摘要: 采用胰酶水解酪蛋白、LH35乳清蛋白和LH80乳清蛋白分别制得酪蛋白水解物(CH)、LH35乳清蛋白水解物(LH35)和LH80乳清蛋白水解物(LH80)。以Hyclone水解乳蛋白(HLH)为对照,研究了不同水解乳蛋白对BHK-21悬浮细胞生长代谢的影响,结果表明:在培养基中添加2 ag/L水解乳蛋白时,CH、LH35、LH80和HLH对BHK-21悬浮细胞均有促生长作用,其中LH35、LH80促生长效果优于HLH,CH与HLH促生长效果基本一致。水解乳蛋白对BHK-21悬浮细胞的生化、酶和氨基酸的代谢均有不同程度的影响。这为蛋白水解物在细胞培养中的应用奠定基础。

Abstract: Casein hydrolysate (CH),LH35 whey protein hydrolysate (LH35) and LH80 whey protein hydrolysate (LH80) were prepared by trypsin hydrolysis of casein,LH35 whey protein and LH80 whey protein,respectively.Hyclone hydrolyzed milk protein (HLH) was used as a control to study the effects of different hydrolyzed milk proteins on the growth and metabolism of BHK-21 suspension cells.The results showed that when 2g/L hydrolyzed milk protein was added to the medium,CH,LH35,LH80 and HLH had a growth-promoting effect on BHK-21 suspension cells,among which LH35 and LH80 had better growth promoting effects than HLH,and CH and HLH had similar growth promoting effects.Hydrolyzed milk proteins have different effects on the biochemical,enzymatic and amino acid metabolism of BHK-21 suspension cells.This lays the foundation for the application of protein hydrolysates in cell culture.  

Key words: hydrolyzed milk protein, BHK-21 suspension cells, biochemical metabolism, amino acid metabolism
