Abstract ε-Caprolactone is a monomer of poly(ε-caprolactone) which has been widely used in tissue engineering due to its biodegradability and biocompatibility. To meet the massive demand for this monomer, an efficient whole-cell biocatalytic approach was constructed boost ε-caprolactone production using cyclohexanol as substrate. Combining alcohol dehydrogenase (ADH) with cyclohexanone monooxyg...

Electrospun scaffolds of neat poly-ε-caprolactone (PCL), poly-ε-caprolactone/βcyclodextrin inclusion complex (PCL/β-CD) and poly-ε-caprolactone amino derivative inclusion complex (PCL/β-CD-NH2) were prepared by the electrospinning technique. The obtained mats were analyzed by a theoretical model using the Hartree–Fock method with an STO-3G basis set, and characterized by X-ray diffraction (XRD)...

We study the complexity of locally decoding and locally list-decoding error correcting codes with good parameters. We focus on the circuit depth of the decoding algorithm and obtain new efficient constructions and tight lower bounds. our contributions are as follows: 1. We show general transformations from locally decodable and locally list-decodable codes with high-depth, say NC, decoders, int...

We present several sparsification lower and upper bounds for classic problems in graph theory and logic. For the problems 4-Coloring, (Directed) Hamiltonian Cycle, and (Connected) Dominating Set, we prove that there is no polynomial-time algorithm that reduces any nvertex input to an equivalent instance, of an arbitrary problem, with bitsize O(n2−ε) for ε > 0, unless NP ⊆ coNP/poly and the poly...

In order to expand the properties and applications of aliphatic absorbable polyesters, a new biodegradable block copolymer family, poly(ester amide)-b-poly(ε-caprolactone) (PEA-b-PCL), was synthesized and characterized. These copolymers were synthesized by first preparing l-phenylalanine-based poly(ester amide) macroinitiators (Phe-PEAs) with free amine end groups via a solution polycondensatio...

ε-poly-l-lysine (ε-PL) has been routinely used as a natural and safe preservative for many years in the food industry. However, most existing production methods struggle to achieve low cost high simultaneously. In this work, we present co-culture fermentation strategy enhance ε-PL production. Specifically, screened strain from five different strains that could be co-cultured with Streptomyces a...
