve in carbon sequencer? Then, it is any effect of pesticide on beneficial soil microbe such as Nitrosomonas and Nitrobacter? I need some advices from of all of you here.
Is there a relatively easy method by which to obtain Clostridium acetobutylicum from soil?
Thank you.
what type of soil bacteria?
do all of you know about “screening antimicrobial activity and production of biofocculant for isolate soil sample”? if anyone know this please reply.
