Abstract The aim of this research was to evaluate the efficiency of aqueous alkali-treated Brachiaria straw for the cultivation of appropriate species of oyster mushroom. The substrate used in the cultivation of various Pleurotus spp. was soaked for 20 min by using two different procedures: (i) 0.5-2.0% ...

Background: the growth of world aquaculture has generated important environmental impacts as discard residues that are important sources of protein, which has been used to manufacture low-value products, such as animal food, fish flour and fertilizers. Objectives: to evaluate the effect of enzyme and sub...
Abstract INTRODUCTION: Candida parapsilosis complex species, frequently found in hospital environments, have gained importance as etiological agents of candidemia. METHODS: Candida parapsilosis complex isolates from a nosocomial environment were identified and their hydrolitic enzyme activity and abili...
Background: Inferior Tieguanyin oolong tea leaves were treated with tannase. The content and bioactivity of catechins in extracts from the treated tea leaves were investigated to assess the improvement in the quality of inferior Tieguanyin oolong tea. Results: Analysis showed that after treatment, the es...

Background: The hydrolysis of keratin wastes by microorganisms is considered a biotechnological alternative for recycling and valorization through keratinolytic microorganisms. Despite their resistant structure, keratin wastes can be efficiently degraded by various microorganisms through the secretion of...

O objetivo deste estudo foi avaliar a utilização do hidrolisado proteico de resíduo de sardinha como atrativo na alimentação do Rhamdia quelen. No experimento 1, foram utilizados os seguintes atrativos alimentares: 1. extrato aquoso de músculo de tilápia-do-Nilo (controle positivo); 2. hidrolisado...
Se realizó un estudio in vitro donde se evaluaron once sistemas adhesivos, para establecer si las condiciones de trabajo clínico favorecen su eficiencia. Se plantea que los sistemas adhesivos autoacondicionantes presentan menor estabilidad térmica que los convencionales. Determinar el comportamiento t...
Abstract This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial com...

Background: Biomineralization is a significant process performed by living organisms in which minerals are produced through the hardening of biological tissues. Herein, we focus on calcium carbonate precipitation, as part of biomineralization, to be used in applications for environmental protection, mate...
