Chlorine dioxide against bacteria and yeasts from the alcoholic fermentation
(Soc Brasileira Microbiologia, 2008-04-01)
The ethanol production in Brazil is carried out by fed-batch or continuous process with cell recycle, in such way that bacterial contaminants are also recycled and may be troublesome due to the substrate competition. ...
Electrocoagulation/flotation followed by fluidized bed anaerobic reactor applied to tannery effluent treatment
(Desalination Publ, 2012-01-01)
A series operation of electrocoagulation/flotation (ECF) and fluidized bed anaerobic reactor (FBR) was conducted to treat tannery wastewater. Although both reactors were operated in fill-and-draw (batch) mode, effluent ...

Effect of C/N Ratio and Physicochemical Conditions on the production of Rhamnolipids by Pseudomonas Aeruginosa LBI
(Research Journal Biotechnology, 2010-08-01)
Waste utilization for biosurfactant production is an important approach contributing to the reduction of waste treatment costs, while increasing the economic value of residues and reducing biosurfactant production costs: ...
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) production from biodiesel by-product and propionic acid by mutant strains of Pandoraea sp.
(2017-07-01)
Pandoraea sp. MA03 wild type strain was subjected to UV mutation to obtain mutants unable to grow on propionic acid (PA) but still able to produce poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] from glycerol ...
Hydrogen bioproduction with anaerobic bacteria consortium from brewery wastewater
(2018-01-01)
Biohydrogen production is a cheap and clean way to obtain hydrogen gas. In subtropical countries such as Brazil the average temperatures of 27 °C can favor the hydrogen producing bacteria growth. A mixed culture was obtained ...
Thermal characterization of granular sludges from biologic treatments and its application to the generation of biogas
(Springer, 2019-12-01)
The application of granular sludge from biological treatment plants can become an economically and environmentally viable process as a renewable source of energy. It is available in most countries, and its application can ...
Ethanol biosynthesis by fast hydrolysis of cassava bagasse using fungal amylases produced in optimized conditions
(Elsevier B.V., 2018-02-01)
The search for a renewable platform to produce high-value biochemicals and energy that are environmentally correct has been a current concern. A fast and inexpensive bioprocess for amylase production, able to hydrolyze ...
Zinc determination in samples fish by GFAAS using acid digestion in an ultrasound bath
(2016-03-01)
The aim of this paper was to determine the zinc concentrations in muscle samples of Nile tilapia (Oreochromis niloticus) produced in aquaculture and fed diets containing inorganic and organic zinc sources. In the sample ...
Enrichment of Autotrophic Denitrifiers From Anaerobic Sludge Using Sulfurous Electron Donors
(2021-06-07)
This study compared the rates and microbial community development in batch bioassays on autotrophic denitrification using elemental sulfur (S0), pyrite (FeS2), thiosulfate (S2O32–), and sulfide (S2–) as electron donor. The ...
