Secretion of Acetylxylan Esterase From Enables Utilization of Lignocellulosic Biomass as a Carbon Source.

Microalgae offer a promising biological platform for sustainable biomanufacturing of a wide range of chemicals, pharmaceuticals, and fuels. The model microalga is thus far the most versatile algal chassis for bioengineering and can grow using atmospheric CO and organic carbons (e.g.

High-yield secretion of recombinant proteins from the microalga Chlamydomonas reinhardtii.

Microalga-based biomanufacturing of recombinant proteins is attracting growing attention due to its advantages in safety, metabolic diversity, scalability and sustainability. Secretion of recombinant proteins can accelerate the use of microalgal platforms by allowing post-translational modifications and easy recovery of products from the culture media. However, currently, the yields of secreted recombinant proteins are low, which hampers the commercial application of this strategy.

An easy and efficient permeabilization protocol for in vivo enzyme activity assays in cyanobacteria.

Background: Cyanobacteria are photosynthetic bacteria that thrive in diverse ecosystems and play major roles in the global carbon cycle. The abilities of cyanobacteria to fix atmospheric CO and to allocate the fixed carbons to chemicals and biofuels have attracted growing attentions as sustainable microbial cell factories. Better understanding of the activities of enzymes involved in the central carbon metabolism would lead to increasing product yields.

[Endovascular treatment of non-galenic pial arteriovenous fistulas].

Introduction And Objectives: Pial arteriovenous fistulas are infrequent vascular malformations. They are generally congenital and their natural history is ominous. The objective of this work is to describe our experience in their endovascular management and to review the existing literature.

Isolation of cDNA from Jacaratia mexicana encoding a mexicain-like cysteine protease gene.

Cysteine proteases (CPs) from the C1 family, which are similar to papain, can be found in animals and plants, as well as some viruses and prokaryotes. These enzymes have diverse physiological functions and are thus very attractive for science and industry. Jacaratia mexicana, a member of the Caricaceae plant family, contains several CPs, the principal being mexicain, found to favorably compete against papain for many industrial applications due to its high stability and specific activity.
