  1. The lignin used was depolymerized with two different flow rates (5 and 10 mL/min) and three different severities (190, 220, 240 °C) for each flow rate. The plates were incubated for 3 weeks at 30 °C. The isolates were previously tentatively reported as Pseudomonas sp. (B); P. plecoglossicida (C); P. deceptionensis (9.1); and Rhodococcus erythropolis (19). Biological duplicates are indicated as 1 and 2. (+ growth; − no growth)
