Avaliação da composição do meio de cultivo na produção da proteína recombinante PaOLP de Physalis angulata em Escherichia coli recombinante.

Abstract

Currentlywith advances inbiotechnology, in itsdifferent areas such aspharmaceuticals, food, cosmetics, agriculture, the development of newrecombinant proteinshas been an areaofgreat advances inlarge-scale productionfor differentpurposes. Because of their importance recentlyPR- 5 gene was isolatedand designated PaOLP, encodes a novel antifungal protein thatcancould be used inagriculturalbiotechnologystrategiesand/ ordosagein order to controlfungal diseases. In this context, the present work aimed to evaluatethe influenceof the compositionofthe culture medium in order to optimizethe productionofrecombinant PaOLPofPhysalisangulatausing Escherichia coliM15as a host. Thegrowth protein PR-5 andexpression ofrecombinantprotein wasevaluated bydry weightmethodandby parametersfor thespreadsheetZajic.
