Construction of recombinant lactococcus lactis expressing porcine transmissible gastroenteritis spike glycoprotein and analysis of immunogenicity 基因的重組乳酸乳球菌的構(gòu)建及免疫原性分析
Sds - page analysis revealed that lactococcus lactis nz9800 harbouring pmg36e / nisa restored little ability of nisin production 以lactococcuslactisnz9800為受體菌,研究了表達載體的表達情況。
Using a mouse model , the uk team has also found that a modified bacterium lactococcus lactis can be used to vaccinate against harmful infections 利用小鼠模型,該英國研究小組已經(jīng)發(fā)現(xiàn)了一種基因修飾細菌(乳酸乳球菌)可用于對有害傳染病的免疫接種。
4 . the recombinant plasmid pmg36e / nisa was introduced into lactococcus lactis nz9800 . sds - page analysis revealed that lactococcus lactis nz9800 harbouring pmg36e / nisa restored no ability of nisin production 抽提ecolijm109中的重組質(zhì)粒,轉(zhuǎn)化l . lactisnz9800 ,在含紅霉素的gm17平板上篩選轉(zhuǎn)化子。
This has resulted in the availability of genetically modified l . lactis with prospects for application in food industry . in this studay , genomic dna extracted from lactococcus lactis nizo r5 was used directly as the template for pcr in this paper 乳酸乳球菌是一類長期應用于食品發(fā)酵業(yè)的有益微生物,以乳酸菌為受體的表達系統(tǒng)具有安全、表達產(chǎn)物便于分離,使用方便等優(yōu)點。
Lactococcus lactis is a Gram-positive bacterium used extensively in the production of buttermilk and cheese, but has recently also become famous as the first genetically modified organism to be used alive for the treatment of human disease. L.
