Growth assay of Synechococcus elongatus PCC 7942 (7942) in incubation with filtrates from wet-ozonized, dry-ozonized, and non-ozonized pine 400 (P400) biochar at different DOC concentrations. A Photographs of multi-well plate with P400 biochar filtrates inoculated with 7942 on day 0, day 4 and day 16 of the growth assay. The photographs shown are one of the two replicates. The setup of the plate is shown in Table 1. B Optical density (OD730) of 7942 after 16 days of incubation with P400 biochar filtrates. The error bars on the graph represent the standard deviation of the 2 multi-well plates (n = 2). The asterisks brackets (*) show significant difference (p < 0.05) between treatments
