Inhibition of growth by NO. The table depicts the number of homologs of the flavohaemoglobin genes (fhbA and fhbB), the P450 nitric oxide reductase, and the S-nitrosoglutathione (GSNO) reductase in each species. Strains are listed in the same order as in the phylogenetic tree shown in Fig. 1. Strains were grown in the presence or in the absence of the NO-releasing compound nitroprusside. Growth was monitored at different time intervals. The graph shows the percentage of growth in the presence of 128 mM nitroprusside compared to the control samples grown in the absence of nitroprusside. The time and temperature of growth was optimized for each strain and it was as follows (species name, strain, temperature, and incubation time for growth inhibition calculation): A. glaucus: 22 °C for 72 h; A. tubingensis: 30 °C for 96 h; A. zonatus: 30 °C for 96 h; A. brasiliensis: 30 °C for 72 h; A. versicolor: 30 °C for 96 h; A. sydowii: 30 °C for 96 h; A. niger ATCC1015: 30 °C for 48 h; A. luchuensis: 30 °C for 72 h; A. niger NRRL3: 30 °C for 72 h; A. wentii: 30 °C for 96 h; A. niger CBS 513.88: 30 °C for 96 h; A. fischeri: 30 °C for 96 h; A. terreus: 30 °C for 96 h; A. flavus: 30 °C for 96 h; A. fumigatus: 30 °C for 96 h; A. clavatus: 30 °C for 96 h; A. nidulans: 30 °C for 96 h; A. carbonarius: 30 °C for 72 h; A. aculeatus: 30 °C for 96 h
