Polyhydroxyalkanoate production from crude glycerol by newly isolated Pandoraea sp. Polyhydroxyalkanoate production from crude glycerol

, 2018
A new bacterial strain was isolated from Atlantic rainforest in Brazil for polyhydroxyalkanoate (PHA) production utilizing crude glycerol from biodiesel industry (CG) and it was identified as Pandoraea sp. MA03. Shake flask experiments were performed at 10–50 g L−1 carbon source and showed the best values of poly(3-hydroxybutyrate) (P3HB) production ...

Isolation and Characterization of Random Citrate Synthase Variants That Increase Acetate Generation by Escherichia coli

Biotechnology and Bioengineering, EarlyView.
ABSTRACT A method to select Escherichia coli citrate synthase variants having reduced activity was developed based initially on the increased generation of acid, observed visually by prolonged color change in the pH indicator bromocresol purple. Five hundred fifty‐two potential variants were isolated and each were cultured on glucose as sole carbon ...

Synergetic hydrothermal co-liquefaction of crude glycerol and aspen wood

, 2015
Crude glycerol-assisted hydrothermal co-liquefaction of aspen wood was studied in batch micro-reactors. An experimental matrix of 14 experiments was defined to investigate the effects of three different process parameters on the yields of biocrude and ...

Structural compatibility between β‐lactams and substrate binding pockets of IMP‐1 and NDM‐1 determines the substrate spectrum

Bulletin of the Korean Chemical Society, EarlyView.
Chemical structures of three β‐lactam classes and the substrate‐binding pockets (SBPs) of B1 metallo‐β‐lactamases (MBLs) were compared. Structural compatibility between β‐lactams and MBL SBPs correlates with enzymatic activity, providing insights into the substrate spectrum of MBLs and β‐lactam resistance.

Monoclonal Antibodies; Detection Tools for Wheat Alpha‐Amylase Proteins

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Expression of alpha‐amylase proteins during germination or other physiological events may lower grain soundness and have a negative impact on end‐use quality. The objective of the current study was to validate two new monoclonal peptide antibodies for wheat alpha‐amylases and describe alpha‐amylase expression in ...

Autocatalytic Acetylation of Crude Glycerol Using Acetic Acid: A Kinetic Model

Reactions
The aim of this work was to develop a kinetic model based on the power law to describe the evolution of glycerol conversion and product distribution in the crude glycerol (G) acetylation reaction with acetic acid (AA) without the use of a catalyst.

Thermophilic co-digestion of poultry litter and crude glycerol

, 2019
Crude glycerol was evaluated as co-substrate in a thermophilic digester that had been stabilized on poultry litter feedstock. The experiment showed that crude glycerol caused stress to the system whereby methane and total biogas production greatly ...
