“…It is known that nitrogen fixation can influence plant growth (Pavlova et al, 2017) and insect longevity (Behar et al 2008). Another strain of K. oxytoca isolated from the gut of Poekilocerus pictus was shown to degrade oleic acid to produce the smaller-chain fatty acids (Kingsly, Jothinathan, & Thilagaraj, 2017). This bacteria species has also been found to utilize glycerol and xylose as the carbon source to yield chemical products (Cho et al, 2015).…”

The sterile insect technique (SIT) as an eco‐friendly and reliable strategy has been used to control populations of insect pests of agricultural, veterinary and human health importance. Successful applications of SIT rely on the high‐level ecological fitness of sterile males. A suitable and stable gut microbiome can contribute to the ecological fitness of insect by influencing their physiology, biochemistry and development processes. Here, we show that a shift in the gut bacterial composition and structure by sterilizing irradiation, characterized by a decrease in the major gut microbiota community Enterobacteriaceae, an expansion of the minor members (e.g., Bacillaceae) and a higher richness and diversity, is tightly linked to radiation‐induced ecological fitness (male mating competitiveness, flight capacity, survival rate and life span) decline in Bactrocera dorsalis (Hendel) sterile males. Function prediction of gut microbiota indicated that changes in microbiome taxonomy tend to drive microbiome functional shifts. A higher nutrient consumption of the flourishing minor gut microbiota may cause a decline in nutrients and energy metabolic activity of host and then result in the reduced ecological fitness of irradiated flies. Furthermore, we found that a gut bacterial strain Klebsiella oxytoca (BD177) can restore ecological fitness by improving food intake and increasing haemolymph sugar and amino acid levels of irradiated B. dorsalis flies. Our findings suggest that gut symbiont‐based probiotics can be used as agents for reversing radiation‐induced ecological fitness decrease.

“…Klebsiella oxytoca ha sido utilizada con fines biotecnológicos en diversas áreas, presenta potencial biorremediador, pues degrada hidrocarburos [11], compuestos orgánicos hidrofóbicos [12], sustancias tóxicas como el cianuro [13], así como insecticidas organoclorados [14], nitrilos [15], ácidos benzoicos [16], colorantes azoicos [17] y el fármaco diclofenaco [18]. Además, se ha reportado la producción de bioelectricidad en conjunto con la degradación de ácidos grasos [19], ha sido capaz de llevar a cabo la desulfuración termofílica de dibenzotiofenos [20], entre otras muchas aplicaciones [21] [22] [23].…”

Las bacterias endófitas son aquellas que viven en el interior de las células o los tejidos de plantas superiores sin causar daño. Klebsiella oxytoca es una bacteria endófita promotora del crecimiento vegetal y con efecto biocontrolador, razón por la cual, el objetivo del presente estudio fue determinar las condiciones óptimas de crecimiento de esta bacteria, en matraz y en biorreactor, obtenida de plantas de higo (Ficus carica) en estudios anteriores. Para esto, se evaluó el crecimiento de la biomasa de K. oxytoca en caldo nutritivo bajo diferentes condiciones de agitación y temperatura en matraz, determinando que las condiciones a 200 rpm y 30 °C fueron las que produjeron una mayor biomasa. Posteriormente, utilizando medio caldo nutritivo en el biorreactor de 3,7 L, se determinó que una agitación de 500 rpm presenta valores de KLa más altos y tiempos de fermentación menores que si se trabaja a 750 rpm. Además, bajo una agitación de 500 rpm, se determinó que medios basados en residuos agroindustriales pueden funcionar como fuentes de crecimiento alternativas para este microorganismo. Por último, el tratamiento de caldo nutritivo a 500 rpm fue modelado mediante el modelo logístico y la ecuación de Pirt, obteniendo, en ambos casos, coeficientes de determinación superiores a 0,95.
