Citrus peels can be used to make compost. In this compost are found essential oils composed of terpenoids, being the limonene the most abundant. Pseudomonas sp. is bacteria capable of growing in different environment and using available compounds as carbon source even it uses hydrocarbons. Through this study we will evaluate the effect of the use of citrus peels on the growth of Pseudomonas sp in soil under experimental conditions, where the largest colony count of Pseudomonas sp. was obtained in the treatment of soil with lemon peel. Thus demonstrating that Pseudomonas sp. can degrade the essential oils of citrus peel, to meet their nutritional needs.
