Abstract: Stenotrophomonas goyi sp. nov. has been isolated from a contaminated algal culture (Chlamydomonas reinhardtii). Its genome has been fully sequenced (4,487,389 base pairs) and a tentative annotation is provided (4,147 genes). The genome information suggests that S. goyi sp. nov. is unable to use sulfate and nitrate as sulfur and nitrogen sources, respectively. Growth tests have confirmed the dependence of the sulfur-containing amino acids methionine and cysteine. The potential biotechnological interest of this … Show more

A multispecies bacterial community including Microbacterium fakhimi sp. nov., Stenotrophomonas goyi sp. nov., and Bacillus cereus greatly promoted sustained hydrogen production by the microalga Chlamydomonas reinhardtii when cocultivated in mannitol- and yeast extract-containing medium (up to 313 mLxx L-1). Alga viability was also largely prolonged in the cocultures (>45 days) without any nutrient supplementation. Among the bacterial community, Microbacterium fakhimi sp. nov. was the main responsible for the hydrogen production improvement. Nonetheless, the use of the entire bacterial community allowed a better growth of the alga during hydrogen production. Chlamydomonas reinhardtii and Microbacterium fakhimi sp. nov. established a mutualistic association, based on the release of ammonium and acetic acid from the bacterium, while the alga provided sulfur-containing metabolites and complemented the bacterial auxotrophy for biotin and thiamine. This study uncovers the potential of the Chlamydomonas-bacteria consortia for durable and stable H2 production while allowing the simultaneous production of biomass.

Microbacterium fakhimi sp. nov. has been isolated from a contaminated algal culture (Chlamydomonas reinhardtii). Its genome has been fully sequenced (3,753,259 base pairs) and a tentative annotation is provided (3,704 genes). Both, genome information and growth tests suggest that M. fakhimi sp. nov. is auxotroph for biotin and thiamine and unable to use sulfate as sulfur (S) source. S-reduced forms, such as methionine and cysteine can support M. fakhimi sp. nov. growth. The potential biotechnological interest of this bacteria is discussed here and in a related research paper (Fakhimi et al., 2023b).
