I-Hielscher Ultrasound Technology

Ukuchithwa kwe-ultrasonic yezinhlaka zeselula

I-ultrasonication iyindlela ephumelelayo yokuphula izakhiwo zeseli. Lo mphumela ungasetshenziselwa ukukhishwa kwezinto zokwenziwa kwe-intracellular, isib. Isitashi kusuka ematrix esitokisini.

I-Ultrasonication ikhiqiza ukushintshwa kwamagagasi aphezulu nokucindezela okuphansi ngaphansi ketshezi ebonakalayo. Ngesikhathi umjikelezo ophansi ocindezelayo, amagagasi e-ultrasonic enza ama-bubbles amancane okugcoba emanzini awela phansi ngokuhlukumeza ngesikhathi somjikelezo ophezulu wokucindezela. Lesi simo sibizwa cavitation. I-implosion ye-cavitation bubble ibangele amabutho anamandla ase-hydrodynamic shear.

Amandla we-shear angakwazi ukuhlukanisa izinto ezinamathebhu, izinto zokwabelana nge-cellulosic zibe izinhlayiya ezinhle futhi aphule izindonga zesakhiwo seseli. Lokhu ikhishwa okungaphezulu kwezinto zangaphakathi neselula, njenge-isitashi noma ushukela endaweni engetshezi. Ngaphezu kwalokho lokho okubonakalayo kwendonga yeselula kuphulwa zibe izidumbu ezincane.

Lo mphumela ungasetshenziselwa Ukuvuthwa, ukugaya kanye nezinye izinqubo zokuguqulwa zendaba eziphilayo. Ngemuva kokugaya nokugaya, i-ultrasonication yenza okungaphezulu kwezinto zangaphakathi-isib. Isitashi kanye nama-debris odongeni lweseli iyatholakala kuma-enzyme okuguqula isitashi zibe ushukela. Iyakwenza futhi ukwandisa indawo evezwe ezinzymeni ngesikhathi sokuphuza noma ukuhlanjululwa. Lokhu kwenzeka ngokujwayelekile ukwandisa ijubane nokukhiqiza imvubelo yokuvutshelwa nezinye izinqubo zokuguqulwa, isib ukwandisa ukukhiqizwa kwe-ethanol kusuka ku-biomass.

Ukungena kwe-ultrasonic kungahlolwa kalula noma yiliphi isilinganiso:

Sicela usebenzise ifomu elingezansi, uma ungathanda ukuthola ulwazi oluthe xaxa mayelana nokusetshenziswa kwamadivaysi e-ultrasonic ngenhloso yokwehlukaniswa kwamaseli. Sizojabula ukukusiza.

Cela ulwazi oluthe xaxa!









Sicela uqaphele wethu Inqubomgomo yobumfihlo.
