Why did Angelina Hesse suggest using agar?
Angelina, who cooked both the family’s meals and the beef stock that the bacteria ate in her kitchen, suggested that Walther use agar-agar, which is more heat-stable than gelatin and used to make soups, desserts, and jellies, particularly in Asia.
Who was Angelina Fanny Hesse and how did she influence the field of microbiology?
Angelina Fanny Hesse Contributed Agar and Art to Microbiology. Hesse not only contributed agar to microbiology, but she also worked in Koch’s lab as an assistant, much like one of today’s lab technicians, and was a scientific illustrator. Walther used her drawings of his microscopy in his publications.
Who invented the most common bacterial medium?
Beginning in the late 19th century, agar began to be used as a solid medium for growing various microbes. Agar was first described for use in microbiology in 1882 by the German microbiologist Walther Hesse, an assistant working in Robert Koch’s laboratory, on the suggestion of his wife Fanny Hesse.
Who is the mother of microbiology?
Fanny Hesse, acknowledged as the mother of microbiology, whose birthday would have been today, is best known for her work developing agar for cell culture.
Who invented petri dish?
Julius Richard Petri
Petri dish/Inventors
The Petri dish, a circular flat dish with a lid that is used for growing bacteria on a bed of nutrient jelly, is one such innovation. It can be found in any immunology laboratory in the world and its basic design has not changed since it was first invented in 1887 by a German microbiologist called Julius Richard Petri.
Who suggested the use of agar as solidifying agent?
Fannie Eilshemius Hesse, the New Jersey – born wife of Walther Hesse, one of Koch’s assistants, had learned of agar from a Dutch acquaintance and suggested its use when she heard of the difficulties with gelatin. Agar – solidified medium was an instant success and continues to be essential in all areas of microbiology.

What pH do most bacteria grow best in?
6.5 – 7.0
Most bacteria grow best around neutral pH values (6.5 – 7.0), but some thrive in very acid conditions and some can even tolerate a pH as low as 1.0. Such acid loving microbes are called acidophiles.

Who is the father of microorganisms?
Antoni van Leeuwenhoek
Antoni van Leeuwenhoek (1632-1723), a cloth trader from Delft, is the founding father of microbiology. He used home-made microscopes to discover the invisible world of micro-organisms. Antoni van Leeuwenhoek (1632-1723), a cloth trader from Delft, is the founding father of microbiology.
What is agar made of?
Agar is a mixture of two components: the linear polysaccharide agarose and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae and is released on boiling.
