Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Andisols [PDF]

open access: yes, 2012
Andisols are soils that typically form in loose volcanic ejecta (tephra) such as volcanic ash, cinders, or pumice. They are characterized by andic properties that include physical, chemical, and mineralogical properties that are fundamentally different ...

The impact of native trees, Cordia africana and Ficus sur, and the economically valuable Manihot esculenta on soil chemical properties in an agroforestry system

open access: yesTrees, Forests and People
Native trees in agroforestry systems sustain soil properties by building up and recycling nutrients in a sustainable manner. This manuscript aimed to assess the impact of different agroforestry species on soil chemical properties.

EFFECT OF IRRIGATION WITH THREE DIFFERENT WATER RESOURCES ON SOIL CHEMICAL PROPERTIES OF KAFR-SAQR, El-SHARKIA, EGYPT [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2017
Three irrigation water resources were chosen at Kafr-Saqr district, El-Sharkia Governorate to assess their qualities and their impact on soil properties.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

open access: yesFEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Evaluating of Relationship between Lead Accumulation with Physico-Chemical Properties of Soils of Aqqala, Golestan Province [PDF]

open access: yesمدیریت بیابان, 2019
Lead accumulation in soil is influenced by various factors such as physico-chemical properties of soil, parent materials of rock, soil pollutant resources, organic and chemical fertilizers in agriculture and etc.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Influence of mouldboard ploughing and shallow tillage on soil physical properties and crop performance [PDF]

open access: yes, 2012
This study was conducted in spring 2011 in a long-term field experiment with the objective of assessing the effect of shallow tillage and mouldboard ploughing on some soil physical properties and crop performance.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

The effects of afforestation on soil bacterial communities in temperate grassland are modulated by soil chemical properties [PDF]

open access: yesPeerJ, 2019
Grassland afforestation dramatically affects the abiotic, biotic, and ecological function properties of the original ecosystems. Interference from afforestation might disrupt the stasis of soil physicochemical properties and the dynamic balance of ...
