Puas Bacillus subtilis puas muaj kev txav chaw?
Cov kab mob qus ntawm Bacillus subtilis paub tias hloov pauv cov khoom siv los ntawm txheej txheem ntawm swarming motility[5, 6]. Swarming hlwb secrete lipopeptide surfactant, hu ua surfactin, kom txo qhov nro thiab motility yog powered los ntawm rotating flagella [5, 7, 8]. … subtilis los kawm zawv zawg motility.
Bacillus subtilis txav li cas?
B. subtilis muaj ob hom kev txav mus los, ua luam dej thiab swarming motility uas yog powered los ntawm rotating flagella (73, 113). … Swarming motility, los ntawm qhov sib txawv, tshwm sim raws li pab pawg ntawm cov hlwb tsiv nyob rau hauv 2-dimensions atop khoom nto (75).
Puas yog Bacillus motile?
