摘要

在白松铜矿的一个废弃隧道深处，在固定的盐水池中发现了铜- oh - cl矿物atatacamite和paratacamite的绿色薄膜。一些水池还覆盖了一层薄薄的石油。绿膜由平均直径为20 μm的单个气泡和革兰氏阴性菌、短杆状菌和鞘状丝状菌的混合菌落组成。atacamite-paratacamite混合物中的碳δ13C值反映了细菌和少量石油与矿物混合的同位素值。异养细菌被解释为以石油为碳源，可能催化羟基氯化铜矿物的沉淀或作为模板。

Geochemistry and Microbiology of Atacamite-Paratacamite Biofilms Floating on Underground Brine and Petroleum Pools in the White Pine Copper Mine, Michigan (USA)

At depth in an abandoned tunnel of the White Pine Copper Mine, green films of the Cu-OH-Cl minerals atacamite and paratacamite were found on standing pools of brine. Some pools were also coated with a thin layer of petroleum. Green films of atacamite were composed of individual blebs that averaged 20 μm in diameter and enclosed mixed colonies of Gram-negative, short rod-shaped, and sheathed filamentous bacteria. Carbon δ13C values in the atacamite–paratacamite mixtures reflect the isotopic values of bacteria and minor amounts of petroleum mixed with the minerals. Heterotrophic bacteria are interpreted to be using petroleum as a carbon source and may be catalyzing the precipitation of the copper hydroxy chloride minerals or acting as a template.

期刊介绍： Micro & Nano Letters offers express online publication of short research papers containing the latest advances in miniature and ultraminiature structures and systems. With an average of six weeks to decision, and publication online in advance of each issue, Micro & Nano Letters offers a rapid route for the international dissemination of high quality research findings from both the micro and nano communities. Scope Micro & Nano Letters offers express online publication of short research papers containing the latest advances in micro and nano-scale science, engineering and technology, with at least one dimension ranging from micrometers to nanometers. Micro & Nano Letters offers readers high-quality original research from both the micro and nano communities, and the materials and devices communities. Bridging this gap between materials science and micro and nano-scale devices, Micro & Nano Letters addresses issues in the disciplines of engineering, physical, chemical, and biological science. It places particular emphasis on cross-disciplinary activities and applications. Typical topics include: Micro and nanostructures for the device communities MEMS and NEMS Modelling, simulation and realisation of micro and nanoscale structures, devices and systems, with comparisons to experimental data Synthesis and processing Micro and nano-photonics Molecular machines, circuits and self-assembly Organic and inorganic micro and nanostructures Micro and nano-fluidics
