摘要
研究浓度为0.5 g/L的4种盐Zn(CH3COO)2、CuSO4、FeSO4、CaCl2对5个黑木耳(Auricularia auricula-judae)菌株菌丝生长速度、生物量、酪氨酸酶活力、黑色素产量的影响。结果表明:Zn(CH3COO)2与CuSO4抑制黑木耳菌株菌丝的生长;CaCl2可增加发酵过程中5个菌株的生物量;4种盐均可增加黑木耳菌株青瑞、青灰小碗发酵过程中酪氨酸酶活力,Zn(CH3COO)2抑制菌株黑旺十三发酵过程中酪氨酸酶活力,CuSO4与CaCl2抑制菌株波密发酵过程中酪氨酸酶活力;Zn(CH3COO)2与CaCl2可增加5个黑木耳菌株的黑色素产量。
At the concentration of 0.5 g/L,4 kinds of inorganic salts,Zn(CH3COO)2,CuSO4,FeSO4 and CaCl2,were evaluated for their effects on growth rate,biomass,tyrosinase activity and melanin production of 5 Auricularia auricula-judae strains.The results showed that Zn(CH3COO)2 and CuSO4 inhibited the mycelial growth of the 5 A.auricula-judae strains.Calcium chloride increased the biomass of the 5 strains during fermentation.All 4 kinds of salts enhanced the tyrosinase activity in strains QHXW and QR during fermentation.On the other hand,Zn(CH3COO)2 inhibited the tyrosinase activity in the strain HW-13 during fermentation;and CuSO4 and CaCl2 inhibited tyrosinase activity in the strain BM during fermentation.Calcium chloride and Zn(CH3COO)2 increased the melanin production of the 5 tested A.auricula-judae strains.
