Putative Biosynthesis of Talarodioxadione & Talarooxime from Talaromyces stipitatus

open access: yesMolecules, 2022
Polyesters containing 2,4-dihydroxy-6-(2-hydroxypropyl)benzoate and 3-hydroxybutyrate moieties have been isolated from many fungal species. Talaromyces stipitatus was previously reported to produce a similar polyester, talapolyester G.

Beech wood treated with polyglycerol succinate: a new effective method for its protection and stabilization [PDF]

open access: yes, 2020
This paper deals with an original and non-biocidal chemical treatment consisting of a vacuum/pressure impregnation step of beech wood with a water-borne mixture made from heat-activated condensation of succinic anhydride (SA) and glycerol (G).

Isohexide and sorbitol-derived, enzymatically synthesized renewable polyesters with enhanced Tg [PDF]

open access: yes, 2016
Sugar-based polyesters derived from sorbitol and isohexides were obtained via solvent-free enzymatic catalysis. Pendant hydroxyl groups, coming from the sorbitol units, were present along the polyester backbone, whereas the two isohexides, namely ...

Effect of hydroxyapatite nanoparticles on the degradability of random poly(butylene terephthalate-co-aliphatic dicarboxylate)s having a high content of terephthalic units [PDF]

open access: yes, 2016
Copolyesters derived from 1,4-butanediol and constituted also of aliphatic and aromatic dicarboxylate units in a molar ratio of 3:7 were synthesized by a two-step polycondensation procedure.
