V. KEY TO THE SUB-GROUPS OF LIQUID MEDIA. 



Group I (Med. 1-1394) 1 



A. Sub-group lA. Water only as a basal medium 1 



B. Sub-group IB. Key to sections of liquid media in which ail constituents 



are inorganic. (Med. 2-113) 3 



1. Nitrogen present as free N2 only. 



a. Incomplete "basal" solutions requiring addition of other nutri- 



ents. Section 1 (Med. 2-25) 3 



b. Complete nutrient solutions.
