  1. Agar is odourless or has a slight characteristic odour. Unground agar usually occurs in bundles consisting of thin, membranous, agglutinated strips, or in cut, flaked or granulated forms. It may be light yellowish-orange, yellowish-grey to pale yellow, or colourless. It is tough when damp, brittle when dry
  2. The original structure of agar was was believed to be a simple sulphated poly galactose. However in in 1937 Araki showed that agar consisted of at least two separate polymers that could be fractionated. One was called agarose and the other agaropectin. Essentially agarose is the gelling fraction of agar
  3. The gels are formed by hydrogen bonds between adjacent chains of repeating units of galactose and 3,6-anhydrogalactose, so no other agents are needed to form a gel. The gel structure is not affected by salts or proteins. The gel hysteresis, or difference between melting and setting points, is much greater for agar than other gelling agents
  4. These clumps can then form larger groupings that from a large porous gel structure. Agar is known to form a very porous gel and the pore size can be roughly measured by assessing the size of particulates that are excluded from the gel in a gel permeation experiment. It has been shown that agar gels can allow molecules up to 30M daltons in size.
  5. The structure of agar gels may differ according to the nature of their solvents and the presence of various solutes (Wunderly, 1960). 26. Irregularity of pore size in agar gels, together with the fact that at given concentrations pore size can vary among agars of different manufacture.
  6. GEL FORMATION AND STRUCTURE In agar gels, helicoidal structures have been verified by X-ray diffraction, similar to those found in carrageenan. However because agar contains 3,6-anhydro-L-galactose, the helices are left-handed whereas in kappa and iota carrageenan, which contains 3,6-anhydro-D-galactose, they are right-handed (dextrogyres)

When the agar cools and solidifies, it diffuses back in, creating a gradient of oxygen concentrations in the medium. This makes the top aerobic and the bottom anaerobic to support a large range of microorganisms. Agar deep stabs are stab-inoculated with a sterile inoculating needle. This is to introduce as little air as possible and the. thawing or by pressing an agar gel.

MacConkey agar is a selective and differential media used for the isolation and differentiation of non-fastidious gram-negative rods, particularly members of the family Enterobacteriaceae and the genus Pseudomonas Agar. Agar is best known to most Americans as the jellylike substance that biologists use to culture bacteria. In Asia, however, it's a gelling agent used to make a variety of desserts. The structure of agar is somewhat similar, from a macroscopic perspective, to that of pectin; like pectin, it's made up of monosaccharide units An Introduction to Agar. With its distinctive smell, one can easily distinguish agar from the other materials commonly found in a laboratory. Chemically, agar is a polymer made up of subunits of the sugar galactose, and is a component of the cell walls of several species of red algae that are usually harvested in eastern Asia and California Agar/agarose.

Agar and Carrageenan. Agar (agar agar) is extracted from seaweed and is used in many foods as a gelling agent. Agar is a polymer of agarobiose, a disaccharide composed of D-galactose and 3,6-anhydro-L-galactose. Highly refined agar is used as a medium for culturing bacteria, cellular tissues, and for DNA fingerprinting the ice structure showing that the agar matrix structure does not affect the ice structure in an agar concen-tration ranging from 1.5 to 5%. Keywords : unidirectional freezing, ice crystal structure, dendrite, diffusion of water In frozen food, ice structure is very important to control its quality (Trgo et al., 1999; Russel et al., 1999; Regan The key difference between agar and agarose is that the agar is a gelatinous substance obtained from red algae while the agarose is a linear polymer purified from agar or red seaweeds..

Gram positive bacteria have a large peptidoglycan structure. As noted above, this accounts for the differential staining with Gram stain. Some Gram positive bacteria are also capable of forming spores under stressful environmental conditions such as when there is limited availability of carbon and nitrogen The structure of the bacterium is very simple as compared to the eukaryotic cells. A typical bacterium is shown and discussed below. Cell wall. Bacteria are protected by rigid cell walls that form envelopes and surround the cells. The cell walls of bacteria are made of peptidoglycan, which is a polysaccharide chain Soyabean Casein Digest Agar is a widely used medium, which supports the growth of wide variety of organisms even that of fastidious ones such as Neisseria, Listeria , and Brucella etc. The medium with addition of blood provides perfectly defined haemolysis zones, while preventing the lysis of erythrocytes due to its sodium chloride content
