Impact of oxygen supply on surfactin biosynthesis using brewery waste as substrate
(Elsevier, 2021-03-15)
This work reports surfactin production by B. subtilis ATCC 6051 in a stirred tank bioreactor, where trub was used as a carbon source. Trub is a residue from the brewing industry mainly composed of high-molar-mass proteins ...
A low‑cost brewery waste as a carbon source in bio‑surfactant production
(Dirk Weuster-Botz, 2021-06-22)
This work aims to produce bio-surfactant using a brewery waste (trub) as a strategy to reduce production costs related to the substrate, as well as to provide an eco-friendly destination for this residue. Trub is obtained ...
The use of low-cost brewery waste product for the production of surfactin as a natural microbial biocide
(Elsevier, 2020-10-07)
Surfactin has potential as next generation antibiofilm agent to combat antimicrobial resistance against emerging pathogens. However, the widespread industrial applications of surfactin is hampered by its high production ...
Bioconversion of low-cost brewery waste to biosurfactant: an improvement of surfactin production by culture medium optimization
(Colin Webb, 2021-05-11)
Trub is the second-largest residue from brewing industry (250 thousand tons/year) and, due to the presence of high amounts of carbon and nitrogen, it is a potential source of reducing sugars and nitrogen for biological ...
Uso de substrato compostado no desenvolvimento de mudas florestais nativas
(Universidade Tecnológica Federal do ParanáFrancisco BeltraoBrasilEngenharia AmbientalUTFPR, 2017-06-21)
One of the biggest sociaevironmental problems is related to the production of solid waste. The bigger part of this waste is formed from organic materials that are considered useless. The purpose of this work was to perform ...
Análise do uso de recursos naturais e alternativas para aumentar a eficiência de produção em cervejarias de pequena escala: um estudo de caso
(Universidade Federal de Santa MariaBrasilEngenharia de ProduçãoUFSMPrograma de Pós-Graduação em Engenharia de ProduçãoCentro de Tecnologia, 2022-09-08)
After 2010 there was a significant increase in breweries registered by the Ministry of Agriculture, Livestock, and Supply. Most of the new registrations were from small and medium-sized breweries, which, following a market ...

Análise da adequação à Política Nacional de Resíduos Sólidos da indústria cervejeira da região dos Campos Gerais
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de Engenharia QuímicaEngenharia QuímicaUTFPR, 2020-11-16)
Too much data or studies are not necessary to realize that the continuous population growth over the years is accompanied by an increase in residues from all sources. The high volume of waste generated aroused the sense ...
Dimensionamento de um sistema de wetlands construído de fluxo vertical para pós-tratamento de efluente de cervejaria
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia AmbientalUTFPR, 2020-11-30)
Constructed Wetlands are an innovative and promising technology for the treatment and aftertreatment of industrial effluents, due to their easy operation and very low maintenance periodicity. The present work presents the ...
