Publication date: Available online 14 February 2019Source: Food ChemistryAuthor(s): Ritumbhara Choukade, Naveen KangoAbstractAn efficient system for biotransformation of sucrose to fructooligosaccharides (FOS) was obtained using Aspergillus tamarii NKRC 1229 mycelial fructosyltransferase (m-FTase). Zymographic analysis confirmed mycelial localization of the FTase (36 U/g) and lyophilized fungal pellets were used for bioconversion. m-FTase had molecular weight ∼75 kDa with optimum activity at pH 7.0 and 20°C. FOS production after parametric optimization (sucrose - 50 % w/v, m-FTase dose - 4.5 % w/v, inoculum age - 4...

AshboltAbstractA column microcosm was conducted by amending crude oil into Dagang Oilfield soil to simulate the bioremediation process. The dynamic change of microbial communities and metabolic genes in vertical depth soil from 0 to 80 cm were characterized to evaluate the petroleum degradation potential of indigenous microorganism. The influence of environmental variables on the microbial responds to petroleum contamination were analyzed. De...

Publication date: 25 April 2019Source: Journal of Industrial and Engineering Chemistry, Volume 72Author(s): Marcelo César Murguía, Laura Marcela Machuca, Maria Emilia FernandezAbstractThree gemini compounds were synthesized and characterized in the search of an alternative eco-friendly wood preservative. Synthesis was carried out from N,N-dimethylamines and 2-O-acetyl-1,3- dichloropropane as linker molecule. All the synthesized molecules were adequately purified and characterized by TLC, GC, FT-IR and NMR. Their tensioactive properties were determined. All three efficiently lowered the surface tension in aque...

Plascencia-Jatomea M Abstract A wide variety of chitosan (CS) biomaterials have been loaded with different antimicrobial agents to improve the activity of CS against phytopathogenic fungi. Recently, the antimicrobial activity of 1H-pyrrole-2-carboxylic acid (PCA) has been reported as a secondary metabolite of Streptomyces griseus, which was identified as the main bioactive compound in the biological control. However, it is sensitive to light and its activity against filamentous fungi has not yet been reported. The aim of the present research work was to evaluate the biological activity of CS-PCA biocomposites for...

Publication date: Available online 10 February 2019Source: Food ChemistryAuthor(s): Xin Gao, Jing Wu, Dan WuAbstractThe β-galactosidase from Aspergillus oryzae produces galactooligosaccharides with beneficial prebiotic effects through the transglycosylation of lactose. However, its low galactooligosaccharide yield greatly limits its use in industrial applications. Rational design and site-directed mutagenesis were used to produce three mutants of A. oryzae β-galactosidase: N140C, W806F, and N140C/W806F. The galactooligosaccharide yields of N140C (50.7%), W806F (49.3%), and N140C/W806F (59.8%) represent substantia...

Contributors : Sanjoy Paul ; Mark Stamnes ; Scott Moye-RowleySeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Aspergillus fumigatus Af293To determine the genomic binding sites for the Aspergillus fumigatus transcription factor AtrR, we utilized three different strains. One was the wild-type AfS35 which contains a wild-type copy of atrR but lacks any HA tag. The other two are both derived from AfS35 but contain a 3X HA tag replacing the stop codon of atrR. These strains are SPF89 and SPF112, respectively. SPF89 uses the wild-type atrR promoter to drive expression of the epitope-tagged...
