VL - 12 IS - 3 SE - DO - 10.17268/sci.agropecu.2021.033 UR - https://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/3678 SP - 303-309 AB - <p>Essential oils are products from aromatic plants, which, due to their biological, allelopathic, antioxidant and antimicrobial effects, are important for food preservation. <em>Kajikia audax</em> is a fish of great commercial importance, however, it is highly perishable, requiring strategies to extend its shelf life. <em>In vitro</em> antimicrobial activity of <em>Bursera graveolens</em> essential oil was determined against microorganisms isolated from <em>K. audax</em>. Essential oil was extracted by steam distillation, obtaining a yield of 1.25%, a density of 0.83 g/ml and a refractive index of 1.473°, in addition, it was determined by GC-MS that <em>D</em>-limonene (77.6%) is the majority compound. Antimicrobial tests showed that the minimum inhibitory concentration (MIC) for <em>Aeromonas salmonicida</em> and <em>Pichia kudriavzevii</em> was 1.62 mg/ml and 6.48 mg/ml respectively, and the minimum bactericidal concentration (MBC) was 25.92 mg/ml for both microorganisms. <em>Pseudomonas aeruginosa</em> showed total resistance against the concentrations used. <em>B. graveolens</em> essential oil turned out to be a potential product to control the growth of microorganisms isolated from <em>K. audax</em>, however, it should be tested against species of the genera <em>Vibrio, Flavobacterium, Shewanella, Lactococcus</em> and <em>Streptococcus</em> that cause spoiling of hydrobiological products.</p> ER -
