1. Calcium nwere ike ime ka usoro biofilm guzosie ike ma nọgide na-eguzosi ike n'ezi ihe

Calcium bụ ihe dị mkpa maka osisi na akụkụ dị mkpa nke mgbidi cell.

Ebe biofilm kwụsiri ike nwere ike imeziwanye nguzogide nke ihe ọkụkụ iji retrograde. N'otu oge ahụ, n'ihi na calcium nwere ike ime ka selectivity nke cell akpụkpọ ahụ maka absorption nke potassium, sodium na magnesium ion, na potassium na sodium ion nwere ike na-akwalite nkwụsi ike nke mkpụrụ ndụ, si otú na-eme ka retrograde iguzogide ihe ubi. N'ikwu ya n'ezoghị ọnụ, calcium nwere ike imeziwanye nguzogide retrograde nke ihe ọkụkụ.

2. Nwere ike igbochi ịka nká
