Non-human microbiome, July 21

Microbiomes of water fleas, marine zooplankton, soil, rumen, and how a microbiome can help woodrats eat toxic plants.

Rumen microbiome

Development of a phylogenetic microarray for comprehensive analysis of ruminal bacterial communities – M. Kim – Journal of Applied Microbiology

“A total of 1,666 OTU-specific probes were designed and synthesized on microarray slides (referred to as RumenBactArray) in a 6×5k format with each probe being represented in triplicate.”

Rodent microbiome

Gut microbes of mammalian herbivores facilitate intake of plant toxins – Kevin D. Kohl – Ecology Letters

“We investigated the gut microbiota of desert woodrats (Neotoma lepida), some populations of which specialise on highly toxic creosote bush (Larrea tridentata). Here, we demonstrate that gut microbes are crucial in allowing herbivores to consume toxic plants. “

Crustacean microbiome

Water fleas require microbiota for survival, growth and reproduction – Marilou P Sison-Mangus – ISME Journal

“We assessed the effect of microbiota on Daphnia magna by experimentally depriving animals of their microbiota and comparing their growth, survival and fecundity to that of their bacteria-bearing counterparts.”

Soil microbiome

Soil Properties and Spatial Processes Influence Bacterial Metacommunities within a Grassland Restoration Experiment – Cheryl A. Murphy – Restoration Ecology

“We found that soil bacterial communities were not influenced by plant restoration, but rather, by the local heterogeneity of soil environmental properties (16.9% of bacterial community variation) and pure spatial effects (11.1%).”

Environmental drivers of soil microbial community distribution at the Koiliaris Critical Zone Observatory – Myrto Tsiknia – FEMS Microbiology Ecology

“This study investigates the distribution of archaea, bacteria and fungi as well as the dominant bacterial phyla (Acidobacteria, Actinobacteria, Bacteroidetes, Firmicutes), and classes of Proteobacteria (α- and β-Proteobacteria) across the Koiliaris watershed by qPCR and associate them with environmental variables. “

Soil microbial community structure and activity along a montane elevational gradient on the Tibetan Plateau – Meng Xu – European Journal of Soil Biology

“We investigated the microbial community composition and functional patterns along an elevational gradient (3100–4600 m above sea level) on Mount Segrila using phospholipid fatty acids (PLFAs) and community level physiological profiles (CLPP). “

Oil pipeline microbiome

Identification and characterization of microbial biofilm communities associated with corroded oil pipeline surfaces – Tiffany R. Lenhart – The Journal of Bioadhesion and Biofilm Research

“Eubacterial and archaeal 16S rRNA sequences of DNA recovered from extracted pipeline pieces, termed ‘cookies,’ revealed the presence of thermophilic sulfidogenic anaerobes, as well as mesophilic aerobes. “

Plankton microbiome

Zooplankton diversity across three Red Sea reefs using pyrosequencing – John K. Pearman – Frontiers in Marine Science

“The diversity of metazoan plankton was investigated by targeting the 18S rRNA gene and clustering OTUs at 97% sequence similarity. A total of 754 and 854 metazoan OTUs were observed in the data set for the 1380F and 1389F primer sets respectively. “

Food microbiology

Cheese Rind Communities Provide Tractable Systems for In Situ and In Vitro Studies of Microbial Diversity – Benjamin E. Wolfe – Cell

“Sequencing of 137 different rind communities across 10 countries revealed 24 widely distributed and culturable genera of bacteria and fungi as dominant community members. “
