放線菌ストレプトマイセス・アベルミチリス (Streptomyces avermitilis) 放射菌は菌糸を形成して細長く増殖するという特徴があり、その様子を捉えた映像です。

ところでこの放射菌は抗生物質と大変関係があります。抗生物質とは、微生物が細菌などから身を守るために作るものですが、今の抗生物質の大半は放射菌から作られており、今回のStreptomyces avermitilisからもエバーメクチンという抗寄生虫薬の原料が作り出されることで有名です。

الرائحة الجميلة التي نشمها بعد تساقط الأمطار، سببها بكتيريا! هي بكتيريا (أكتينوميستيس- Actinomycetes) التي تنتشر في تربة الكرة الأرضية في الظروف الرطبة، وعندما تجف التربة فأنها تطلق أبَوْاغ (Spores) في التربة. تلك الأبواغ عند تساقط المطر تنتقل للهواء مسببة الرائحة المحببة للنفس التي نستمتع بها عند وبعد تساقط الأمطار.

Purification and analysis of secondary metabolites from actinomycetes isolated from red soil: Insights into their therapeutic application

Actinomycetes, isolated from soil can produce diverse secondary metabolites with valuable therapeutic applications. This study aimed to isolate actinomycetes from red soil and evaluate their antibacterial, antioxidant, and biofilm-forming potential. Selected isolates exhibited significant antibacterial activity against Gram-positive bacteria in agar well diffusion assays. Further chemical characterization of their secondary metabolites using spectroscopic techniques confirmed the presence of functional groups responsible for their bioactivity. Antioxidant activity was assessed using free radical scavenging assays, revealing strong antioxidant capacity. Additionally, the isolates demonstrated notable biofilm-forming ability, essential for their survival in harsh environments, and may contribute to antibiotic resistance. These soil-derived actinomycetes’ combined antibacterial and antioxidant properties highlight their potential as sources of natural compounds for pharmaceutical applications. The findings support the need for further studies on these bioactive compounds’ toxicity, formulation, and clinical relevance. This research contributes to the growing interest in natural product discovery and provides promising candidates for developing alternative antimicrobial and antioxidant agents from red soil actinomycetes.

This 'supercluster' of a rare soil microbe could produce amazing new drugs

This ‘supercluster’ of a rare soil microbe could produce amazing new drugs

The search for potentially potent new therapeutic molecules in nature is a vital quest driven by parallel health crises: antibacterial resistance and the growing global cancer burden. Now, a team of scientists has discovered that a rare soil microbe produces peculiar but familiar molecular “building blocks” with drug-like activity. This could be a boon for drug design and discovery…
