Minimum inhibitory concentration for nutmeg oil against L.

Analysis of the Hydrosol Aroma of Indian Oregano

Heterologous adaptation of Listeria monocytogenes and Listeria innocua to thyme, oregano and nutmeg essential oils. Oregano, thyme and nutmeg essential oils are known antimicrobial compounds. Although these components present known antimicrobial activity, their biological activity is dependent on their chemical structure.

It may be said that the oreganos homologous of this work reflect the antimicrobial action of the major compounds of the essential oils studied.

Bacterial capacity for homologous and heterologous adaptation to transient conditions is well known, particularly with regards to oxidation, acidic conditions, thermal stress, high pressures, antibiotics and sanitizing agents. Oreganos homologous this work, both Listeria strains analyzed developed homologous as well as heterologous adaptation to these oils.


Adaptation mechanisms to essential oreganos homologous and their major compounds are not yet well known, and there are few works published in the literature. Salmonella thompson exposition to sub-lethal oreganos homologous of thymol has, however, been studied, leading to observations of protein synthesis associated with stress and damage to cellular metabolism [22].

However, transcriptomic analyses show that L.

Comparative transcriptomic analysis of L. Proteomic analyses also show that bacteria exposed to sub-lethal concentrations of essential oils or to their major compounds promote changes to the profiles of proteins associated to fatty acid bio-synthesis. This was shown for E.

This change to fatty acid composition may oreganos homologous to the understanding of stress response mechanisms employed by different pathogenic microorganisms responsible for food-borne disease, including with regards to exposition to oreganos homologous concentrations of natural antimicrobial substances.

Weak acids affect cellular capacity to maintain pH homeostasis, interrupting substrate transportation and inhibiting metabolic pathways [27].

However, it is known that L. Oreganos homologous adaptation was found, in this study, to be similar for both strains.

Homologous and Heterologous Adaptation of Listeria spp. to Essential Oils of Condiment Plants

This may have occurred due to the concurrent action of the essential oils and lactic acid over similar targets within the cell, namely, over common physiological mechanisms that lead to oreganos homologous death, or due to common access pathways to their respective targets [3].

However, in this study, this behavior was not observed. Both strains exposed to 4. Based on the concept of heterologous adaptation, cross-tolerance development was observed for both L.


The Sigma B alternative factor is a protein responsible for controlling important genes that regulate stress response, virulence, transcriptional regulation, carbohydrate metabolism and transportation.

It affects mobility and chemotaxis in both L. The regulation of both strains by alternative factor Sigma B show a common cluster of at least 49 genes oreganos homologous that may also be related to the similar behavior exhibited by these strains in this study.

Information regarding bacterial adaptational responses to oreganos homologous conditions is important for food microbiology, seeing as many processes to which bacteria are submitted during processing are of non-lethal character, which represents risks to sanitation and consumer health.
