Se realizó la caracterización de ficoeritrina de la cepa A5 de Nostoc sp., seguida de investigación de su actividad biológica para aplicaciones biotecnológicas. Para la extracción de ficoeritrina, el uso de tampón acetato (pH 5.1) produjo 65.04 µg mL-1, y se identificó como C-ficoeritrina. Los resultados de su actividad antioxidante sugirieron su acción como un potente eliminador de radicales libres. Además, la C-ficoeritrina de Nostoc mostró una capacidad notable como agente antibacteriano y antifúngico, con estabilidad significativa de hasta 10 días. La glucosa (4 mg mL-1) fue un buen conservante para la C-ficoeritrina a 25 y 4 ºC. Se obtuvo por primera vez una C-ficoeritrina estable de Nostoc sp. en condiciones de sequía en piedra caliza, lo que demuestra la necesidad de estudiar microorganismos de ambientes extremos.

Results of its antioxidant activity suggested action as a potent free radical scavenger. In addition, Nostoc's C-phycoerythrin showed noteworthy ability for antibacterial and antifungal agents with significant stability up to 10 days. Glucose (4 mg mL-1) was a good preservative for C-phycoerythrin at 25 and 4 ºC. A stable C-phycoerythrin from Nostoc sp. was obtained for the first time from limestone drought conditions, showing the need of studying microorganisms from extreme environments.

Los datos pueden usarse como una herramienta para la identificación y clasificación de Pinus hasta el nivel de género y especie. También encontramos que la similitud y las diferencias en los rasgos anatómicos de la hoja respaldaban la filogenia molecular de Pinus realizada por varios investigadores. Comprehensive and detailed anatomy of needles in ten species of Pinus using four morphological traits and nine anatomical traits was carried out.

El Material Particulado (MP) puede alterar los procesos cognitivos, el comportamiento depresivo y hematológico en el modelo animal. El objetivo fue evaluar los efectos causados por MP en los parámetros conductuales, hematológicos y bioquímicos en un modelo animal. Se observaron alteraciones en la actividad locomotora de las ratas, donde hubo una disminución significativa en la locomoción del Grupo 3 (MP10) en comparación con los Grupo 1 (Control) y Grupo 2 (MP2,5). Con respecto al comportamiento de ansiedad, el Grupo 3 pasó significativamente más tiempo en brazos abiertos en comparación con el control y MP2,5. No se observaron cambios hematológicos y bioquímicos. En este estudio, se concluye que, la exposición a la MP puede causar daño neurológico y, en consecuencia, afectar a otros sistemas. Particulate matter (PM) can alter the cognitive processes, the depressive behavior, and the hematological profile in animals. This study aimed to evaluate the effects on behavioral, hematological, and biochemical parameters caused by PM in an animal model. A significant decrease in the locomotion activity of Group 3 (PM10) in relation to Group 1 (Control) and Group 2 (PM2.5) was observed. Regarding the anxiety behavior, Group 3 remained significantly the most part of the time in the open arms when compared to the control and PM2.5 groups. No hematological or biochemical alterations were observed among groups. In this study, we concluded that the exposure to particulate matter can cause neurological damages, and consequently, affect other systems.

Jatropha mollissima es una planta endémica del bioma Caatinga, Brasil. Existen informes en la literatura de que esta especie tiene acción antioxidante, antibacteriana y antiproliferativa. El presente estudio tuvo como objetivo evaluar el potencial antibacteriano y modulador de J. mollissima contra cepas bacterianas multirresistentes. El perfil fitoquímico se obtuvo por cromatografía de gases junto con espectrometría de masas. J. mollissima mostró actividad antibacteriana moderada y moduló la actividad del antibiótico Norfloxacino, promoviendo una relación antagonista.

The emergence of resistant bacterial strains and the significant increase in side effects of currently available antibacterial drugs have made it urgent to develop research to identify new bioactives antibacterial compounds. Jatropha mollissima is a plant endemic to the Caatinga biome, Brazil and this species has antioxidant, antibacterial and antiproliferative action. The present study aimed to evaluate the antibacterial and modulatory potentials of J. mollissima against multiresistant bacterial strains.

Bioproductos de la industria de la yuca: sustratos alternativos para la producción de ciclodextrina glucosiltransferasa por alcalófilo Bacillus trypoxylicola SM-02 En el presente trabajo estudiamos el uso licor de maíz fermentado (LMF), harina de cáscara de yuca (HCY) y aguas residuales de yuca para la producción de ciclodextina glicosiltransferasa (CGTase) por un nuevo aislado alcalófilo de Bacillus trypoxylicola SM-02 en fermentación sumergida. Los experimentos se realizaron por Diseño Central Compuesto Rotativo 22 totalizando 11 ensayos. La mayor actividad enzimática de 352.53 U/mL se obtuvo con 1.5 g de HCY y 0.6 g de LMF. La temperatura y el pH óptimos fueron 55 ºC y pH 8.0, respectivamente. CGTase mostró una actividad relativa superior al 50% durante 120 min. a la temperatura óptima. Solo el CaCl2 mostró actividad positiva para CGTasa. Los resultados apuntaron a un buen potencial de B. trypoxylicola SM-02 para la producción de CGTasa usando substratos residuales. In the present work was studied the use of cassava peel flour (CPF), corn steep liquor (CSL), and cassava wastewater as substrates to produce cyclodextrin glycosyltransferase (CGTase) from a new alkalophilic isolate of Bacillus trypoxylicola SM-02 by submerged fermentation. The experiments were performed as a Central Composite Design 22, totalizing 11 assays. An enzymatic activity of 352.53 U/mL was obtained using 1.5 g of CPF and 0.6 g of CSL. The optimum temperature and pH of CGTase was 55 °C and 8.0, respectively. The CGTase depicted a relative activity of more than 50% for 120 min at the optimum temperature. The only salt that positively influenced the CGTase activity was CaCl2. The results are indicative of a potential role of B. trypoxylicola SM-02 in the production of CGTase using residual substrates.

Se cita por primera vez en la provincia de Alicante (península ibérica) la especie de planaria terrestre exótica Bipalium cf. kewense Moseley, 1878. Con esta presencia aumenta el área de distribución de la especie en la Comunidad Valenciana, siendo la más meridional. Dado que la especie está considerada en esta comunidad autónoma como especie exótica invasora, se valora el riesgo potencial de colonización de ambientes naturales limítrofes a la zona de observación (jardín privado en zona urbanizada). The non-indigenous terrestrial flatworm Bipalium cf. kewense Moseley, 1878 is reported in Alicante province (Iberian Peninsula) for the first time. This occurrence is the most meridional from the Comunidad Valenciana, enlarging its distribution in this area. As the species is considered an invasive alien species in this region, the potential risk of colonizing natural environments closer to the observation area is evaluated.

Treinta estaciones en el Parque Nacional El Kala (Noreste de Argelia) fueron objeto de un inventario florístico que se centró en el estudio de la ecología de geófitos bulbosos y tuberosos. La flora se caracteriza por una alta proporción de taxones raros y/o endémicos, entre ellos, 6 especies son endemismos algero-tunecinos pertenecientes a la familia Orchidaceae. En este trabajo, se da a conocer la presencia de una nueva especie para la flora argelina, Ophrys fusca subsp. lupercalis. Los análisis multivariantes revelaron, ciertas variables ambientales que determinan la distribución de los geófitos. Los lugares de interés son particularmente sensibles a las amenazas, particularmente las de origen antrópico. Thirty stations at the El Kala National Park (North Eastern Algeria) were the subject of a floristic focused on the study of the ecology of bulbous and tuberous geophytes. The floristic analysis was used to draw up a checklist of 67 species belonging to 36 genera and 14 families, among of which 19 species a high proportion of rare and/or endemic taxa; among them six signed taxa are endemic to algerian-tunisian mainly represented by family of Orchidaceae. In this work, we recorded the presence of a new species for the Algerian flora which is Ophrys fusca subsp. lupercalis. Multivariate analyses revealed certain environmental variables determining the distribution of geophytes. The visited sites show an alarming vulnerability and subject to threats, particularly anthropogenic ones.
