Severe plastics pollution derived from the wide use and the past incorrect dispersion of petroleum-based plastics. The development of bioplastics/biopolymers with the same chemical/physical characteristics of conventional plastics can be a solution to ...

Identifying Energy Extraction Optimisation Strategies of Actinobacillus succinogenes [PDF]
A. succinogenes is well known for utilising various catabolic pathways. A multitude of batch fermentation studies confirm flux shifts in the catabolism as time proceeds. It has also been shown that continuous cultures exhibit flux variation as a function of dilution rate.

Development of a markerless knockout method for Actinobacillus succinogenes. [PDF]
ABSTRACT Actinobacillus succinogenes is one of the best natural succinate-producing organisms, but it still needs engineering to further increase succinate yield and productivity. In this study, we developed a markerless knockout method for A.

The Generation of Successive Unmarked Mutations and Chromosomal Insertion of Heterologous Genes in Actinobacillus pleuropneumoniae Using Natural Transformation [PDF]
We have developed a simple method of generating scarless, unmarked mutations in Actinobacillus pleuropneumoniae by exploiting the ability of this bacterium to undergo natural transformation, and with no need to introduce plasmids encoding recombinases or

Succinic acid (SA) is one of the top candidate value-added chemicals that can be produced from biomass via microbial fermentation. A considerable number of cell factories have been proposed in the past two decades as native as well as non-native SA ...

Continuous succinic acid fermentation by Actinobacillus succinogenes [PDF]
Abstract Fermentations were performed in an external recycle bioreactor using CO2 and d -glucose at feed concentrations of 20 and 40 g L−1. Severe biofilm formation prevented kinetic analysis of suspended cell (‘chemostat’) fermentation, while perlite packing enhanced the volumetric productivity by increasing the amount of immobilised cells.

Continuous succinic acid production from xylose by Actinobacillus succinogenes [PDF]
Continuous, anaerobic fermentations of D-xylose were performed by Actinobacillus succinogenes 130Z in a custom, biofilm reactor at dilution rates of 0.05, 0.10 and 0.30 h(-1). Succinic acid yields on xylose (0.55-0.68 g g(-1)), titres (10.9-29.4 g L(-1)) and productivities (1.5-3.4 g L(-1) h(-1)) were lower than those of a previous study on glucose ...

Metabolic Engineering of Actinobacillus succinogenes Provides Insights into Succinic Acid Biosynthesis. [PDF]
ABSTRACT Actinobacillus succinogenes , a Gram-negative facultative anaerobe, exhibits the native capacity to convert pentose and hexose sugars to succinic acid (SA) with high yield as a tricarboxylic acid (TCA) cycle intermediate. In addition, A. succinogenes is capnophilic, incorporating CO

Continuous succinic acid production by Actinobacillus succinogenes on xylose-enriched hydrolysate. [PDF]
Bio-manufacturing of high-value chemicals in parallel to renewable biofuels has the potential to dramatically improve the overall economic landscape of integrated lignocellulosic biorefineries. However, this will require the generation of carbohydrate streams from lignocellulose in a form suitable for efficient microbial conversion and downstream ...
