The Azolla, Anabaena azollae Relationship: II. Localization of Nitrogenase Activity as Assayed by Acetylene Reduction 1

AUTOR(ES)
RESUMO

Anaerobic (microaerophilic) acetylene reduction by Azolla caroliniana Willd. was dependent on light and saturated at approximately 450 foot candles. Maximum rates of acetylene reduction were 60 nmoles/mg chlorophyll minute. However, rates of 25 to 30 nmoles/mg chlorophyll minute were more common.
