MicrobiologySerialDilution
1. An undiluted (stock) solution is termed the 100 dilution. This may be a chemical solution, or a suspension of bacteria or bacteriophage.2. Typical diluions are 10-fold dilutions; each dilution is 1/10th the concentration of the previous dilution. The first 10-fold dilution is termed the 10-1 dilution.3. Each subsequent dilution is made from a previous dilution. Here is a series of 10-fold dilutions: Star......閱讀全文

Trends-in-Microbiology:那些被吃進去的益生菌
腸道微生物群是存在人體腸道的微生物群體的總稱,其中包括了細菌、真菌、古菌以及原生物動植物(甚至病毒)等種類眾多的微生物。由于測序技術的提高,近二十年來,科學界越來越關注腸道微生物菌群。 也有很多的證據表明,腸道微生物菌群對于人體的健康有著很大影響。這種影響不僅局限于腸道,還可能對大腦、肝臟這樣

Environmental-Microbiology:天然抗癌藥物的真正起源
幾十年來,科學家已經知道ET? -743是一種從海洋無脊椎動物中提取的稱為被囊紅樹蝰的藥物,該藥物可以殺死癌細胞。在歐洲和美國臨床試驗中該藥物已經批準用于病人。科學家們懷疑紅樹蝰被囊動物是一種海鞘類生物,實際上并不能生產ET? -743。但該藥(曲貝替丁)的確切起源仍是一個謎。 通過使用先進的
《Nature-Microbiology》發表合成生物學研究新工具
過去17年里,科學家和工程師們開發了可編程的功能性活細胞合成基因電路。類似無數電子產品的集成電路,人工基因電路也能生成自定義動態、再接內生網絡、感知環境刺激、生產有價值的生物分子。 合成生物學在醫學和生物技術領域的應用前景非常廣泛,例如狙擊超級病菌、生產高級生物原料、制造先進功能性材料等等。
Nature-Microbiology:為什么某些EB病毒會引起癌癥?
EB病毒(EBV)非常廣泛。世界上90%以上的人口受到感染,后果各不相同。雖然這種感染通常不會感染人類,但在某些情況下,它會導致腺熱或各種癌癥。德國癌癥研究中心(DKFZ)的研究人員現在已經發現了為什么不同的病毒株會導致非常不同的病程。 超過90%的人在一生中感染了EB病毒,但感染通常不會被發
Microbiology:發現可將植物廢料直接變成柴油的真菌
一種能將植物廢料直接變成柴油的真菌可以讓我們不消耗糧食的情況下生產出生物燃料。這種真菌就是美國科學家在巴塔哥尼亞的雨林樹木中發現的,叫粉紅粘帚霉。它可以讓柴油變成氣體,較液體燃料更加容易提煉、純化和貯存。 發現此真菌的美國蒙大納州大學保茲曼分校的加里·斯托貝爾說:“地球上沒有其它已知生物能做到這個
