Microbacterium Shaanxiense Sp. Nov., Isolated from the Nodule Surface of Soybean
International Journal of Systematic and Evolutionary Microbiology (2015), 65, 1437–1443 DOI 10.1099/ijs.0.000116 Microbacterium shaanxiense sp. nov., isolated from the nodule surface of soybean Shi Peng, Liu Dongying, Yang Bingxin, Li Mingjun and Wei Gehong Correspondence State Key Laboratory of Soil Erosion and Dryland Farming on the Loess Plateau, College of Life Wei Gehong Sciences, Northwest A&F University, Yangling, Shaanxi 712100, PR China [email protected] A Gram-stain-positive, non-motile, catalase- and oxidase-positive rod, designated CCNWSP60T, was isolated from the nodule surface of soybean [Glycine max (L.) Merrill] cultivar Zhonghuang 13. 16S rRNA gene sequence analysis clearly showed that the isolate belonged to the genus Microbacterium. On the basis of pairwise comparisons of 16S rRNA gene sequences, strain CCNWSP60T was most closely related to Microbacterium murale DSM 22178T (98.8 % similarity), Microbacterium aerolatum DSM 14217T (98.3 %), Microbacterium ginsengiterrae DSM 24823T (98.0 %) and Microbacterium profundi DSM 22239T (97.8 %). However, the DNA– DNA relatedness values of strain CCNWSP60T to M. murale DSM 22178T, M. aerolatum DSM 14217T, M. ginsengiterrae DSM 24823T and M. profundi DSM 22239T were 48 %, 43 %, 28 % and 41 %, respectively. Growth of strain CCNWSP60T occurred at 4–40 6C and at pH 5.0–9.0. The NaCl range for growth was 0–4 % (w/v). The predominant menaquinone of strain CCNWSP60T was MK-13; MK-12 was also detected. The major polar lipids were dipho- sphatidylglycerol, phosphatidylglycerol, one unidentified glycolipid and one unidentified phos- pholipid. The diagnostic diamino acid of the peptidoglycan was ornithine. The acyl type of the peptidoglycan was glycolyl. -
Identification of Fungi and Bacteria Associated with Internally Discolored Horseradish Roots
IDENTIFICATION OF FUNGI AND BACTERIA ASSOCIATED WITH INTERNALLY DISCOLORED HORSERADISH ROOTS BY JUNMYOUNG YU THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Crop Sciences in the Graduate College of the University of Illinois at Urbana-Champaign, 2010 Urbana, Illinois Adviser: Professor Mohammad Babadoost ABSTRACT This study was conducted to identify fungi and bacteria associated with the internally discolored horseradish roots. During 2008-2009, 75, 306, 115, and 120, horseradish roots from California, Illinois, Ontario (Canada), and Wisconsin, respectively, were collected and tested for the presence of fungi and bacteria. The roots were surface- disinfected and five segments (5 mm thick) were cut from each root and placed onto acidified potato dextrose agar (A-PDA) and nutrient agar (NA) in Petri plates. The plates were incubated at 22-24 C with 12 h light/12 h darkness. Morphological characteristics of fungal isolates were examined and compared with the references. Molecular identification of the fungal isolates was accomplished by sequence analysis of the PCR products, using fungal universal primers (ITS5 and ITS4) for all fungal isolates, mitochondrial DNA primers cox3A-cox3B and nad1A-nad1B for Verticillium isolates, and elongation factor 1 alpha primer EF-1H-EF-2T and mitochondrial small subunit rDNA primers NMS1-NMS2 for Fusarium isolates. A total of 18 fungal genera were identified, which included Alternaria (3.8% roots), Arthopyreniaceae (0.4%), Chaetomium (0.6%), Colletotrichum (2.3%), Cordyceps (2.3%), Cylindrocarpon (0.9%), Fusarium (31.8%), Neonectria (1.3%), Penicillium (4.4%), Phoma (0.1%), Phomopsis (0.4%), Pyrenochaeta (2.7%), Rhizoctonia (0.1%), Rhizopus (1.0%), Rhizopycnis (0.4), Trichurus (0.6%), Ulocladium (0.4%), and Verticillium (38.0%). -

Microbial Environment Affects Innate Immunity in Two Closely Related Earthworm Species Eisenia Andrei and Eisenia Fetida
Microbial Environment Affects Innate Immunity in Two Closely Related Earthworm Species Eisenia andrei and Eisenia fetida Jiří Dvořák1, Veronika Mančíková1, Václav Pižl2, Dana Elhottová2, Marcela Šilerová1, Radka Roubalová1, František Škanta1, Petra Procházková1, Martin Bilej1* 1 Laboratory of Cellular and Molecular Immunology, Institute of Microbiology of the Academy of Sciences of the Czech Republic, v. v. i., Prague, Czech Republic, 2 Department of Soil Zoology and Soil Microstructure, Institute of Soil Biology, Biology Center of the Academy of Sciences of the Czech Republic, v. v. i., České Budějovice, Czech Republic Abstract Survival of earthworms in the environment depends on their ability to recognize and eliminate potential pathogens. This work is aimed to compare the innate defense mechanisms of two closely related earthworm species, Eisenia andrei and Eisenia fetida, that inhabit substantially different ecological niches. While E. andrei lives in a compost and manure, E. fetida can be found in the litter layer in forests. Therefore, the influence of environment-specific microbiota on the immune response of both species was followed. Firstly, a reliable method to discern between E. andrei and E. fetida based on species-specific primers for cytochrome c oxidase I (COI) and stringent PCR conditions was developed. Secondly, to analyze the immunological profile in both earthworm species, the activity and expression of lysozyme, pattern recognition protein CCF, and antimicrobial proteins with hemolytic function, fetidin and lysenins, have been assessed. Whereas, CCF and lysozyme showed only slight differences in the expression and activity, fetidin/lysenins expression as well as the hemolytic activity was considerably higher in E. andrei as compared to E. -
