Soil bacteria (Besides molecular tools, suggest the biochemical characterization kit for unknown bacterial isolates of the rhizosphere soils of mangroves)
For soil bacteria prepared kits often fail as most kits are directed for the identification of bacteria in fields with a large market (medical, veterinary, food safety). If you want to identify a large number of bacteria the preparation of individual vials for the testing of single biochemic properties can be helpfull and bacteria can by identified using published lists (e. g. Bergey's Manual).
A wide range of bacteria can also be identified by MALDI-TOF analysis for almost no cost of consumables. However, the respective instrument and database is required. Alternatively, using 16S sequencing could be suitable for identification of soil bacteria.
Mobio do a 'Soil Power Kit' for gDNA extraction I think. Alternatively, Qiagen have a number of kits that work very well.
The Soil Power kit is suitable for total DNA extraction of complex bacterial populations like in soil or stool samples. Using this DNA metagenomics can be performed using next generation sequencing. If understand the question correctly a single bacterial species cultured from soil should be identified. Maybe you could specify your question and describe if you want to identify a single culturable bacterium from soil or to perform metagenomics to identify many bacterial species in parallel.
