Ibrahim Ibn Mollah Mosharraf Dear sirWith respect to your queries please find herewith the reply for each one of them

• You can not culture any bacteria at home at home as it needs specific media and aseptic environment to produce.
• Nitrifying bacteria can be used for increasing the rates of nitrification but before going in to that they are providing which bacterial culture as nitrification is two step process and you need two different types of bacteria to accomplish the whole nitrification process
• Azotobacter can not breakdown ammonia to create nitrogen. Its role is to fix atmospheric nitrogen i.e. N2 in the form of ammonia with the help of nitrogenase enzyme its fu
• You can not culture any microorganisms at home. 

For making biofertilizers you need to have pure culture of microorganisms, it should be non-toxic, non-pathogenic. It should possess efficiency characteristics which needs to betested in laboratory. Moreover, production of these microorganisms requires specific media and specific environmental conditions to grow.

K solubilization is done by a wide range of saprophytic bacteria, fungal strains and actinomycetes . There are strong evidences that soil bacteria are capable of transforming soil K to the forms available to plant effectively. There is considerable population of KSB in soil and in plant rhizosphere. These include both aerobic and anaerobic isolates that the most frequently KSB in soil are aerobic. These include both aerobic and anaerobic isolates that the most frequently KSB in soil are aerobic. A considerably higher concentration of KSB is commonly found in the rhizosphere in comparison with non-rhizosphere soil .

The most important is to see their complentarity when cultured as mix culture , otherwise whole exercise is a futile one. We need to establish in - vitro whether these species are antagonistic or synergistic to each other when co - cultured...
