“…Isman (2000) reported that some plant essential oils not only repel insects, but have contact and fumigant insecticidal actions against specific pests, and fungicidal actions against some important plant pathogens. In particular, the antimicrobial properties of thymol has been described extensively, mostly based on observations from semi-quantitative diffusion techniques or microtiter plates assays (Michiels et al 2007). Other authors have studied the effect of thymol on airborne microbes (bacteria, yeasts and moulds), and they concluded that several microbial populations in air declined due to the effect of thymol application.…”

The effect of different dosages of thymol alone, iprodione alone and combinations of thymol and iprodione on white rot disease of garlic and its impact on soil microbial community structure were investigated under greenhouse conditions. Thymol alone or in combination with the fungicide iprodione did not appear to reduce either white rot incidence or soil sclerotia density as compared to an infected control. However, iprodione alone or in combination with thymol reduced soil fungal biomass. In addition, iprodione alone decreased soil microbial activity as estimated by fluorescein diacetate (FDA). Soil bacterial community structure as estimated by phospholipid fatty acid (PLFA) profiles was also was affected by both thymol and iprodione applications. The correlation biplot of the individual PLFAs and biocide treatment indicated that the treatments with thymol alone increased cyclopropyl fatty acid (cy17:0 and cy19:0), while the treatments with iprodione alone increased some saturated and branched fatty acids (principally i16:0, a15:0 and 18:0). In addition, taking into account PLFA biomarkers, thymol applications reduced Gram-negative bacteria in soil. To our knowledge, this research is the first report about the effect of a monoterpene (thymol) on soil microflora.

“…Liu et al (2008) concluded that phenolic compounds due to their hydrophobicity are able to disintegrate the outer membrane of gramnegative bacteria, and disturbing the bacterial structure. Likewise, Michiels et al (2007) concluded that phenolic compounds can especially be used to reduce the bacterial population in the proximal and more acidic parts of the gastrointestinal tract. 2) Indirect effect of plant extracts have been reported due to reducing ileal pH value (which, unfortunately has not been executed in this experiment), while increasing the number of lactic acid bacteria and decreasing the co liform counts in the ileum and caecal contents of broiler chickens (Vidanarachchi et al, 2006).…”

The effects of three plant extracts, i.e. lemon peel extract (LPE), orange peel extract (OPE) and Curcuma xanthorrhiza essential oil (CXEO), on the performance and gut health parameters of broilers exposed to high temperature was investigated. A total of 336 unsexed Ross 308 broilers were distributed to seven dietary treatments, a control diet and six diets containing 200 or 400 mg kg-1 feed of one of the three products between d 25-38 (12 chicks per pen, four replicates). To induce chronic heat stress, the temperature was increased to 34°C with 50% relative humidity for 5 h daily starting from d 28 until d 38. At d 38, four animals per pen were sampled for morphological characteristics (duodenum, jejunum and ileum) and microbial counts (ileo-cecal contents). Plant extracts did not affect the bird performance. The bursa weight of the control birds was lower (p<0.05) comparing to those fed 400 mg kg-1 OPE and 200 and 400 mg kg-1 CXEO diets. Feeding 400 mg kg-1 of LPE decreased the duodenal villus:crypt ratio compared to control and 200 mg kg-1 OPE fed birds. Plant extracts did not have effect on ileal histo-morphology. Feeding with 400 mg kg-1 of LPE and CXEO caused a decrease in coliform counts in ileum and feeding of 400 mg kg-1 CXEO diet decreased coliform counts in caecum compared to control birds (p<0.05). These results elucidate that CXEO, OPE and LPE might modify some microbial and intestinal traits, but without beneficial effect on performance of broilers under heat stress.

ABSTRACT:Eessential oils are known to possess antimicrobial activity. This review article explains the antimicrobial reaction, application, effects, and characteristics of cinnamaldehyde. Amongst the different essential oils, Cinnamaldehyde is observed to be the most effective antimicrobial agent. The current studies on cinnamaldehyde in the field of microbiology have been highlighted. This review explains the different methods, those are used for antimicrobial evaluation. Additionally, the anti-physiologic effect of antimicrobial agents using microbial respiration rate is also discussed.
