Table 2 Comparison of co-cultivation of microalgae with bacteria to their axenic/control conditions for the improvement in biomass and growth

From: Pelagibaca bermudensis promotes biofuel competence of Tetraselmis striata in a broad range of abiotic stressors: dynamics of quorum-sensing precursors and strategic improvement in lipid productivity

Co-cultivation Fold increase in biomass productivity, growth rate, biomass, or cell size Media References
Chlamydomonas reinhardtii, Chlorella vulgaris, and Scenedesmus with growth promoting bacteria Increment of specific growth rate of 1.13-fold in C. reinhardtii, 1.08-fold in C. vulgaris and 1.10-fold in Scenedesmus sp. BG11 and TAP medium at 30 °C for 12 days with a light intensity of 50 μE m−2 s−1 [58]
Chlorella vulgaris with Rhizobium and Flavobacterium 1.92–2.55-fold increment in cell mass. 1.25-fold increment in lipid content BG-11 (constant stirring at 100 rpm, 25 °C, light intensity of 100 μmol m−2 s−1) [59]
Chlorella vulgaris with beneficial bacteria Duganella sp. JPPB B33 (GU368376) and Pseudomonas putida strain MM1 (AY623928) with some other uncultured bacteria Both increment and decrement of biomass productivity due to the influence of uncultured bacteria Wastewater medium with varying bacterial treatments [60]
Ankistrodesmus and Rhizobium 1.29-fold increment in biomass concentration in bubble photobioreactor. 1.19-fold increment in airlift photobioreactor (dry weight) AEX medium; in air bubble photobioreactor [61]
Botryococcus braunii and Candidatus Phycosocius bacilliformis 1.8-fold in the biomass and 1.5-fold improvement in total hydrocarbon yield Vitamin containing modified media of TSP [62]
Microbacterium sp. and Chlorella vulgaris 1.66-fold increment in biomass (cell dry weight) Modified MBG medium [63]
Acidovorax facilis and Scenedesmus obliquus 1.24-fold in biomass productivity and 1.29-fold in lipid productivity BG 11 medium [64]
Chlorella and Azospirillum brasilense Increased the cell size up to 1.62-fold in Chlorella vulgaris, and total lipid yield increased up to 1.5–3.8 times in varying Chlorella spp. Sterile mineral medium (C30) and co-cultivated in the alginate beads [65]
Chlorella and Azospirillum brasilense 2.1-fold in fresh weight and 24-fold increase in the dry weight of alginate beads containing the per gram of microbial biomass Residual water medium (synthetic wastewater medium) and co-cultivated in alginate beads [66]
Stappia sp., Pelagibaca bermudensis and Tetraselmis striata 1.5–2-fold improvement in biomass productivity O3 Media with higher T. striata concentration as inoculation [12]
P. bermudensis and T. striata 1.2–3-fold improvement in biomass productivity in varying stressors; 1.5-fold improvement in lipid productivity O3 media with varying physicochemical conditions This study
