ONLINE ETYMOLOGY DICTIONARY:

microbiology (n.)

1880, coined in English from micro- + biology. Related: Microbiological.

micro-

word-forming element meaning "small, microscopic; magnifying; one millionth," from Latinized comb. form of Gk. mikros "small, little, petty, trivial, slight" (see mica).

biology (n.)

1819, from Gk. bios "life" (see bio-) + -logy. Suggested 1802 by German naturalist Gottfried Reinhold Treviranus (1776-1837), and introduced as a scientific term that year in French by Lamarck.

bio-

word-forming element, from Gk. bio-, comb. form of bios "one's life, course or way of living, lifetime" (as opposed to zoe "animal life, organic life"), from PIE root *gweie- "to live" (cf. Skt. jivah "alive, living;" O.E. cwic "alive;" L. vivus "living, alive," vita "life;" M.Pers. zhiwak "alive;" O.C.S. zivo "to live;" Lith. gyvas "living, alive;" O.Ir. bethu "life," bith "age;" Welsh byd "world"). Equivalent of L. vita. The correct usage is that in biography, but in modern science it has been extended to mean "organic life."

-logy

word-forming element meaning "a speaking, discourse, treatise, doctrine, theory, science," from Gk. -logia (often via Fr. -logie or M.L. -logia), from root of legein "to speak;" thus, "the character or deportment of one who speaks or treats of (a certain subject);" see lecture (n.).
