Use of a commercial Bacillus subtilis biological indicator for monitoring the effectiveness of formaldehyde fumigation.
A commercially available Bacillus subtilis (subspecies niger) biological indicator system may be adapted for use in monitoring the efficiency of fumigation with formaldehyde gas. Limitations to the efficient functioning of these indicators have been investigated in fumigation trials and the findings have been included in suggestions for usage.
