The Built Aquatic Environment-

“If there is magic on this planet, it is contained in water” -Loren Eiseley- Aquatic ecosystems can be placed into two discrete categories, native and managed. Native aquatic ecosystems may be influenced by human activities, in fact we’d be hard-pressed to find one that isn’t, but there is no intention to the influence. Managed aquatic …

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 …

I love that @eLIFE is publishing draft papers now (brewery microbiome)

OK that was deceptive of me.  This is not a draft paper.  But it is a paper about drafts – beer that is:  Mapping microbial ecosystems and spoilage-gene flow in breweries highlights patterns of contamination and resistance | eLife. And, well, I am a bit biased since it came from UC Davis colleagues, but it …

Microbial sampling in building surveys: what and why are we sampling?

Following the last posts about sampling in buildings and other man-made environments, I would like to share the paper I will present at Healthy Buildings 2015 Europe. The paper mainly focuses on sampling advice for practitioners, but we have also tried to explain what the concept of «building microbiome» means to us. Although buildings are not living …

Acquired Resistance to Ultraviolet Germicidal Irradiation

By Amanda Makowiecki Miller Research Group University of Colorado, Boulder With drug resistant bacteria becoming a growing problem, alternative methods are being pursued to decontaminate air and surfaces; ultraviolet germicidal irradiation (UVGI) is one of these methods. UVGI uses short wavelength light in order to disrupt the genetic material of microorganisms, this disruption either kills …

Using Sewage to Estimate a City’s Gut Health?

A recent paper by Newton et al compares the microbial community composition in human stool to that of the sewage sludge that it inevitably ends up in. And surprise! The communities looked really similar. Sewage species recaptured most of the human stool species, and was essentially a medley of various gut microbes. The really cool part is how the …
