Optimization of CEST MRI Reporter Protein Design Using Cation-Pi Networks. [PDF]

Chemistry
A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...

A thermostable glucoamylase from Bispora sp. MEY-1 with stability over a broad pH range and significant starch hydrolysis capacity.

PLoS ONE, 2014
BackgroundGlucoamylase is an exo-type enzyme that converts starch completely into glucose from the non-reducing ends. To meet the industrial requirements for starch processing, a glucoamylase with excellent thermostability, raw-starch degradation ability

Synergistic effects of multiple enzymes from industrial Aspergillus niger strain O1 on starch saccharification

Biotechnology for Biofuels, 2021
Background Starch is one of the most important renewable polysaccharides in nature for production of bio-ethanol. The starch saccharification step facilitates the depolymerization of starch to yield glucose for biofuels production. The filamentous fungus

The Optimised Statistical Model for Enzymatic Hydrolysis of Tapioca by Glucoamylase Immobilised on Mesostructured Cellular Foam Silica

Bulletin of Chemical Reaction Engineering & Catalysis, 2019
Enzymatic hydrolysis of starches using free glucoamylase to reducing sugars have difficulties in recovering and recycling of the enzyme, hence immobilisation on inert supports were widely studied.

Bioconversion of Industrial Cassava Solid Waste (Onggok) to Bioethanol Using a Saccharification and Fermentation process

International Journal of Renewable Energy Development, 2022
Cassava solid waste (Onggok) is a by-product of the starch industry containing a lot of fiber, especially cellulose and hemicellulose. It has the potential to be converted to bioethanol.

Subsite structure of Chalara paradoxa glucoamylase and interaction of the glucoamylase with cyclodextrins. [PDF]

Agricultural and Biological Chemistry, 1989
The action of Chalara paradoxa glucoamylase (raw-starch-digesting enzyme) was studied with linear and cyclic maltodextrins. Subsite affinities (Ai) of the amylase were evaluated by the subsite theory. The active site was considered to be made up of seven subsites: = 0.05 kcal/mol,,42= 4.99 kcal/mol, A3 = 1.30 kcal/mol, A4 = 0.77 kcal/mol, A5 =0.33 kcal/

Dynamic, Unconstrained Optimization of Secreted Enzyme Production in Fed-Batch Fermentation Using Reinforcement Learning. [PDF]

Biotechnol Bioeng
ABSTRACT Reinforcement learning (RL) has been used to control a wide range of dynamic processes, especially ones that are too complex to model well or have stochastic environmental perturbations. Fed‐batch fermentations are subject to changes in starting cell growth rates and process variations that can affect cell growth and secreted target production.
