Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Germination test of Eucalyptus phaeotricha seeds

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental
The rules for seed analysis do not have recommendations for conducting the germination test of Eucalyptus phaeotricha seeds. Thus, the aim of this study was to determine the best substrate, temperature, conduction time, and substrate moistening level for

Enraizamento de estacas semilenhosas de oliveira sob efeito de diferentes épocas, substratos e concentrações de ácido indolbutírico Rootings of semi-woody cuttings of olive tree under effects of collection time, substrate, and concentrations of indol-3-butiric acid (IBA)

open access: yesCiência e Agrotecnologia, 2003
Com o objetivo de avaliar o enraizamento de estacas semilenhosas de oliveira (Olea europaea L.), sob efeito de diferentes épocas, substratos e concentrações de ácido indolbutírico (AIB), foram conduzidos na Fazenda Experimental da EPAMIG em Maria da Fé ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

A Review of Pretreatment Strategies for Anaerobic Digestion: Unlocking the Biogas Generation Potential of Wastes in Ghana

open access: yesWaste
Anaerobic digestion (AD) is a sustainable method of treating organic waste to generate methane-rich biogas. However, the complex lignocellulosic nature of organic waste in most cases limits its biodegradability and methane potential.

Substrate-Selective Catalysis Enabled Synthesis of Azaphilone Natural Products [PDF]

open access: yes
Achieving substrate-selectivity is a central element of nature’s approach to synthesis. By relying on the ability of a catalyst to discriminate between components in a mixture, control can be exerted over which molecules will move forward in a synthesis.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Symbiotic propagation of seedlings of Cyrtopodium glutiniferum Raddi (Orchidaceae)

open access: yesActa Botânica Brasílica, 2013
In nature, orchid seeds obtain the nutrients necessary for germination by degrading intracellular fungal structures formed after colonization of the embryo by mycorrhizal fungi.

Substrate-Assisted Hydroxylation and O‑Demethylation in the Peroxidase-like Cytochrome P450 Enzyme CYP121 [PDF]

open access: yes, 2019
CYP121 is a P450 enzyme from Mycobacterium tuberculosis that catalyzes a C–C coupling reaction between the two aromatic rings on its native substrate cyclo­(l-Tyr-l-Tyr) (cYY) to form mycocyclosin, a necessary product for cell survival.
