Non-thermal inactivation of courgette peroxidase enzyme: Response surface modeling the effect cumin, fennel and clove essential oils

Uropathogenic organisms have evolved numerous defense mechanisms against antimicrobial agents, hence resistance to old and newly available drugs are increasing at an unprecedented level. The events of antibiotic resistance have lead for screening of several medicinal plants for their potential antimicrobial activity. The aim of this study was to evaluate the antimicrobial efficacy of Cyminumcum...

The cometabolic degradation of trichloroethene (TCE) by Rhodococcus sp. L4 was limited by the loss of enzyme activity during TCE transformation. This problem was overcome by repeated addition of inducing substrates, such as cumene, limonene, or cumin aldehyde, to the cells. Alternatively, Rhodococcus sp. L4 was immobilized on plant materials which contain those inducers in their essential oils....

A deodorizing substance in black cumin (Nigella sativa L.), a spice for curry and vegetable foods in Southwest Asia, was examined. The essential oil prepared from the seeds of this plant exhibited strong deodorizing activity against methyl mercaptan, which is a main factor in oral malodor. After purification with silica gel column chromatography, the active substance in black cumin seed oil was...

Materials and methods: The rats were randomly divided into four groups of 6 rats each. Group 1 rats received 1.0 ml of 0.5% carboxymethyl cellulose (CMC) throughout the experimental period and served as the control. Group 2 rats received CMC as in group 1 and isoproterenol (85 mg/kg body weight) intraperitoneally twice at an interval of 24 hours on the 14th and 15th days. The rats in group 3 re...

Antibacterial activity of seed extracts of cumin (Cuminum cyminum L.) was investigated against 10 gram positive and gram negative bacteria. Disc diff usion method was used to test antibacterial activity. Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined by using standard procedures. Th e highest (eff ective) inhibition zone of 16.67±0.47 mm was ...

Cumin is an important spice that has been used for centuries in various cuisines around the world. Two cumin varieties (GC 3 and GC 4) were subjected to mutation understand macromutational modifications. Ethyl methane sulphonate (EMS) @ 0.6% gamma rays (190 Gy) significantly reduced germination plant survival percentage as compared 0.2% EMS 130 Gy. Physical mutagens showed higher suravival than...

This study was aimed to investigate the effects of Cuminum cyminum seed aqueous extract on function and histological structure rat kidney treated with dibutyl phthalate (DBP). Eighteen albino rats weighing 190-240g aged 10-12 weeks were used for this which went 28 days. The divided into three groups (each six animals): 1st group: control given food tap water, 2nd group DBP (420mg/Kg. B.W.) wate...
