Non-human microbiome, July 2014

Kittens! And squid, sponges, acid mine drainage in someone’s backyard, soils, and sediments.

Cat microbiome

KittensDeep Illumina-Based Shotgun Sequencing Reveals Dietary Effects on the Structure and Function of the Fecal Microbiome of Growing Kittens – Oliver Deusch – PLOS ONE

“The present study… applied deep Illumina shotgun sequencing to identify the diet-associated functional potential and analyze taxonomic changes of the feline fecal microbiome.”

Squid microbiome

Squid albaGene-Swapping Mediates Host Specificity among Symbiotic Bacteria in a Beneficial Symbiosis – Alba A. Chavez-Dozal – PLOS ONE

“Our results demonstrate that multiple bacterial genetic elements can determine V. fischeri strain specificity between two closely related squid hosts, indicating how important genetic variation is for regulating conspecific beneficial interactions that are acquired from the environment.”

Sponge microbiome 

Review: Diversity and biotechnological potential of microorganisms associated with marine sponges – Fuerst JA – Applied Microbiol Biotechnol (Direct link not working)

“Here, we review recent progress in our understanding of this genetic diversity, its retrieval via culture and genomic approaches, and its implications for chemical diversity and other biotechnology applications of sponge microorganisms and their genes.”

Soils and sediments

StroudMetal(loid) bioaccessibility dictates microbial community composition in acid sulfate soil horizons and sulfidic drain sediments – Jackie Stroud – Environmental Science & Technology

“Microbial community compositions were determined for three soil horizons and drain sediments within an anthropogenically-disturbed coastal acid sulfate landscape using 16S rRNA gene tagged 454 pyrosequencing.”

“Together these results indicate the potential for heterotrophic carbon metabolism in the reduced sediments, consistent with the proliferation of known heterotrophic taxa (e.g. Pseudomonadaceae, Burkholderiaceae, Clostridiaceae) inferred from 16S rRNA gene pyrosequencing.”

Brantner AMDResponse of Soil-Associated Microbial Communities to Intrusion of Coal Mine-Derived Acid Mine Drainage – Justin S. Brantner and John M. Senko – Environmental Science & Technology

“Evaluation of pyrosequencing-derived 16S rRNA gene sequences recovered from incubations revealed the development of microbial community characteristics that were similar to those of the mature iron mound sediment.”

Screen shot 2014-07-14 at 12.36PM, Jul 14New carbohydrate-active enzymes identified by screening two metagenomic libraries derived from the soil of a winter wheat field – A. Stroobants – Journal of Applied Microbiology

“The aim of this work was to discover new β-glucosidases by constructing two metagenomic DNA libraries from soil samples collected in winter and spring from a field of winter wheat.”
