Incubate suspension at 37 °C for 6 h to overnight in a water bath. Note: In case of fast-growing mycobacteria such as Mycobacterium smegmatis (M. smegmatis), go directly to step 7. However, if DNA is to be isolated from slow-growing species, follow steps 4-6 which involve lysis of cells by a physical method. Because of enhanced disruption of cells, this would significantly enhance yield.""" ; applan:Step ; bs:bioSampleUsedsub:_1 ; bs:labEquipmentUsedobo:OBI_0400155 ; bs:reagentUsedsub:_2 . }
