What microbes do when you change the water in an aquarium

A new paper from Van Bonn et al studies the effect of a water change on the bacterial community of an aquarium. Unfortunately, only the abstract is available openly, but it seems pretty cool: The bacterial community composition and structure of water from an established teleost fish system was examined before, during and after a major water change …

Fish Want Probiotics Too

Researchers in Egypt did a fascinating study recently on probiotics for fish. They tested the effect of three different types of Psuedomonas fluorescens on two pathogens that affect tilapia in the Nile (P. angulliseptica and S. faecium). Their aim was to find a more eco-friendly way of controlling the pathogens in aquaculture compared to chemical antimicrobials. The probiotic was indeed …

New undergraduate research project in the built environment (aquariums) at UC Davis

Last year as part of microBEnet’s mandate to perform outreach associated with the microbiology of the built environment we sponsored and managed an undergraduate research project.   In this we isolated organisms from the built environment and then sequenced several reference genomes.  This work is currently being prepared in a series of genome announcement publications. (see …

Lake Arrowhead Microbial Genomics Meeting 2012: Microbiology of the Built Environment Session

Last night was the Microbiology of the Built Environment session at the bi-annual Lake Arrowhead meeting.  This session was organized and sponsored by microBEnet.  I recorded some of the talks and will post those videos here after some editing. Here’s a summary of the speakers and the topics discussed. The first speaker was James Meadow …

What microbes are lurking in your fish tank? Good candidate for some citizen microbiology I think

Recently I wrote here about a new report on a citizen microbiology effort focusing on microbes in water heaters: More on citizen microbiology project from @Penn_State & @NASA on thermophiles in water heaters via @scicheer @Sci4Cits Well, a new paper in PLoS One (PLoS ONE: Aquarium Nitrification Revisited: Thaumarchaeota Are the Dominant Ammonia Oxidizers in Freshwater …
