Explanation / Answer
9- Ferdinand Cohn, 1850, ferdinand cohn's foremost studies tool inside the 1850s. in the 1850s he studied the increase and division of plant cells. in 1855 he produced papers on the sexuality of sphaeroplea annulina and later volvox globator. within the 1860s he studied plant body structure in numerous specific components. from 1870 onward he generally studied bacteria. he set up using sterile subculture mediums and rediscovered the botanical garden of Lorenz Scholz von Rosenau in Breslau.
10- John Tyndall, (1877) Final blow to SG theory. Demonstrated that dust carries microorganisms. If dust is absent, nutrient broth remains sterile, even if directly exposed to air, provided evidence for existence of exceptionally heat resistant forms of bacteria.
11- Louis Joblot
= did hay infusion experiment
= boiled hay & water & put in jar; no microbes
= unboiled hay & water in jar; got microbes
= inadvertently did sterilization procedure
Discover steralization process for microbial cultureing.
12- Heinrich G. F. Schröder,- (1853) did sterilized hay infusion experiment in a flask
- filtered the air in it through cotton, which prevented organisms from appearing which help in media protecting experiment in microbilogy for bacterial growth production.
