Abstract:
Microbial secondary metabolites are low molecular mass products with unusual structures. The structurally diverse metabolites show a variety of biological activities like antimicrobial agents. Thirty nine bioactive compounds were identified in the methanolic extract of Klebsiella pneumoniae. GC-MS analysis of Klebsiella pneumoniae revealed the existence of the Tricyclo[4.3.1.1(3.8)]undecan-1-amine, 3-Methoxybenzaldehyde semicarbazone, carboxaldehyde , 1-methyl-,oxime ,(Z)-(+), 1,5,5-Trimethyl-6-methylene-cyclohexene, 4-(2,5-Dihydro-3-methoxyphenyl)butylamine, Paromomycin , 9-Borabicyclo[3.31]nonane , 9-mercapto-, Benzenemethanol , 2-(2-aminopropoxy)-3-methyl, Acetamide , N-(6-acetylaminobenzothiazol-2-yl)-2-(adamantan, rin-6-carboxylic acid , 4-(2,5-Dihydro-3-methoxyphenyl)butylamine, N-(2,5-Dicyano-3,4-dihydro-2H-pyrrol-2-yl)-acetamide, 3,10-Dioxatricyclo [4.3.1.0(2,4)]dec-7-ene, 3-Cyclohex-3-enyl-propionic acid, Eicosanoic acid ,phenylmethyl ester, 3,7-Diazabicyclo[3.3.1]nonane , 9,9-dimethyl-, Dithiocarbamate , S-methyl-,N-(2-methyl-3-oxobutyl)-, dl-Homocysteine, 2-(2-Furyl)pyridine, 1,7-Dioxa-10-thia-4,13-diazacyclopentadeca-5,9,12-trione, 5,7-Dodecadiyn-1,12-diol, 1-(β-d-Arabinofuranosyl)-4-O-difluoromethyluracil, Uric acid, Pyrrolo[1.2-a]pyrazine-1,4-dione , hexahydro-,12-Methyl-oxa-cyclododecan-2-one, Phthalic acid , butyl undecyl ester, 9,12,15-Octadecatrienoic acid , 2,3-bis(acetyloxy)propyl ester, 1,2,4-Trioxolane-2-octanoic acid 5-octyl-, methyl ester, 12-Dimethylamino-10-oxododecanoic acid , Octahydrochromen-2-one, L-Aspartic acid , N-glycyl-,2H-Oxecin-2-one , 3,4,7,8,91,10-hexahydro-4-hydroxy-10-meth , Thiazolo[4,5-d]pyrimidine-5,7(4H,6H)-dione , 2-amino-4-(2-ph, Dec-9-en-6-oxo-1-ylamide, 3,6,12-Trimethyl-1,4,7,10,13,16-hexaaza-cyclooctadecane, 2-lodohiistidine, 2,5-Piperazinedione ,3,6-bis(2-methylpropyl)-, 9-Octadecenamide , (Z)-, 3',8,8'-Trimethoxy-3-piperidyl-2,2'-binaphthalene-1,1',4,4'-tetra.
Clinical pathogens selected for antibacterial activity namely, Streptococcus pneumonia, Escherichia coli, Staphylococcus aureus, Proteus mirabilis, Staphylococcus epidermidis, It were 4.09±0.013, 2.99±0.300, 4.37±0.200, 3.22±0.210, and 4.00±0.203 respectively for Bacterial products (Metabolites Produced by Klebsiella pneumoniae), while recorded 1.08±0.200, 0.97±0.116, 2.08±0.233, 3.04±0.261, 0.98±0.166 respectively for Bacterial products Streptomycin antibiotics, and recorded 1.02±0.180, 1.00±0.190, 2.08±0.236, 1.00±0.100, and 1.82±0.200 respectively for Kanamycin antibiotics. Klebsiella pneumoniae produce many important secondary metabolites with high biological activities. Based on the significance of employing bioactive compounds in pharmacy to produce drugs for the treatment of many diseases, the purification of compounds produced by Klebsiella pneumoniae can be useful.
