rhizobial

A new rhizobial species,Bradyrhizobium frederickii, has been named in honor of the late Professor Llyod R. Frederick who was a professor of soil microbiology in the Iowa State Department of Agronomy.

The rhizobial species is a nitrogen-fixing lineage that is isolated from nodules of the caesalpinioid species Chamaecrista fasciculata and is characterized by tolerance to high temperature in vitro.

Padma Somasegaran, PhD and retired microbiologist, knew Professor Frederick for many years when he was with the NifTAL Project at the University of Hawaii Department of Agronomy and Soil Science. At the time, Professor Frederick was with USAID in Washington DC and would frequent Hawaii.
