Nyob rau hauv xyoo tas los no, niaj hnub biotechnology sawv cev los ntawm genetic engineering, cell engineering, enzyme engineering thiab fermentation engineering tau tsim sai heev, thiab muaj kev cuam tshuam thiab hloov pauv tib neeg kev tsim khoom thiab kev ua neej. Lub npe hu ua biotechnology hais txog "txoj kev siv cov khoom muaj sia nyob (lossis cov khoom siv roj ntsha) los txhim kho cov khoom, nroj tsuag thiab tsiaj txhu, lossis cog cov kab mob rau lub hom phiaj tshwj xeeb". Bioengineering yog lub ntsiab lus dav dav ntawm biotechnology, uas yog hais txog kev sib xyaw ntawm Biochemistry, molecular biology, microbiology, noob caj noob ces thiab biochemical engineering los hloov lossis rov tsim cov genetic khoom ntawm cov hlwb tsim, cog ntau yam tshiab, siv cov kab mob uas twb muaj lawm ntawm kev lag luam. , thiab tsim cov khoom lag luam los ntawm cov txheej txheem biochemical. Nyob rau hauv luv luv, nws yog cov txheej txheem ntawm industrialization ntawm cov kab mob nyob, lub neej systems los yog lub neej txheej txheem. Bioengineering muaj xws li genetic engineering, cell engineering, enzyme engineering, fermentation engineering, bioelectronic engineering, bioreactor, sterilization technology thiab cov protein engineering.
