菌類学菌類学とは
環境科学環境科学
バイオケミストリーバイオケミストリー

背景:

菌類の代謝過程は多様ですが,一酸化炭素 (CO) のような大気ガスへのその貢献はほとんど未知のものです.
CO生成に関する以前の理解は,主に燃焼と特定の細菌の活動に焦点を当てていた.

研究の目的:

食用キノコが代謝の副産物として一酸化炭素 (CO) を生成する可能性を調査する.
菌類によるCO生成が,細菌,光,または酸素濃度などの外部要因に依存しているかどうかを判断する.

主な方法:

60日間で複数の真菌種 (Lentinula edodes, Pleurotus ostreatus, Pleurotus eryngii) から発生したCOおよびCO2排出量の体系的な測定.
様々な基板 (バーク,アルダー,アスペン) を利用し,制御された成長条件.
細菌の関与を排除するために顕微鏡 (光,SEM,TEM) を採用し,排出量の定量化のためにガス分析技術 (ガス分析機,GC-MS) を採用する.

主要な成果:

食用キノコは,細菌の存在,照明,または酸素の制限にかかわらず,一酸化炭素 (CO) を生成することが実証されています.
CO排出量はパラボリック曲線に沿って,CO2レベルと相関し,完全な菌糸体植民期中にピークに達しました.
レンティヌラ・エドデス (Lentinula edodes) (シタケ) は,の木の基板で,他の種や基板と比較して,最も高いCO放出率を示した.

結論:

菌類の呼吸は,これまで認識されていたよりも,大気中のCOダイナミクスに大きく貢献しています.
この発見は,真菌によるCO生成の生化学的メカニズムに関するさらなる研究を必要とします.
菌類の栽培環境における環境モニタリングと労働衛生への影響については,調査が必要である.

Fungal Group Zygomycota

1.5K

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Overview of Fungi

2.0K

Fungi are a diverse group of eukaryotes more closely related to animals than other eukaryotes. Fungal cell walls comprise chitin, a polysaccharide that provides structural strength, and glucans, which contribute to flexibility and integrity. Other polysaccharides, such as mannans and galactosans, may supplement or replace chitin in some fungi. These adaptations, along with their preference for acidic environments and tolerance for high osmotic pressure, enable fungi to thrive in various...

Fungal Phylum Basidiomycota

1.3K

Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

Fates of Pyruvate

11.2K

Pyruvate is the end product of glycolysis, where glucose is oxidized to pyruvate, simultaneously reducing NAD+ to NADH. Two molecules of ATP are also produced by substrate-level phosphorylation.
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...

Fermentation is a crucial anaerobic metabolic process that enables microbes to derive energy from sugar without relying on oxygen or an electron transport chain. This process is fundamental to various biological and industrial applications and is classified based on the metabolic products generated.Role of Pyruvate in FermentationPyruvate and its derivatives serve as key electron acceptors in fermentative pathways. The oxidation of NADH to regenerate NAD+ is essential for the continuation of...
