During colonization of the vaginal tract Candida glabrata cells are challenged with the presence of acetic acid at a low pH, specially when dysbiosis occurs. To avoid exclusion from this niche C. glabrata cells are expected to evolve efficient adaptive responses to cope with this stress; however, these responses remain largely uncharacterized, especially in vaginal strains. In this work a cohor...

Barley yellow dwarf virus (BYDV) is a phloem limited virus that is persistently transmitted by aphids. Due to huge yield losses in agriculture, the virus is of high economic relevance. Since the control of the virus itself is not possible, tolerant barley genotypes are considered as the most effective approach to avoid yield losses. Although several genes and quantitative trait loci are known a...

The effect of the herbicides and aryloxy-phenoxy-propionic acid derivatives diclofop, fenoxaprop, fluazifop and haloxyfop and their ethyl, methyl or butyl esters on the de novo fatty-acid biosynthesis of isolated chloroplasts was investigated with intact chloroplasts isolated from sensitive grasses (Poaceae) and tolerant dicotyledonous plants (Pisum, Spinacia). The 4 herbicides (free-acid form)...

background and aims: the aim of this study was to determine the correlation between the hepatitis b virus surface ag (hbsag) genotypes and variations in the clinical/serological pictures among hbsag positive chronic patients from south khorasan province of iran. methods: twenty-five patients were enrolled in this study. the hbs ag gene was amplified and was directly sequenced. genotypes and nuc...

conclusions these human-derived lab and bifidobacteria exhibited different mechanisms involved in pathogenic inhibition. therefore a combination of these probiotic strains could be a great promise and possibility for the development of probiotic products to effectively prevent and control food-borne infection in humans. background food-borne pathogens are among the most significant problems in ...

Abstract Screening of hybrid corn parent lines quickly and cheaply compared to hydroponic methods in the laboratory is needed support assembly new high yielding varieties acid tolerant corn. Addition CaCO 3 as equivalent 2 t/ha (normal soil), while 0.5 AlCl (acidic). A total 12 elite maize were tested based on relative root growth (RRG). Four sets experiments made, namely normal soil media (pH ...

BACKGROUND Acetic acid is a predominant by-product of lignocellulosic biofuel process, which inhibits microbial biocatalysts. Development of bacterial strains that are tolerant to acetic acid is challenging due to poor understanding of the underlying molecular mechanisms. RESULTS In this study, we generated and characterized two acetic acid-tolerant strains of Zymomonas mobilis using N-methyl...
