A consortium-GB containing two microorganisms Galactomyces geotrichum MTCC 1360 and Bacillus sp. VUS was able to degrade sulfurcontaining dye Brilliant Blue G, optimally at pH 9 and temperature at 50 8C. The ability of consortium-GB to work at higher temperature and pH ranges will help in using this consortium for removal of the dye from textile effluent. Malt extract, peptone and beef extract ...

The efficient synthesis of gala-, epi-, neo-, and muco-quercitols and some brominated quercitols starting from cyclohexa-1,4-diene is reported. Treatment of the dibromide, obtained by the addition of bromine to cyclohexa-1,4-diene, with m-chloroperbenzoic acid (m-CPBA) yielded the dibromoepoxide, which was successfully converted to the desired dibromodiol by treatment with sulfuric acid. The re...

The activation of caspase-3 mediated neuron death is a common process in neurodegenerative diseases. Efficient activated caspase-3 imaging in brain would be helpful to monitor the potential lesion and intervene promptly. However, the blood-brain barrier (BBB) is the major obstacle that hinders the delivery of diagnostic agents into the brain. Herein, the fluorescence resonance energy transfer (...

Nanochannels of mesoporous silica materials were previously found useful for reducing the tumbling motion of encapsulated biomolecules while leaving the biomolecular structure undisturbed. Here we show that experiments of cw-ESR distance measurement in nano-confinement can benefit immediately from the above mentioned features of sufficiently slow molecular tumbling, enabling more accurate deter...

Abstract This work reports an all-atom molecular dynamics study of the first stages aggregation poly( $$\gamma$$ γ -benzyl-L-glutamate)—PBLG—polymers end-capped with C 60 . PBLG self-assembles in water and shows polymorphism when specific changes structure are made. Three variants compared, which differ for l...

let $r$ be an associative ring with identity and $z^*(r)$ be its set of non-zero zero divisors.  the zero-divisor graph of $r$, denoted by $gamma(r)$, is the graph whose vertices are the non-zero  zero-divisors of  $r$, and two distinct vertices $r$ and $s$ are adjacent if and only if $rs=0$ or $sr=0$.  in this paper, we bring some results about undirected zero-divisor graph of a monoid ring ov...

Nisin is a pentacyclic peptide antibiotic active against Gram-positive bacteria. Its thioether rings are formed by two enzymatic steps: nisin dehydratase (NisB)-mediated dehydration of serines and threonines followed by nisin cyclase (NisC)-catalyzed enantioselective coupling of cysteines to the formed dehydroresidues. Here, we report the in vivo activity of NisC to cyclize a wide array of unre...

The microscopic details of how peptides translocate one at a time through nanopores are crucial determinants for transport through membrane pores and important in developing nano-technologies. To date, the translocation process has been too fast relative to the resolution of the single molecule techniques that sought to detect its milestones. Using pH-tuned single-molecule electrophysiology and...
