The Jefferson Memorialome? The Jeffersonome? The Jefferson Microbiome? A biofilm by any other name …

Who wants a new project?  Seems like they could use some microbiology of the built environment experts to provide additional help on this one:  Officials fret as fungi, algae and bacteria leave growing stains on hallowed stone. Source: A grimy, black biofilm is starting to cover the Jefferson Memorial, and it can’t be killed – …

Microbes in the air High throughput genomic sequencing of bioaerosols in broiler chicken production facilities – Kate M. O’Brien – Microbial Biotechnology (OA) Chronic inhalation exposure to agricultural dust promotes the development of chronic respiratory diseases among poultry workers. Poultry dust is composed of dander, chicken feed, litter bedding and microbes. However, the microbial composition …

Cyanobacteria cells act as tiny spherical lenses

While it has long been known that some cyanobacteria move (or crawl) towards light, how these cells detect the direction and source of light was undescribed until recently. In Cyanobacteria use micro-optics to sense light direction, Schuergers et al. (2016) investigated Synechocystis phototaxis and found that each cell acts as a microscopic spherical lens, focusing an intense light spot close to the opposite side …

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 …
