The experiments were performed in Erlenmeyer flasks and spore suspension was used for inoculation. The results show that the mechanism of dye removal by penicillium terrestre is biosorption and the growing pellets exhibit higher adsorptive capacity than the resting or dead ones. The maximum removals of disperse blue 2BLN, reactive brilliant blue KN-R, acid anthraquinone blue and bromamine acid at the concentration of 120 mg/L by biosorptionof growing pellets are 10096, 100%, 96% and 91%, respectively. The 100.0% and 91.4% KN-R removals are achieved respectively at the much higher concentration of 250 and 400 mg/L. 2.5 g/L glucose is sufficient for 100% KN-R removal by growing pellets. Salinity （NaCl） increase from 0 to 2% （W/ V） moderately accelerates both mycelium growth and KN-R removal.展开更多

Their structures are identified as cyclo （glycyl-D-proline） （1）, cyclo （L-prolyl-L-alanine） （2）, cyclo （L-prolyl- D-alanine） （3）, cyclo （L-leucyl-trans-4-hydroxy-L-proline） （4）, cyclo （L-leucyl-cis-4-hydroxy-D-proline） （5）, cyclo （L-trans-（4- hydroxyprolinyl）-L-phenylalanine） （6）, hexylitaconic acid （7）, and hexylitaconic methylate （8）, based on spectroscopic analysis （1D, 2D NMR）. Compounds 7, 8 were obtained from the genus Penicillium for the first time, while compounds 1-6 were isolated from the fungus Penicillium terrestre for the first time.展开更多
