High-level fed-batch fermentative expression of an engineered Staphylococcal protein A based ligand in E. coli: purification and characterization [PDF]

open access: yes, 2015
The major platform for high level recombinant protein production is based on genetically modified microorganisms like Escherichia coli (E. coli) due to its short dividing time, ability to use inexpensive substrates and additionally, its genetics is ...

Red wine as resveratrol protective system -

open access: yesCzech Journal of Food Sciences, 2004
The study describes an isomerization of trans-resveratrol exposed to diffused daylight in dependence on temperature and character of liquid sample (type of solvent, wine …). These effects were investigated using the reverse-phase-HPLC method.

Electro-extractive fermentation for efficient biohydrogen production [PDF]

open access: yes, 2011
Electrodialysis, an electrochemical membrane technique, was found to prolong and enhance the production of biohydrogen and purified organic acids via the anaerobic fermentation of glucose by Escherichia coli. Through the design of a model electrodialysis

Homogenization of cocoa beans fermentation to upgrade quality using an original improved fermenter [PDF]

open access: yes, 2017
Cocoa beans (Theobroma cocoa L.) are the main components for chocolate manufacturing. The beans must be correctly fermented at first. Traditional process to perform the first fermentation (lactic fermentation) often consists in confining cacao beans ...

Optimization of whole-cell biotransformation for scale-up production of α-arbutin from hydroquinone by the use of recombinant Escherichia coli

open access: yesAMB Express, 2019
α-Arbutin is an effective skin-whitening cosmetic ingredient and hyperpigmentation therapy agent. It can be synthesized by one-step enzymatic glycosylation of hydroquinone (HQ), but limited by the low yield.

A Precision Microbiome Approach Using Sucrose for Selective Augmentation of Staphylococcus epidermidis Fermentation against Propionibacterium acnes. [PDF]

open access: yes, 2016
Acne dysbiosis happens when there is a microbial imbalance of the over-growth of Propionibacterium acnes (P. acnes) in the acne microbiome. In our previous study, we demonstrated that Staphylococcus epidermidis (S. epidermidis, a probiotic skin bacterium)

Efficient gene editing in Corynebacterium glutamicum using the CRISPR/Cas9 system

open access: yesMicrobial Cell Factories, 2017
Background Corynebacterium glutamicum (C. glutamicum) has traditionally been used as a microbial cell factory for the industrial production of many amino acids and other industrially important commodities. C. glutamicum has recently been established as a

Biohydrogen production from food waste: Influence of the inoculum-to-substrate ratio [PDF]

open access: yes, 2018
In this study, the influence of the inoculum-to-substrate ratio (ISR) on dark fermentative hydrogen production from food waste (FW) was evaluated. ISR values ranging from 0.05 to 0.25 g VSinoculum/g VSsubstrate were investigated by performing batch tests
