Microbes and humans Review: The Anthropocene: a conspicuous stratigraphical signal of anthropogenic changes in production and consumption across the biosphere – Mark Williams – Earth’s Future (OA) Biospheric relationships between production and consumption of biomass have been resilient to changes in the Earth system over billions of years. This relationship has increased in its complexity, …

New papers on microbiology of the built environment, February 20, 2016

Set in stone Commentary: Making microbiology of the built environment relevant to design – G. Z. Brown, Jeff Kline, Gwynne Mhuireach, Dale Northcutt and Jason Stenson – Microbiome (OA) Architects are enthusiastic about “bioinformed design” as occupant well-being is a primary measure of architectural success. However, architects are also under mounting pressure to create more sustainable …

Microbes Corroding Concrete

A recent study form Ling et al explored microbial community succession on concrete. They examined the concrete in two sewage manholes over a year using 16S rRNA sequencing. Concrete is a huge part of urban environments, and corrosive microbes eat it away. This causes structural damage, which is especially unwanted in sewage systems. The abstract for the …

Paper on Microbially Induced Concrete Corrosion

Back in May we posted about a Gizmodo article entitled “Concrete-Dissolving Bacteria Are Destroying Our Nation’s Sewers”.  This article highlighted Sloan-funded work by Mark Hernandez and others that describes some of the biochemistry and microbiology behind concrete corrosion in sewers.   A (fee-required) paper describing that work has just come out, with a press release focused …

“Living alternative to concrete”

Interesting article about a “living alternative to concrete”.  Ignoring the fact that the final product is not actually living, this is a pretty cool idea.  This product uses bacteria to produce a concrete-like substance using much less energy than traditional methods.  A number of similar ideas are the in the works including mushroom-grown bricks.   Some …
