Why do we need to preserve bacteria?
Answers
Answer:
The goal of preserving the cultures is to slow that death rate so that when the culture is revisited, some of the cells are still viable and available for culturing. The reasons the cells die can be numerous
Answer:
Close observation of preserved specimens can result in an understanding of form and function of bodies (morphology and behavior), relationships between organisms or groups of organisms (systematics and evolution), methods of identifying organisms (taxonomy), and life cycles (developmental biology).
Explanation:
The collection and preservation of biological organisms, including microbes and their relatives, is increasingly noticed. Although one can study and enjoy microbes without killing them through observational and photographic methods, there are several reasons or advantages for obtaining specimens:
1. Microbes identification is a branch of the study of microbes (microbiology) based on the research of taxonomists which describe species or groups of species (eg: genera, orders, genera, etc.). Through collection and preservation, new species are discovered and described. There are still many undescribed microbes in the world, even in Texas.
2. Properly preserved and preserved microbes specimens can be enjoyed and studied for hundreds of years, while most microbes live only days to months before dying and decaying. Specimens in museums, together with information on specimen labels, form a historical record of biodiversity and can be used to document changes in species distribution and abundance over time. Some museums have specimens of extinct microbes species.
3. The names and identities of microbes (and other organisms) change over time as new research indicates the need for a name change. If the specimens were used as a basis for scientific research, the voucher specimens will be presented and preserved in a recognized insect collection of repute. Only then can future researchers be sure that the species mentioned in these studies have been accurately identified. In some cases, specimens that appeared to be identical to early researchers are later found to represent two or more species through additional studies or new techniques.
