    Arch Microbiol 2017 Aug 22. Epub 2017 Aug 22.
    Department of Biotechnology, Haldia Institute of Technology, Haldia, West Bengal, 721657, India.
    Matching the global food demand by 2050 and to ensure the stability of food security in over than 99 countries, it is necessary to scale up the production of food such as sorghum, wheat, rice, maize and sugarcane which are however natural hosts of Cochliobolus species. Cochliobolus species major epidemics such as the Great Bengal famine, Southern corn leaf blight, and Northern leaf spot blight were associated with substantial economic losses in the past decades. Thus, there is an urgent need to establish a specific coordinated global surveillance program for the migration of invasive Cochliobolus species, planning contextual control programs engaging all agricultural stakeholders and information sharing in real time for prevention of disastrous Cochliobolus disease outbreak effects.

    Lipid droplets accumulation and other biochemical changes induced in the fungal pathogen Ustilago maydis under nitrogen-starvation.
    Arch Microbiol 2017 May 26. Epub 2017 May 26.
    Escuela Nacional de Ciencias Biológicas, Instituto Politécnico Nacional, Ciudad De México, Mexico.
    In many organisms, the growth under nitrogen-deprivation or a poor nitrogen source impacts on the carbon flow distribution and causes accumulation of neutral lipids, which are stored as lipid droplets (LDs). Efforts are in progress to find the mechanism of LDs synthesis and degradation, and new organisms capable of accumulating large amounts of lipids for biotechnological applications. In this context, when Ustilago maydis was cultured in the absence of a nitrogen source, there was a large accumulation of lipid bodies containing mainly triacylglycerols. Read More

    Aluminum (Al) is ubiquitous and toxic to microbes. High Al(3+) concentration and low pH are two key factors responsible for Al toxicity, but our present results contradict this idea. Here, an Al-tolerant yeast strain Rhodotorula taiwanensis RS1 was incubated in glucose media containing Al with a continuous pH gradient from pH 3. Read More

    Properties of Streptomyces albus J1074 mutant deficient in tRNA(Leu)UAA gene bldA.

    Streptomyces albus J1074 is one of the most popular and convenient hosts for heterologous expression of gene clusters directing the biosynthesis of various natural metabolic products, such as antibiotics. This fuels interest in elucidation of genetic mechanisms that may limit secondary metabolism in J1074. Here, we report the generation and initial study of J1074 mutant, deficient in gene bldA for tRNA(Leu)UAA, the only tRNA capable of decoding rare leucyl TTA codon in Streptomyces. Read More

    A metabonomic analysis on the response of Enterobacter cloacae from coastal outfall for land-based pollutant under phoxim stress.

    School of Marine Science, Ningbo University, 818 Fenghua Road, Ningbo, Zhejiang, 315211, People's Republic of China.
    Enterobacter cloacae is an opportunistic pathogen widely distributed in human and animal intestinal systems. The secretion of extended-spectrum β-lactamases (ESBLs) and cephalosporinase (AmpC) endows E. cloacae with strong drug resistance. Read More

    The effectiveness of anti-biofilm and anti-virulence properties of dihydrocelastrol and dihydrocelastryl diacetate in fighting against methicillin-resistant Staphylococcus aureus.
    Arch Microbiol 2017 May 9. Epub 2017 May 9.
    Department of Medical Sciences, College of Medical Sciences, Soonchunhyang University, Asan, 31538, Republic of Korea.
    Human pathogens have readily been converted into multidrug-resistant pathogens, such as methicillin-resistant Staphylococcus aureus (MRSA), because of the long-term use of conventional antibiotics. In addition, the biofilms formed by S. aureus cells are especially problematic and are related to the persistence of chronic infections because they constitute a major mechanism of promoting tolerance to diverse antimicrobial agents.

    Identification of the zinc, copper and cadmium metalloproteome of the protozoon Tetrahymena thermophila by systematic bioinformatics.
    Arch Microbiol 2017 May 6. Epub 2017 May 6.
    Department of Chemistry, University of Patras, Rion, 26504, Greece.
    Tetrahymena thermophila (T. thermophila) is a ciliated protozoon that can detect freshwater pollution by heavy metals ("whole-cell biosensor"). This work employed a systematic bioinformatics approach to predict and analyze the metalloproteome of T. Read More

    Erythrobacter alti sp. nov., a marine alphaproteobacterium isolated from seawater.

    College of Pharmacy, Keimyung University, 1095 Dalgubeoldaero, Dalseo-Gu, Daegu, 42601, Republic of Korea.
    A polyphasic taxonomic study was performed on strain KMU-34(T), which was isolated from seawater in the Republic of Korea. The bacterial cells were Gram-stain-negative, strictly aerobic, chemoheterotrophic, yellow-pigmented and rod-shaped. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the novel marine strain was affiliated with the family Erythrobacteraceae of the class Alphaproteobacteria and that it showed highest sequence similarity (98.

    Identification of proteins differentially expressed by Chlamydia trachomatis treated with chlamydiaphage capsid protein VP1 during intracellular growth.
    Arch Microbiol 2017 Apr 25. Epub 2017 Apr 25.
    Department of Dermatovenereology, Tianjin Medical University General Hospital, 154 Anshan Road, 300052, Tianjin, China.
    Chlamydia trachomatis infection is one of the most prevalent sexually transmitted diseases. Our research pertains to the inhibitory effect and molecular mechanism of the chlamydiaphage capsid protein VP1 on the growth of Chlamydia trachomatis. In this research, the capsid protein VP1 of the guinea-pig conjunctivitis chlamydiaphage phiCPG1 was expressed, purified and identified, and then, it was applied to the cultivation of different serovars of Chlamydia trachomatis and Chlamydia psittaci.

    Two distinct periplasmic enzymes are responsible for tellurite/tellurate and selenite reduction by strain ER-Te-48 associated with the deep sea hydrothermal vent tube worms at the Juan de Fuca Ridge black smokers.
    Arch Microbiol 2017 Apr 21. Epub 2017 Apr 21.
    Department of Microbiology, University of Manitoba, Winnipeg, MB, R3T 2N2, Canada.
    Strain ER-Te-48 isolated from a deep-ocean hydrothermal vent tube worm is capable of resisting and reducing extremely high levels of tellurite, tellurate, and selenite, which are used for respiration anaerobically. Tellurite and tellurate reduction is accomplished by a periplasmic enzyme of 215 kDa comprised of 3 subunits (74, 42, and 25 kDa) in a 2:1:1 ratio. The optimum pH and temperature for activity is 8.
