Bioinspired Cationic Antimicrobial Polymers

Angewandte Chemie International Edition, Accepted Article.
Antibiotics are an essential tool of modern medicine, which is critically endangered by the spread of antimicrobial resistance (AMR). Without effective antibiotics, a number of medical advancements from the last century are in jeopardy, threatening our global public health and leading to a high death toll.

Plant cell wall degrading enzymes, pectinase and cellulase, in the digestive system of the red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae)

Plant Protection Science, 2014
In digestion, the red palm weevil, Rhynchophorus ferrugineus, has been adapted to overcome the plant cell wall barrier, specially lignocellulosic and pectic compounds, by producing cellulase and pectinase enzymes. Partial biochemical characterisations of

Development of a consolidated bioprocess for the production of citric acid using Aspergillus niger as biocatalyst

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The industrial production of citric acid, an ingredient in beverages, pharmaceuticals, and cosmetics, is based on microbial fermentation of glucose or sucrose. Given the elevated cost of these sugars, lignocellulosic biomass is emerging as a cost‐effective and environmentally friendly feedstock for sustainable bioprocesses.

Screening fungi isolated from historic Discovery Hut on Ross Island, Antarctica for cellulose degradation [PDF]

, 2008
To survive in Antarctica, early explorers of Antarctica's Heroic Age erected wooden buildings and brought in large quantities of supplies. The introduction of wood and other organic materials may have provided new nutrient sources for fungi that were ...

Immobilized cellulase: Interactions between cellulase and nanostructured supports

BIO Web of Conferences, 2023
In this review, we will analyze the main aspects of immobilization of cellulase - an enzyme for processing cellulosic biomass waste - on nanostructured supports. Such substrates provide a large surface area, increased enzymatic load and a favorable environment for increasing the efficiency of cellulase and its stability, which leads to the creation of ...

Bioethanol production from fruit waste using a microbial co‐culture of Bacillus siamensis F2 and Candida albicans GP1

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study explores the sustainable valorization of fruit waste (FW) for bioethanol production using a consolidated bioprocess (CBP) that combines fermentation and enzymatic hydrolysis in a single step. A co‐culture of Bacillus siamensis F2 (a multienzyme producer) and Candida albicans GP1 (a fermentative yeast) was employed to maximize ...

Loop optimization of Trichoderma reesei endoglucanases for balancing the activity–stability trade‐off through cross‐strategy between machine learning and the B‐factor analysis

GCB Bioenergy, Volume 15, Issue 2, Page 128-142, February 2023., 2023
A cross‐strategy combination of machine learning and B‐factor analysis was used to predict beneficial amino acid substitution in endoglucanase (EG) loop optimization. Experimental validation showed single‐site mutated EG concomitantly improved enzymatic activity and thermal properties by 17.21%–18.06% and 49.85%–62.90%, respectively, compared with wild‐

Isolation of Cellulolytic Bacteria and Characterization of the Enzyme

Makara Seri Sains, 2009
Four of cellulolitic bacteria isolates had beencharacterized. The determination of cellulase activity was conducted at the highest production time, using crudeenzymes with the modification of Miller methods (1959) on pure cellulose substrates such as CMC
