灰帶藍麴黴(學名Aspergillus glaucus)為髮菌科麴菌屬下的一個種。為一種絲狀真菌,由於其在極端環境下的生理耐受度高,因此具有廣泛的環境分佈。[1][2]像許多其他麴菌屬Aspergillus)的真菌一樣,它可以是輕度致病的,但在醫學和食品生產中具有許多潛在應用。[3][4]

形態學

編輯

灰帶藍麴黴是絲狀和壁薄的,與同屬的其他物種有許多共同特徵。其分生孢子頭(conidial heads)為輻射狀,一般大小約在 5 至 6.5 μm 之間。產生分生孢子之細胞(conidiogenous)形狀為圓柱形,分生孢子(conidium)為圓形或橢圓形。[5][6]分生孢子梗(conidiophores)通常長 200 至 350 μm ,其壁平滑,在無色至淡褐色之間。菌絲(hyphae)是有分隔且透明的。[7]瓶梗(phialides)覆蓋囊泡(vesicles)的上部,為球狀至亞球狀,單列,直徑在 15 至 30 μm 之間。子囊(asci)包含八個孢子,通常為不規則,而子囊殼(perithecia)通常是黃色的。其黴菌外觀常可見黃色或綠色斑塊。[5]

習性與生長環境

編輯

由於其生理上的特徵,灰帶藍麴黴是一種非常強壯的嗜旱真菌(xerophilic fungus),可於各種不同的環境中存活。此種能夠在低濕度環境中生長,也能夠在乾燥地區生長。其可生長溫度範圍為 4°C至 37°C,因此在冬季它也能生長良好,亦是少數可發現於北極地區的真菌之一。然而,生長的最佳溫度範圍在 24°C和 25°C之間,這個溫度範圍被認為是最適合生長的,大約會在一到三週內達到成熟。它也是該屬中耐滲透性最強種類之一,能夠在 60% 的蔗糖濃度下發育,也能夠生長在非常甜的糖漿和食品中。[8]

病理

編輯

有些菌株可能產生黴菌毒素(mycotoxins),有實例顯示它會導致致命的腦部感染。[9]雖然如此,它並不被認為是非常致病的,因為它的生長溫度超過 35°C就會被限制。此外,即使作為病原體,也不被認為是高危險的,因為它對抗真菌治療非常敏感。[10]另外,除了引起肺炎(pneumonitis)和各種形式的皮膚炎(dermatitis)之外,它也是已知的過敏原和刺激物。[11][12]

應用

編輯

應用於日本料理中的燻發酵魚片(鰹節)。在製備的最後階段,將其培養物噴灑到魚上,使之發酵。但由於其會產生β-硝基丙酸(beta-nitropropionic acid)毒素,因此一直存在健康問題。[13] 另一種可能的應用是作為抗癌劑的用途,[14][15]其真菌毒素 aspergiolide A 具有作為抗癌劑的潛力。最後,由於其北極棲息地和低基本生長溫度範圍,灰帶藍麴黴為能夠在低溫下發揮功能之酶的潛在來源,儘管該領域的研究還相對較新。[16]
