    Lytic viral infection and programmed cell death (PCD) are thought to represent two distinct death mechanisms in phytoplankton, unicellular photoautotrophs that drift with ocean currents. PCD (apoptosis) is mainly brought about by the activation of caspases, a protease family with unique substrate selectivity. Here, we demonstrated that virus infection induced apoptosis of marine coccolithophorid Emiliania huxleyi BOF92 involving activation of metacaspase. Read More

    The interaction of copper ions with Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli: an X-ray absorption near-edge structure (XANES) spectroscopy study.

    The antimicrobial properties of copper ions have been known for a long time. However, the exact mechanism of action of the transition metal on microorganisms has long been unclear. X-ray absorption near-edge structure (XANES) spectroscopy at the Cu K edge allows the determination of copper speciation in Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa that have been treated with Cu(II) and Cu(I) solutions.

    Effect of Lactobacillus rhamnosus on the response of Galleria mellonella against Staphylococcus aureus and Escherichia coli infections.
    Arch Microbiol 2017 Nov 24. Epub 2017 Nov 24.
    Department of Biosciences and Oral Diagnosis, Laboratory of Microbiology and Immunology, Institute of Science and Technology, Paulista State University/UNESP, Av, Engenheiro Francisco José Longo, 777-Jardim São Dimas, São José dos Campos, SP, 12245-000, Brazil.
    This study evaluated the prophylactic effects of the live or heat-killed probiotic strain Lactobacillus rhamnosus ATCC 7469 in Galleria mellonella, inoculated with Staphylococcus aureus or Escherichia coli. L. rhamnosus suspension was prepared and a part of it was autoclaved to obtain heat-killed lactobacilli. Read More

    Functional analysis of a regulator of G-protein signaling CgRGS1 in the rubber tree anthracnose fungus Colletotrichum gloeosporioides.

    Institute of Tropical Agriculture and Forestry, Hainan University, Haikou, 570228, China.
    Colletotrichum gloeosporioides is the causal agent of rubber anthracnose, which is also one of the important biological factors threatening the development of natural rubber industry in the world. Regulators of G-protein signaling (RGS) are key negative regulators of G-proteins, which play important roles in growth, development and pathogenic processes of plant pathogens. In this study, a RGS gene CgRGS1 was functionally characterized in C. Read More

    First report of a symbiotic relationship between Xenorhabdus griffiniae and an unknown Steinernema from South Africa.

    Department of Microbiology, University of Stellenbosch, Private Bag X1, Matieland, 7602, South Africa.
    Strain WS9, a mutualistic-associated bacterium, was isolated from an unknown entomopathogenic Steinernema nematode, collected from a litchi orchard in Friedenheim, Mpumalanga, South Africa. Based on phenotypic and phylogenetic data of the 16S rRNA, gltX, recA, dnaN, gyrB and infB gene sequences, strain WS9 is identified as X. griffiniae. Read More

    Caenispirillum humi sp. nov., a bacterium isolated from the soil of Korean pine garden.

    Department of Food and Nutrition, College of Biotechnology and Natural Resource, Chung-Ang University, Anseong-si, Gyeonggi-do, 17546, Republic of Korea.
    A novel bacterial strain MAH-8was isolated from a soil sample of a Korean pine garden and was characterized using a polyphasic approach. Cells were Gram-staining negative, pinkish yellow colored, motile and vibrio-shaped. The strain was aerobic and catalase, oxidase positive, optimum growth temperature and pH were 28-30 °C and 7.

    Phylogenetic diversity and distribution of bacterial and archaeal amoA genes in the East China Sea during spring.

    Microbial nitrification is a key process in the nitrogen cycle in the continental shelf ecosystems. The genotype compositions and abundance of the ammonia monooxygenase gene, amoA, derived from ammonia-oxidizing archaea (AOA) and bacteria (AOB) in two size fractions (2-10 and 0.2-2 µm), were investigated in the East China Sea (ECS) in May 2008 using PCR-denaturing gradient gel electrophoresis (DGGE) and quantitative PCR (qPCR).

    Microbiological and chemical profiles of elephant grass inoculated with and without Lactobacillus plantarum and Pediococcus acidilactici.
    Arch Microbiol 2018 Mar 11;200(2):311-328. Epub 2017 Nov 11.
    Institute of Ensiling and Processing of Grass, Nanjing Agricultural University, Weigang 1, Nanjing, 210095, People's Republic of China.
    The study was conducted to evaluate the microbiological and chemical profiles of elephant grass inoculated with and without different wild strains of lactic acid bacteria. Silage was prepared of four treatments and one control with three replicates as control (EKC, adding 2 ml/kg sterilizing water), Lactobacillus plantarum (USA commercial bacteria) (EKP), Lactobacillus plantarum (EKA), Pediococcus acidilactici (EKB), and Pediococcus acidilactici (SKD) isolated from King grass. Silage were prepared using polyethylene terephthalate bottles, and incubated at room temperature for different ensiling days. Read More
