Effect of Fe-Mo promoters on HZSM-5 zeolitecatalyst for 1-hexene aromatization
(Elsevier B.V., 2018-11-15)
The promotional effect of Fe-Mo species introduced into HZSM-5 (Zeolyst Int.,SiO2/Al2O3 30) zeolite catalyst by the wetness impregnation method for the 1-hexene aromatiza-tion was investigated. The structure and catalytic ...
Cloning, expression and characterization of thermostable YdaP from Bacillus licheniformis 9A
(Acta Biochimica Polonica, 2017)
The Bacillus licheniformis ydaP gene encodes for a pyruvate
oxidase that catalyses the oxidative decarboxylation
of pyruvate to acetate and CO2. The YdaP form of
this enzyme was purified about 48.6-folds to homogeneity
in ...
Sputtered Si and Mg doped hydroxyapatite for biomedical applications
(IOP Publishing, 2018-01-30)
Hydroxyapatite (HAP) coatings are applied on metallic implant materials to combine mechanical
properties of metallic material with bioactivity abilities of HAP ceramic. In this study, HAP coatings
with additions of Si ...
Novel phages of healthy skin metaviromes from South Africa
(Nature Publishing Group, 2018)
Recent skin metagenomic studies have investigated the harbored viral diversity and its possible
influence on healthy skin microbial populations, and tried to establish global patterns of skin-phage
evolution. However, ...
Structure and functional characterization of pyruvate decarboxylase from Gluconacetobacter diazotrophicus
(BioMed Central, 2014)
BACKGROUND: Bacterial pyruvate decarboxylases (PDC) are rare. Their role in ethanol production and in bacterially
mediated ethanologenic processes has, however, ensured a continued and growing interest. PDCs from ...
Virome assembly and annotation: A surprise in the Namib Desert
(Frontiers Research Foundation, 2017)
Sequencing, assembly, and annotation of environmental virome samples is challenging. Methodological biases and differences in species abundance result in fragmentary read coverage; sequence reconstruction is further ...
High-level diversity of tailed phages, eukaryote-associated viruses, and virophage-like elements in the metaviromes of Antarctic soils
(American Society for Microbiology, 2014)
The metaviromes of two distinct Antarctic hyperarid desert soil communities have been characterized. Hypolithic communities,
cyanobacterium-dominated assemblages situated on the ventral surfaces of quartz pebbles embedded ...
Selection of Clostridium spp. in biological sand filters neutralizing synthetic acid mine drainage
(Wiley, 2013)
In this study, three biological sand filter (BSF) were contaminated with a synthetic iron- [1500 mg L-1 Fe(II), 500 mg L-1 Fe(III)] and sulphate-rich (6000 mg L-1 SO2/4-) acid mine drainage (AMD) (pH = 2), for 24 days, to ...
Efficient molecular cloning of environmental DNA from geothermal sediments
(Kluwer Academic Publishers, 2002)
An efficient and simple method for constructing an environmental library using mechanically sheared DNA obtained
directly from geothermal sediments is presented. The method is based on blunt-end modification of DNA
fragments ...
Dissemination and survival of non-indigenous bacterial genomes in pristine Antarctic environments.
(Springer Verlag, 2005)
Continental Antarctic is perceived as a largely pristine environment, although certain localized regions (e.g., parts of the Ross Dependency Dry Valleys) are relatively heavy impacted by human activities. The procedures ...
