This study evaluates the synergistic antifungal effects between thyme essential oils and Lactobacillus plantarum cell-free supernatant (LCFS) against Penicillium spp. and in situ antifungal activity in rice grains. Thyme essential oil and LCFS showed remarkable antifungal activities against Penicil- Practical applicationsEssential oils are used as preservative in food industry and high concentration of essential oil is associated with negative organoleptic characteristics. This study presented a novel approach for synergistic antifungal effects by using the combination of thyme essential oil and Lactobacillus plantarum cell-free supernatant (LCFS) against Penicillium spp. and systematic evaluation of the antifungal effect by using fractional inhibitory concentration (FIC) index method. This approach will be a role model for future research on synergism and overcome the major drawbacks of using live bacteria and the negative effects arising from antimicrobial activities of essential oils.

“…However, Aspergillus flavus produces aflatoxin, a compound potentially harmful to the environment and human health 20 and Streptomyces somaliensis produces several secondary metabolites (i.e., streptomycin), which inhibit the growth of other microorganisms 21 . These two species were excluded from further study.…”

Large quantities of kitchen waste are produced in modern society and its disposal poses serious environmental and social problems. The aim of this study was to isolate degradative strains from kitchen waste and to develop a novel and effective microbial agent. One hundred and four strains were isolated from kitchen waste and the 84 dominant strains were used to inoculate protein-, starch-, fat- and cellulose-containing media for detecting their degradability. Twelve dominant strains of various species with high degradability (eight bacteria, one actinomycetes and three fungi) were selected to develop a compound microbial agent “YH” and five strains of these species including H7 (Brevibacterium epidermidis), A3 (Paenibacillus polymyxa), E3 (Aspergillus japonicus), F9 (Aspergillus versicolor) and A5 (Penicillium digitatum), were new for kitchen waste degradation. YH was compared with three commercial microbial agents—“Tiangeng” (TG), “Yilezai” (YLZ) and Effective Microorganisms (EM), by their effects on reduction, maturity and deodorization. The results showed that YH exerted the greatest efficacy on mass loss which decreased about 65.87% after 14 days. The agent inhibited NH3 and H2S emissions significantly during composting process. The concentration of NH3 decreased from 7.1 to 3.2 ppm and that of H2S reduced from 0.7 to 0.2 ppm. Moreover, E4/E6 (Extinction value460nm/Extinction value665nm) of YH decreased from 2.51 to 1.31, which meant YH had an obvious maturity effect. These results highlighted the potential application of YH in composting kitchen waste.

“…Para adaptarse a su ambiente, las plantas producen metabolitos secundarios (Mazid et al, 2011), tales como fenólicos, alcaloides, saponinas, terpenoides y flavonoides que tienen múltiples atributos biológicos, tales como actividad antioxidante, microbicida y antifúngica (Naseer et al, 2014).

The environment in which the fruit of avocado (Persea americana Mill.) cv. Hass determines the characteristics of your skin which represents the first natural barrier and the tissue that interacts directly with the environment. The fruit is exposed to many types of stress and to protect itself produces a wide variety of phytochemicals, called secondary metabolites. It is unknown if aspects such as nutritional composition and skin morphology could also be affected. The study was carried out in commercial Avocado "Hass" orchards with the standard management of each producer in order to determine phytochemical concentrations (total phenolics, total chlorophylls, total carotenoids and lignin) and nutrients (N, P, K, Ca, Mg, S, Fe, Cu, Mn, Zn and B), and to establish their relationship with the roughness of the fruit skin during its development in three regions with different types of climate. The type of climate (warm, semi-warm or temperate) influenced the production of phytochemicals and the roughness of 'Hass'skin. The global analysis showed that the fruits of the warm climate presented the highest concentration of total carotenoids and greater roughness, while in the temperate climate, the roughness was lower. ResumenEl ambiente en el que se desarrolla el fruto de aguacate (Persea americana Mill.) cv. Hass determina las características de su piel la cual representa la primera barrera natural y el tejido que interactúa directamente con el ambiente. El fruto está expuesto a muchos tipos de estrés y para protegerse produce una amplia variedad de fitoquímicos, llamados metabolitos secundarios. Se desconoce si aspectos como la composición nutrimental y morfología de la piel también podrían ser afectados. El estudio se realizó en huertos comerciales de aguacate 'Hass' con el manejo estándar de cada productor con el objetivo de determinar las concentraciones de fitoquímicos (compuestos fenólicos totales, clorofilas totales, carotenoides totales y lignina) y nutrimentos (N, P, K, Ca, Mg, S, Fe, Cu, Mn, Zn y B), y establecer su relación con la rugosidad de la piel de los frutos durante su desarrollo en tres regiones con distinto tipo de clima. El tipo de clima (cálido, semicálido o templado) influyó sobre la producción de fitoquímicos y en la rugosidad de la piel de 'Hass'. El análisis global mostró que los frutos del clima cálido presentaron la mayor concentración de carotenoides totales y mayor rugosidad, mientras que en el clima templado, la IntroducciónLa composición y estructura de los tejidos superficiales de las frutas tiene una notable influencia en su potencial de almacenamiento poscosecha ya que constituyen una barrera contra la pérdida de agua, ataque químico, daños mecánicos e infección microbiana (Lara et al., 2014).
