In order to determine the colony count, 1 ml of water in each case is pipetted into a sterile Petri culture dish and mixed with sterile nutrient gelatine or sterile nutrient agar. Nutrient gelatine is liquefied in a water bath at 33 °C and cooled to about 30 C before pouring into the culture dish. Nutrient agar is liquefied in boiling water and cooled to 6 2 C... 

Nutrient gelatine solidifies at temperatures below 23 C and cooling is therefore necessary in certain circumstances. 

In the case of nutrient gelatine, too long a period of heating must be avoided since otherwise the gelatine will lose its ability to solidify. 

Glycine A non-essential amino acid. It is found primarily in gelatin and silk fibroin and used therapeutically as a nutrient. It is also a fast inhibitory neurotransmitter. [NIH]... 

As the examples in Table 11.5 indicate, many familiar products are colloids. The cleaning ability of soap is due in part to dirt particles emulsifying in the soap. Food and other nutrients in our blood are transported to cells as colloidal particles. The process of jelly making involves producing a sol that sets up as a semisolid. A similar process occurs when making gelatin. Sols that set up like jellies are technically called gels.

Natural media are those used on the basis of experience and not on the basis of exact knowledge of their composition and action. Natural or complex media usually contain peptones, beef extract, or yeast extract. When a solid medium is desired, a solidifying agent such as gelatin or agar may be incorporated into the medium. Examples of a relatively simple liquid and a solid medium that support the growth of many common heterotrophs are nutrient broth and nutrient agar. Their composition is as follows ... 

Remark 1 Gelatin solution gel is an excellent nutrient for most forms of microbiological life. Hence, a number of manufacturers produce a highly concentrated solution of non-gelling hydrolyzed gelatin preserved with SO2. 

Intercellular Volume and Penetration. The surface coats of epidermal cells occupy intercellular space and these gelatinous layers probably act as watery diffusion channels for nutrients (35). Surface coats are quite different from keratinized intercellular cement (32, 43) kera-tinization modifies desmosomes and intercellular materials to resist diffusion and premature separation in SC (32, 43, 44). 

Microbial mats are communities in surface water ecosystems where bacteria and bacterial processes dominate. In microbial mats dissolved nutrients and metabolites are transformed by one-dimensional (vertical) molecular diffusion. The distinction between microbial mats and biofilms is not sharp. By definition (Fenchel et al, 1998), microbial mats are typically stratified vertically with respect to different functional types of bacteria. Microbial mats are thicker (often several millimeters) than biofilms. In microbial mats various types of filamentous prokaryotes are the most conspicuous part and they are responsible for the mechanical coherence of the mat. The mechanical stability of microbial mats is reinforced by the bacterial excretion of mucous polymers, producing a gelatinous matrix.
