General description

Agar is a complex gelatinous carbohydrate, and is added to the LB broth (Lysogeny broth, Luria broth, Lennox broth, or Luria-Bertani medium), in order to form gel for bacteria to grow upon. LB Broth is the most widely used nutritionally rich medium, for the culture and growth of bacteria. There are several different formulations of Lb broth, but the composition is generally the same comprising of peptides and casein peptones, trace elements, mineral and vitamins.
Agar has been used as reagent for the following studies:
  • Plant cell culture studies.
  • As medium supplement for the growth of wild-type Arabidopsis thaliana (ecotype Columbia) and transgenic seeds.
  • For the solidification of culture medium of cork oak somatic embryos.
  • It may be used for incubation of single antibody-forming cell to investigate the plaque formation.
  • Agar suspension culture may be used for the analysis of cell transformation of palyoma virus.

The emergence of Staphylococcus aureus strains resistant to 'last resort' antibiotics compels the development of new antimicrobials against this important human pathogen. We found that propyl 5-hydroxy-3-methyl-1-phenyl-1H-pyrazole-4-carbodithioate (HMPC) shows bacteriostatic activity against S. aureus (MIC = 4 μg/ml) and rescues Caenorhabditis elegans from
