Abstract

A microalga Tetraselmis subcordiformis (synonym: Platymonas subcordiformis) based photoanode was prepared by a novel method developed in our lab. In a three-electrode configuration, photocurrent and photosynthetic oxygen evolution were measured synchronously. The effects of three site-specific inhibitors (CCCP, DCMU and DBMIB) on photocurrent response of microalgal photoanode were investigated and discussed. The results indicated that the electrons of photocurrent originated from the photosynthetic electron transfer chain of microalga. In further discussion on specific roles of CCCP during biohydrogen photoproduction from Tetraselmis subcordiformis, it was estimated that CCCP at 15 uM inhibited about 34% of PS II activity as ADRY agent and about 51% of PS II activity as uncoupler.
