Article Synopsis
- - Bacterial cellulose (BC) is a promising material for wound healing due to its water retention, flexibility, and biocompatibility, but it lacks antibacterial properties, which limits its use in treating infected wounds.
- - This study developed BC-based dressings enhanced with ε-polylysine and polydopamine, which showed strong antibacterial effects and promoted better wound healing in tests with rats compared to regular BC dressings.
- - Results showed that the modified membranes not only improved healing outcomes but also resulted in smoother and thicker new skin, highlighting their potential for future clinical applications in managing infected wounds.
The oil/water (o/w) separation is a global challenge because of the increasing water contamination by oil spill accidents, and oil-containing wastewater produced by food, textile, and petrochemical industries. In this study, we have developed bacterial cellulose (BC) based superhydrophilic/underwater superoleophobic (SUS) membrane for o/w separation. The membrane was designed through a facile method by blending BC nanofibers with silica microparticles (SiO-MPs), which was further modified by bio-inspired polydopamine (PDA) coatings.

In this study, cheaper plant cellulose needle-leaf bleached kraft pulp (NBKP) was added to BC to increase the pore size of the composite membrane, and a superhydrophobic/superoleophilic membrane was prepared for oil-/water separation. The modified membrane surface displayed a petal-like micro-structure and a water contact angle (WCA) of 162.

However, BC productivity has been impeded by the lack of efficient genetic engineering techniques. In this study, a lambda Red and FLP/FRT-mediated site-specific recombination system was successfully established in .

First of all, with the framework of SFLA, an improved frog-leap operator is designed with the effect of the global optimal information on the frog leaping and information exchange between frog individuals combined with genetic mutation with a small probability. Subsequently, in order to improve the convergence speed and enhance the exploitation ability, a novel CS model is proposed with considering the specific advantages of Lévy flights and frog-leap operator.

Objective: To develop a quantitative method for determination of the total organic acids and salicyclic acid in the extract of Radix Isatidis.
Method: The total organic acids were determined by acid-base titration and the salicylic acid was determined by HPLC.
Result: It was shown that contents of total organic acids and salicylic acid in the extract of Radix Isatidis were 13.
