A taxonomic survey was conducted to determine the microbial diversity held within the Harbor Branch Oceanographic Marine Microbial Culture Collection (HBMMCC). The collection consists of approximately 17,000 microbial isolates, with 11,000 from a depth of greater than 150 ft seawater. A total of 2273 heterotrophic bacterial isolates were inventoried using the DNA fingerprinting technique amplif...

Forest floor mineral soil mix (FMM) and peat mineral soil mix (PMM) are cover soils commonly used for upland reclamation post open-pit oil sands mining in northern Alberta, Canada. Coarse woody debris (CWD) can be used to regulate soil temperature and water content, to increase organic matter content, and to create microsites for the establishment of microorganisms and vegetation in upland recl...

BACKGROUND Ischemia-reperfusion (I/R) injury is associated with intestinal microbial dysbiosis. The "gut-liver axis" closely links gut function and liver function in health and disease. Ischemic preconditioning (IPC) has been proven to reduce I/R injury in the surgery. This study aims to explore the effect of IPC on intestinal microbiota and to analyze characteristics of microbial structure shi...

Hydrogenogenic carboxydotrophs may provide hydrogen as primary energy for the microbial community via carbon monoxide oxidation. To investigate the genetics of carbon monoxide metabolism, we report here the draft genome sequences of the hydrogenogenic carboxydotrophs Carboxydocella sp. strains JDF658 (2.60 Mbp; G+C content, 49.2%) and ULO1 (2.70 Mbp; G+C content, 48.8%).

The association between moisture-related microbial growth (mesophilic fungi and bacteria) within insulated exterior walls and microbial concentrations in the indoor air was studied. The studied apartment buildings with precast concrete external walls were situated in a subarctic zone. Actinomycetes in the insulation layer were found to have increased concentrations in the indoor air. The moistu...

Forest management often results in changes in soil microbial communities. To understand how forest management can change microbial communities, we studied soil microbial abundance and community structure in a natural Chamaecyparis (NCP) forest, a disturbed Chamaecyparis (DCP) forest, a secondary (regenerated) Chamaecyparis (SCP) forest and a secondary (reforested) Cryptomeria (SCD) forest. We a...

Introduction: Maintaining good oral hygiene is an important factor in health.Toothbrushes are commonly used to maintain oral health and prevent dental disease, but unfortunately how keeping the toothbrush is neglected . The aim of this study was to investigate the relationship between toothbrush keeping method and its microbial content. Methods: In this cross-sectional study, 60 volunteers w...

sour cherry is one of the most important horticultural products in iran that consumes as fresh and dried fruit. in this research the effect of osmotic pretreatment on physicochemical, antioxiative and microbial characteristics of 4 cultivars of sour cherry: early jibilium, butermo, sigany and local were investigated. the samples were placed in different osmotic solution, dried and vacuum packed...
