O2 consumption on a larger scale could be achieved with co cultures of bacteria and microalgae that improve the H2 production, like: C. reinhardtii and Bradyrhizobium japonicum, C. reinhardtii with Stenotrophomonas, Microbacterium and Pseudomonas, and Chlamydomonas sp. MACC-549 and C.
reinhardtii cc124 with Brevundimonas, Rhodococcus, and Leifsonia.
