Which of the following is the LEAST effective technique used to sterilize? a) heat b) cold c) ethylene oxide d) filtration
option B. Filteration is the fastest manner to sterilize answers with out heating. This technique includes filtering with a pore length this is too small for microbes to byskip through. Generally filters with a pore diameter of 0.2 um are used for the elimination of bacteria. Membrane filters are greater normally used filters over sintered or seitz or candle filters. It can be referred to that viruses and phage are plenty smaller than bacteria, so the filtration approach isn't always relevant if those are the top concern.
