© 2022 Elsevier B.V.The aim of this study was to develop hydrogel wound dressings made of photocrosslinkable pectin and gelatin with pH dependent release of curcumin, an antimicrobial agent. Methacrylated forms of pectin and gelatin (PeMA and GelMA, respectively) were synthesized, and hydrogels were prepared with different compositions (1:1, 1:2 and 1:3 v/v ratios of PeMA and GelMA) by UV exposure. Pure GelMA was used as control group. Average pore diameter of hydrogels with the highest PeMA content (P1:G1)...
pH-responsive layer-by-layer films of zwitterionic block copolymer micelles

We report a strategy to incorporate micelles of poly[3-dimethyl (methacryloyloxyethyl) ammonium propane sulfonate]-block-poly[2-(diisopropylamino) ethyl methacrylate] (beta PDMA-b-PDPA) into electrostatic layer-by-layer (LbL) films. We obtained micelles with pH-responsive PDPA-cores and zwitterionic bPDMA-coronae at pH 8.5 through pH-induced self-assembly of bPDMA-b-PDPA in aqueous solution. To incorporate bPDMA-b-PDPA micelles into LbL films, we first obtained a net electrical charge on bPDMA-coronae. Nega...
PH influences intracellular reaction network of beta-lactamase producing Bacillus licheniformis
Çalık, Pınar (Elsevier BV, 2007-09-01)
Effects of pH on metabolic flux distributions in P-lactamase producing Bacillus licheniformis were investigated using metabolic flux analysis, at pH(C) = 6.5, 7.0 and 7.5 controlled-pH conditions. The bioprocess was divided into three periods: Period I (0 < t < 6 h) is the growth phase where beta-lactamase synthesis starts; Period II (6 < t < 8 h) is the transition phase; Period III (8 < t < 12 h) is the stationary phase for the cell-growth where beta-lactamase synthesis increases. The central pathways were...

This thesis study reports on preparation of layer-by-layer (LbL)-modified microparticles based on temperature responsive poly(2-isopropyl-2-oxazoline) (PIPOX) and pH-responsive Tannic Acid (TA), displaying dual responsive multiple drug release. PIPOX, exhibiting lower critical solution temperature (LCST)-type phase behavior, was synthesized through cationic ring opening polymerization (CROP). PIPOX was then partially hydrolyzed in concentrated acid medium, resulting in poly(2-isopropyl-2-oxazoline-r-polyeth...
