The cold-resistant bacteria in milk are predominated by Gram-negative genera (Pseudomonas, Achromobacter, Aeromonas, Serratia, Alcaligenes, Chromobacterium
, and Flavobacterium spp.
The complex of signaling molecules and receptor proteins trigger the expression of specific genes responsible for various phenotypes including violacein pigment in Chromobacterium
violaceum (CviI/R), virulence factors production and biofilm formation in Pseudomonas aeruginosa (LasI/R).
Additionally, many, if not all, commercially useful extracellular lipases are isolated from different bacterial species, including Bacillus achromobacter, Alcaligenes, Arthrobacter, Staphylococcus chromobacterium
and Pseudomonas (Qamsari et al.
violaceum is a Gram-negative, free-living betaproteobacterium that dominates a variety of ecosystems in tropical and subtropical regions.
M2 EQUITYBITES-September 12, 2014-Marrone Bio Innovations wins patent for Chromobacterium
to control corn rootworm
Phenolic components of ginger (Zingiber officinale), for example gingerol, shogaol and zingerone, have exhibited quorum-sensing inhibitory activity (QSI) against Chromobacterium
violaceum and Pseudomonas aeruginosa, (2) Chemical modification of shogaol to azashogaol and an isoxazoline derivative of gingerol were prepared, both of which exhibited good QSI activity.
It is naturally derived from the bacterium Chromobacterium
subtsugae Strain PRAA4-1T (Martin et al.
Two different AHL biosensors strains were used to detect AHL-lactonase activity, Chromobacterium
violaceum CVO26 (mini Tn5 mutant of 31532) (McClean et al.
In addition to these species, several other aquatic bacteria have recently been identified as emerging causes of superficial and invasive infections following marine injuries and exposures, including marine mammal (dolphins and seals) Brucella species, Chromobacterium
violaceum, Comamonas species, Shewanella algae, and Streptococcus iniae.
Using as biosensor Chromobacterium
violaceum ATCC 31532 and Escherichia coli pSB403, the compounds chlorogenic acid (2), isoorientin (3), orientin (4), isovitexin (6), vitexin (7), and rutin (9) were identified as QS inhibitors.
