Food handlers plays a primary role in the transmission of pathogenically important protozoans and helminth parasites. This study was aimed to evaluate the prevalence of intestinal pathogenic protozoans and helminth parasites among food handlers in and around University of Malakand, Lower Dir, Pakistan. S...
Abstract It was evaluated the effect of operational conditions in the production of Chlorella sp. after its selection from genus Chlorella sp., Scenedesmus sp., Nannochloris sp., Tetraselmis sp. and Dunaliella salina. Microalgae were inoculated in drinking water with addition of NPK fertilizer (N 24%, P ...
Abstract To develop a biorefinery concept applied in the brewery industry, Chlorella pyrenoidosa and a consortium of associated bacteria were cultivated mixotrophically in a continuous photobioreactor using brewery low-value subproducts as an integrative process. Beer production residues were biochemical...
Abstract Microalgae are photosynthetic microorganisms whose composition and biomass production can be influenced by manipulating the cultivation conditions employed. However, few studies have evaluated the effects of various cultivation conditions in autotrophic and mixotrophic conditions. The present wo...
BACKGROUND: Microalgae are aquatic chlorophyll-containing organisms comprising unicellular microscopic forms, and their biomasses are potential sources of bioactive compounds, biofuels and food-based products. However, the neuroprotective effects of microalgal biomass have not been fully explored. In thi...

Background: Cultivation of algae for conversion to biofuels has gained global interest. Outdoor raceway cultivation is preferred because of its lower capital and operating costs. A major disadvantage of outdoor cultivation is susceptibility of algal crops to attack by predatory rotifers. In order to quan...
Las microalgas representan en la actualidad una opción atractiva para el desarrollo de nuevos suplementos nutricionales y alimentos para regímenes especiales, mediante la bioconversión de la energía solar en virtud del alto contenido de proteínas y sustancias biológicamente activas en la biomasa ce...
Se estudiaron la composición bioquímica y las características del perfil aminoacídico de la microalga Chlorella vulgaris, cultivada en régimen autotrófico, y se evaluó además la calidad de su proteína mediante métodos químicos. Los resultados evidenciaron que la biomasa de esta especie microal...
Se presentaron las posibilidades de la biomasa de microalga Chlorella sp. como fuente de vitaminas para el consumo humano y animal. Se emplearon métodos espectrofotométricos y cromatográficos, y se desarrolló además una técnica cromatográfica que permitió determinar simultáneamente varias vitami...
A atividade antioxidante das microalgas Chlorella vulgaris, Spirulina maxima e Tetraselmis gracilis foi determinada in vitro através de medidas espectrofotométrica, (sistema ß-caroteno -'ALFA' linoléico) e teste em Rancimat, (medida pelo tempo de induçäo da oxidaçäo do óleo de soja) e ensaio in ...
