We describe the environment effects on the amount and quality of resources collected by Melipona rufi ventris Lepeletier in the Atlantic Forest at Ubatuba city, São Paulo state, Brazil (44o 48’W, 23o 22’S). Bees carrying pollen and/or nectar were captured at nest entrances during 5 min every hour, from sunrise to sunset, once a month. Pollen loads were counted and saved for acetolysis. Nectar w...

This study aimed to optimize medium composition biosurfactant production of achromobacter xylos using response surface quadratic model . Lipoprotein and lipopeptides are used in many industries such as petroleum refining, pharmaceutical, mining, agriculture bioprocess industries. The point this assessment was pull out portray the passing on restriction microorganisms from oil corrupted soil con...

Aim: Fungi that can tolerate unfavorable conditions are a potential source of stable bioactive metabolites be used for various industrial processes. Therefore this study aimed to isolate halotolerant and halophilic fungi from the Iko river estuary screen them three industrially important enzymes: amylase, cellulase, mannanase.
 Place Duration Study: Department Microbiology, Akwa Ibom State...

Background: Acetic acid bacteria (AAB) are an essential and diverse group of involved in producing fermented foods beverages, primarily known for their production acetic (ethanoic acid) used the vinegar.
 Aim: This study aims to isolate Acid Bacteria from protein waste quantify produced which will serve as a means management/recycling conserve environment/society at large while value-added...

Gametophytic selection was examined as a breeding tool in developing Phalaenopsis hybrids that are more cool or warm temperature tolerant. Two hybrid Phalaenopsis, P. (Taisoco Windian × Sogo Yukidian) by P. hybrid unknown, were reciprocally crosspollinated and exposed to 14°C/9°C for 7 days as a cold pollination treatment. Plants were pollinated again and exposed to 30°C/25°C for 3 days for the...

RESUMEN: La distribución del agua en una PEMFC afecta su comportamiento y durabilidad, por tanto la comprensión de los mecanismos fundamentales del transporte del agua es imperativa y pueden ser fuertemente influenciados mediante estrategias apropiadas de control. Se ha desarrollado un modelo dinámico, no isotérmico, bidimensional de una PEMFC autohumidificada y de cátodo abierto. El modelo con...

Dear Editor, Despite major advances in dentistry and dental prostheses, complete removable dentures are still widely used for oral rehabilitation of edentulous people. Denture surfaces prepare a favorable environment for adherence and proliferation of oral endogenous microorganisms, which is a crucial first step in the initiation of biofilm formation, caused denture stomatitis. Candida species ...

Introduction: Gully features were first observed in the images taken by MOC in impact craters, south polar pits and large martian valleys [1], tending to midlatitudes [2]. HiRISE imagery supports the conclusion that the gullies were formed by fluvial erosion [3], but the source and composition of this fluid is unclear. The superposition of the gully aprons over aeolian features, e.g. dunes, sug...
