β¦ Synopsis
Of 80 strains of lactic acid bacteria tested, only Lactobacillus casei strains HNK10 and L1-8, Lactobacillus plantarum Lc5 and Lactococcus lactis NN01 produced polygalacturonases (EC 3.2.1.) and/or pectin-esterases (EC 3.1.1.). Crude extracellular extracts of strain L1-8 were able to clarify pectin.

Extracellular polygalacturonase (PG) production was estimated in vitro, using liquid cultures of three species of brown-rot decay fungi (Postia placenta, Gloeophyllum trabeum and Serpula incrassata), by cup-plate assay, assay of reducing sugars, and decrease in viscosity. Although all three experime
## Abstract A pectin and poly(lactic acid) (PLA) composite was compounded by extrusion. A model antimicrobial polypeptide, nisin, was loaded into the composite by diffusion. The incorporation of pectin into PLA resulted in a heterogeneous biphasic structure, as revealed by scanning electronic micro
