FOOD MICROBIOLOGY - LESSON 1

Food microbiology

the study of the specific microorganisms in food (food microbes), and their beneficial and harmful effects on the quality and safety of raw and processed food

Food microbiologists

provide us with knowledge and tools to understand the nature and characteristics of food microbes

Food microbes

it can be beneficial, neutral, or harmful to humans

Francesco Redi

He gained fame for his controlled experiments. One set of experiments refuted the popular notion of spontaneous generation—a belief that living organisms could arise from nonliving matter.

Francesco Redi

He has been called the "father of modern parasitology" and the "founder of experimental biology".

Anton van Leeuwenhoek

universally acknowledged as the father of microbiology

Anton van Leeuwenhoek

He discovered both protists and bacteria More than being the first to see this unimagined world of 'animalcules', he was the first even to think of looking— certainly, the first with the power to see.

John Needham

A microscopist, was a loyal supporter of the aforementioned theory of spontaneous generation, which was the idea that living organisms can develop from non-living matter.

John Needham

His most important experiment claimed that microorganisms in broth developed independently of other cells.

Lazzaro Spallanzani

He found that boiling broth would sterilize it and kill any microorganisms in it.

Lazzaro Spallanzani

He also found that new microorganisms could settle only in a broth if the broth was exposed to the air.

Theodor Schwann

He made numerous contributions to science that include discovery of the enzyme pepsin, spontaneous generation, and identifying the role of microbes in fermentation.

Theodor Schwann

He is most famous for his role in the development of cell theory.

Louis Pasteur

He pioneered the study of molecular asymmetry and discovered that microorganisms cause fermentation and disease

Louis Pasteur

He originated the process of pasteurization and saved the beer, wine, and silk industries in France

Louis Pasteur

He developed vaccines against anthrax and rabies.

Joseph Lister

He found a way to prevent infection in wounds during and after surgery.

Joseph Lister

He was the first to apply the science of Germ Theory to surgery.

Antisepsis System

Lister's ______________ is the basis of modern infection control.

Joseph Lister

His principles made surgery safe and continue to save countless lives.
