A strain of Penicillium expansum was studied for the production of styrene using forest waste biomass as a feeding substrate. The fungal strain was cultivated on bark of various trees supplemented with yeast extract and the volatiles produced were collected on Tenax TA and analyzed by gas chromatography-mass spectrometry. Fungus cultured on grated soft bark of pine (Pinus sylvestris) stems (GPB) and mature bark of oak (Quercus robur) supplemented with yeast extract produced relatively the highest amounts of styrene. The maximum styrene production rate was 52.5 μg/h, 41 μg/h and 27 μg/h from fungus cultivated on 50 mL liquid media with 10 g GPB or mature bark of oak and potato dextrose broth respectively. These promising results suggest that the fungal strain could be used to produce "green" styrene plastics using renewable forest waste biomass.
研究了一株扩展青霉（Penicillium expansum），以森林废弃物生物质为饲养基质生产苯乙烯。将真菌菌株在各种树木的树皮上培养，补充酵母提取物，并在 Tenax TA 上收集产生的挥发物，然后通过气相色谱-质谱法进行分析。在松树（Pinus sylvestris）茎的磨碎软树皮（GPB）和成熟的橡木（Quercus robur）树皮上培养的真菌，并补充酵母提取物，产生的苯乙烯相对最多。从 50 mL 液体培养基中培养的真菌，其最大苯乙烯产量分别为 52.5 μg/h、41 μg/h 和 27 μg/h，所用的液体培养基分别为 10 g GPB 或成熟橡木树皮和马铃薯葡萄糖肉汤。这些有希望的结果表明，该真菌菌株可以用于使用可再生森林废弃物生物质生产“绿色”苯乙烯塑料。
