The utility model discloses a test kit for coliform bacteria in water. The test kit comprises a kit body (1), wherein the opening of the kit body (1) is sealed by a sealing film (4), the sealing film (4) and the kit body (1) form the sealed kit body, the kit body (1) ...
Candidate phyla radiation (CPR) bacteria and DPANN archaea are unisolated, small-celled symbionts that are often detected in groundwater. The effects of groundwater geochemistry on the abundance, distribution, taxonomic diversity and host association of
Herein, we describe an AMF-manipulated tumor-homing bacteria (AMF-Bac), constructed by modifying genetically engineeredE. coli BL21attenuated strain with a Fe3O4@lipid nanocomposite. We modularly design and fabricate the AMF-Bac utilizing both genetic engineering and nanotechnology. Similar to machiner...
Groundwater of the very shallow well H14, located uphill of the transect, shows a fast response to weather events [62], and is characterized by both the highest bacterial diversity and the presence of well-known surface heterotrophs; whereas core groundwater species dominated groundwater microbiome...
The microbial DNA of golden pompano intestine and tank water was extracted using EZNA Stool DNA Kit (Omega Bio-tek). The V3–V4 region of bacteria 16S ribosomal RNA gene was amplified by PCR using the primers V338F (5′-ACTCCTACGGGAGGCAGCAG-3′) and V806R (5′-GGACTACHVGGGTWTCTAAT-...

Psychrotrophic lactic acid bacteria (LAB) species are the dominant species in the microbiota of cold-stored modified-atmosphere-packaged food products and are the main cause of food spoilage. Despite the importance of psychrotrophic LAB, their response t
Singapore) in 25 μl aliquots containing 12.5 μl of PCR Master Mix (BIOLINE, Meridian Life Science Inc, USA), 1 μl of forward primer, 1 μl of reverse primer (each primer of 10 pmol), 1 μl of 100 ng/μl DNA and RNase-free water to final volume of 25 μ...
(predominantly adapted to marine water environments) were enriched and grown as planktonic cells in membrane bioreactors (Supplementary Fig.1a)15. Fluorescence in situ hybridization (FISH) showed that the anammox bacteria constituted >95% of the bioreactor’s community (Supplementary Fig.1b–g). ...
The water in this chamber acts as the coupling medium to transfer the ultrasound wave from the transducer to the tumor. To measure the internal tumor temperature during a heating session we temporarily implant a thin fiber optic temperature probe (Neoptix, T1) into the tumor. The custom-ordered...
