灰带蓝曲霉(学名:Aspergillus glaucus)为发菌科麹菌属下的一个种。为一种丝状真菌,由于其在极端环境下的生理耐受度高,因此具有广泛的环境分布。[1][2]像许多其他麹菌属(Aspergillus)的真菌一样,它可以是轻度致病的,但在医学和食品生产中具有许多潜在应用。[3][4]
形态学
[编辑]灰带蓝曲霉是丝状和壁薄的,与同属的其他物种有许多共同特征。其分生孢子头(conidial heads)为辐射状,一般大小约在 5 至 6.5 μm 之间。产生分生孢子之细胞(conidiogenous)形状为圆柱形,分生孢子(conidium)为圆形或椭圆形。[5][6]分生孢子梗(conidiophores)通常长 200 至 350 μm ,其壁平滑,在无色至淡褐色之间。菌丝(hyphae)是有分隔且透明的。[7]瓶梗(phialides)覆盖囊泡(vesicles)的上部,为球状至亚球状,单列,直径在 15 至 30 μm 之间。子囊(asci)包含八个孢子,通常为不规则,而子囊壳(perithecia)通常是黄色的。其霉菌外观常可见黄色或绿色斑块。[5]
习性与生长环境
[编辑]由于其生理上的特征,灰带蓝曲霉是一种非常强壮的嗜旱真菌(xerophilic fungus),可于各种不同的环境中存活。此种能够在低湿度环境中生长,也能够在干燥地区生长。其可生长温度范围为 4°C至 37°C,因此在冬季它也能生长良好,亦是少数可发现于北极地区的真菌之一。然而,生长的最佳温度范围在 24°C和 25°C之间,这个温度范围被认为是最适合生长的,大约会在一到三周内达到成熟。它也是该属中耐渗透性最强种类之一,能够在 60% 的蔗糖浓度下发育,也能够生长在非常甜的糖浆和食品中。[8]
病理
[编辑]有些菌株可能产生霉菌毒素(mycotoxins),有实例显示它会导致致命的脑部感染。[9]虽然如此,它并不被认为是非常致病的,因为它的生长温度超过 35°C就会被限制。此外,即使作为病原体,也不被认为是高危险的,因为它对抗真菌治疗非常敏感。[10]另外,除了引起肺炎(pneumonitis)和各种形式的皮肤炎(dermatitis)之外,它也是已知的过敏原和刺激物。[11][12]
应用
[编辑]应用于日本料理中的熏发酵鱼片(鲣节)。在制备的最后阶段,将其培养物喷洒到鱼上,使之发酵。但由于其会产生β-硝基丙酸(beta-nitropropionic acid)毒素,因此一直存在健康问题。[13] 另一种可能的应用是作为抗癌剂的用途,[14][15]其真菌毒素 aspergiolide A 具有作为抗癌剂的潜力。最后,由于其北极栖息地和低基本生长温度范围,灰带蓝曲霉为能够在低温下发挥功能之酶的潜在来源,尽管该领域的研究还相对较新。[16]
