در پژوهش حاضر، سه گونه باکتریایی بیمارگر erwinia carotovora، xanthomonas axonopodis و streptomyces turgidiscabies به منظور یافتن پکتیناز خارج سلولی که توانایی شکست پکتین مرکبات با درجه استریفیه بالا را دارد، مورد بررسی قرار گرفت. در این میان، گونه xanthomonas axonopodis دارای بهترین فعالیت پکتینازی می باشد. بهینه سازی شرایط کشت نشان داد که این باکتری در محیط حاوی1/0% پکتین مرکبات، 1% پپتن، 1%ye...

The role of sialic acid in the gel-filtration behaviour of sialoglycoproteins was investigated by using the separated isoenzymes of purified human liver alpha-L-fucosidase and several other well-known sialic acid-containing glycoproteins (fetuin, alpha1-acid glycoprotein, thyroglobulin and bovine submaxillary mucin). For each glycoprotein studied, gel filtration of its desialylated derivative g...

Gel-filtration chromatography is a versatile method that permits the effective separation of biological molecules in high yield. This article describes the basis of the method, the selection of suitable operating conditions, and contrasts typical matrix types. Applications of the technique are described, with references to the scientific literature.

This study linked the chemical potential change to high specific filtration resistance (SFR) of gel layer, and then proposed a novel membrane fouling mechanism regarding gel layer filtration, namely, Flory-Huggins based filtration mechanism. A mathematical model for this mechanism was theoretically deduced. Agar was used as a model polymer for gel formation. Simulation of the mathematical model...
