應對生物膜細菌的耐藥性,主要有兩條思路:一是研發(fā)新的抗生素;二是打碎生物膜,把細菌分割開來。此次,新南威爾士大學的科學家就是用納米微粒打碎了頑固的細菌生物膜。
加利福尼亞大學系統(tǒng)生物學家GürolSüelü,想要弄明白褶皺脊如何生成的。褶皺脊被認為有助于生物膜更有效地交換養(yǎng)分。GürolSüelü和他的同事發(fā)現(xiàn)死細胞積累在脊下,但不知道誰先誰后:細胞死亡還是類似腳手架的結構形成。為解決這個‘蛋與雞’的問題,GürolSüelü和他的同事們首先踏上了‘生物膜上細胞死亡’的探索之路。研究團隊制備了土壤細菌枯草芽孢桿菌的許多突變體。每個突變?nèi)笔б粋€被認為參與生物膜形成的基因。在每一種情況下,研究團隊注意是否基因增強或抑制細胞死亡。研究團隊還追蹤了細胞死亡的時間和地點??偟膩碚f,有一個細胞死亡的固定模式,他們發(fā)現(xiàn):只有特定的細胞補丁會解體。生物圈 是所有生物鏈的一個統(tǒng)稱,他包含了 生物鏈和所有細微的生物和生態(tài)環(huán)境,生態(tài)系統(tǒng)等。
生物圈是地球上zui大的生態(tài)系統(tǒng),也是zui大的生命系統(tǒng)。
生物圈(Biosphere)是指地球上所有生態(tài)系統(tǒng)的統(tǒng)合整體,是地球的一個外層圈,其范圍大約為海平面上下垂直約10公里。它包括地球上有生命存在和由生命過程變化和轉(zhuǎn)變的空氣、陸地、巖石圈和水。從地質(zhì)學的廣義角度上來看生物圈是結合所有生物以及它們之間的關系的性的生態(tài)系統(tǒng),包括生物與巖石圈、水圈和空氣的相互作用。生物圈是一個封閉且能自我調(diào)控的系統(tǒng)。地球是整個宇宙中*已知的有生物生存的地方。一般認為生物圈是從35億年前生命起源后演化而來。地質(zhì)學家愛德華?蘇威斯于1875年zui早使用生物圈這個詞。它本來是一個地質(zhì)學的詞。它顯示了查爾斯?羅伯特?達爾文和馬修? 方丹? 莫里的理論對地球科學的影響。1920年代生物圈這個詞獲得它的生態(tài)意義。1935年生態(tài)系統(tǒng)這個詞被引入。弗拉基米爾?沃納德斯基將生態(tài)學定義為研究生物圈的科學。生物圈這個概念今天集合了天文學、地質(zhì)物理學、氣象學、生物地理學、演化論、地質(zhì)學、地質(zhì)化學、水.
To deal with the biofilm resistance of bacteria, there are two main ideas: First, research and development of new antibiotics; Second, break up the biofilm, the bacteria separated. This time, scientists at the University of New South Wales smashed stubborn bacterial biofilms with nanoparticles.
Gürol Süelü, a systems biologist at the University of California, wants to understand how wrinkle ridges are created. Pleat ridges are believed to help biofilm exchange nutrients more efficiently. Gürol Süelü and his colleagues found that dead cells accumulate under the spine, but do not know who will lead: cell death or scaffolding-like structure. To solve this 'egg and chicken' problem, GürolSüelü and his colleagues first set foot on the road to 'cell death on the biofilm'. The team prepared many mutants of the soil bacterium Bacillus subtilis. Each mutation is missing a gene that is thought to be involved in biofilm formation. In each case, the research team noticed whether the gene is enhancing or inhibiting cell death. The team also tracked when and where cells died. In general, there is a fixed pattern of cell death, and they found that only specific cell patches can break apart. Biosphere is a general term for all biological chains, and it contains the biological chain and all the subtle biological and ecological environments and ecosystems.
The biosphere is the largest ecosystem on earth and the largest living system.
Biosphere refers to the unity of all the ecosystems on the earth. It is an outer circle of the earth and is about 10 km vertically up and down from sea level. It includes air, land, lithosphere and water that exist on Earth and that change and change through the life process. From a geo-general point of view, the biosphere is a global ecosystem that combines all living things and their relationships, including the interaction of living things with lithosphere, hydrosphere and air. The biosphere is a closed and self-regulating system. The Earth is the only place where living things are alive in the entire universe. It is generally believed that the biosphere evolved from the origin of life 3.5 billion years ago. Geologist Edward? Su Weisi in 1875 the earliest use of the word biosphere. It was originally a geology word. It shows the impact of the theories of Charles Robert Darwin and Matthew Fontaine Morey on earth science. The word biosphere of the 1920s gained its ecological significance. The term ecosystem was introduced in 1935. Vladimir Warnadowski defines ecology as the science of research biosphere. The concept of biosphere today integrates astronomy, geophysics, meteorology, biogeography, evolution theory, geology, geochemistry, water.
