fermentation 
 
the enzymatic degration of carbohydrates  in which the final acceptor is an organic molecule atp is synthesized by substrate-level phosporylation an O2 us not required
pathogenic
 
disease producing and disease causing organism
hooke , robert 
 
he was the first to discover that living things were composed of cells
he was the first to observe a cell 
van  leewenhoek
 
was the first observe a living microorganism through a magnifying lense of mor than 400 microscope he constructed 
he was the first to observe a living cell
pasteur
 
discovered that microorganisms cannot originate from mysterical forces present in nonlivig materials. rather any appearens of spontaneous life in nonliving solutions can be attributed to microorganisms that were already present in the air or in fluid themselves
koch , robert 
 
he discovered the first proof that bacteria actually causes disease he discovered rod shaped bacteria now known as bacillus anthracis in the blood of cattle that had died of anthrax kock then established koch postulates
