1.denitrifying bacteria
2.sulphur bacteria
3.ammonifying bacteria
conditions in the sense
1.temperature
2.pH
3.INCUBATION TIME
ALL FOR THE BACTERIAS GROWTH......IM DOING A PROJECT IN SOIL MICROBIOLOGY... SO IT LL BE USEFUL FOR ME...
THANK YOU..

This website addresses the first two conditions for optimal growth for soil bacteria:

The "optimum growth temperature ranges between 25Â°C and 40Â°C."
The optimum pH for "most bacteria" is between "pH 6.5 and 7.5."

The website below has lots on denitrying bacteria - you might find Appendix G ("Growing denitryfying bacteria from soil") particularly useful.
