摘要	Concentrated cultures (25-86 mg Chl a l(-1)) of Anabaena variabilis PK84 were incubated under 99% Ar+1% CO2 atmosphere in the photobioreactor made of coaxial cylinders. Under illumination equal to 353 mu E m(-2) s(-1) they produced hydrogen with the rate more than 20 ml l(-1) h(-1) for several days. The efficiency of light energy conversion into H-2 was approx. 1% and did not depend significantly on initial Chl a concentration. H-2/O-2 ratio reached 41.5% of theoretical value for water photolysis. Data indicate that dense cultures might be used for outdoor systems under direct sun light. Supra-optimal temperatures 36 degrees C were not harmful for cultures even for 2 days period. Short-term incubation of cultures under 36 degrees C even increased H2 production rate and efficiency of light energy bioconversion by 1.25 times.
