1. OUTDOOR CULTIVATION OF Scenedesmus obliquus BR003 IN STIRRED TANKS BY AIRLIFT
ABSTRACT: The use of microalgae as a source of raw material for biofuel production has been highly targeted. Compared to other biological options for the capture and use of CO2, microalgae crops have the following advantages: high productivity, lack of competition with feed and food-based products, use of unproductive and non-arable land, and allowance of th

2. Keratinolytic abilities of
Micrococcus luteus from poultry wasteKeratinolytic microorganisms have become the subject of scientific interest due to their ability to biosynthesize specific keratinases and their prospective application in keratinic waste management. Among several bacterial classes, actinobacteria remain one of the most important sources of keratin-degrading strains, however members of the

3. Implantação da piscicultura familiar com pescadores e agricultores assentados no Município de Lucena-PB
Fishing is a very important activity for the provision of protein, but as a result of the heavy pressure from extractive fishing and above the limits of carrying capacity of populations of commercial species, many stocks are at or above the limit of exploration, which has resulted in decreased populations of many animals, including driving some to extinction

4. Produção e caracterização de produto fermentado rico em quitooligossacarídeos : efeito na alimentação de aves
Parte da indústria de carne de frango utiliza antimicrobianos que atuam como promotores de crescimento em aves, podendo causar sérios problemas de resistência microbiana. Logo, esta prática pode se tornar algo perigoso, de maneira que, a busca por novos compostos seguros que atuem melhorando o desempenho zootécnico acompanhado de melhora no sistema imun

5. Study of fast pyrolysis of sugarcane bagasse in a bubbling fluidized bed / Estudo da pirolise rapida de bagaço de cana em reator de leito fluidizado borbulhante
The energy content of biomass can be exploited by direct combustion or after conversion by physical, biological and thermochemical processes. Among the thermochemical processes there is the pyrolysis that is an attractive process because it provokes the conversion of solid biomass into liquids products. Such conversion presents many advantages in transport,

6. Aproveitamento do resíduo do beneficiamento da Tilápia do Nilo (Oreochromis niloticus) para obtenção de silagem e óleo como subprodutos. / Utilization of fish waste from the processing of nile tilapia (Oreochromis niloticus) to obtain fish silage and fish oil as by-products.
One third of the world fishing produce is not directly applied in human consumption. Instead, it is used in the elaboration of feed or wasted as residue. It would be ideal to use the raw material thoroughly and to recover by-products, preventing the generation of residues. With the objectives of increasing the income and the production of the industry, as we

7. Soybean oil processing using ultrafiltration in micelle in the degumming step / Processamento de oleo de soja utilizando ultrafiltração em miscela na etapa de degomagem e na obtenção de lecitina
Crude soybean oil is traditionally degummed by water addition or phosphoric acid. The membrane technology applied to vegetable oils processing has become important because it allows to use temperatures, reduces waste water treatment, retains undesirable products, besides preserving important minor compounds in the oil. The objectives of this work were to opt

8. Controle em destilação batelada : controle adaptativo e controle preditivo com modelo baseado em redes neurais artificiais
Separation processes are very important in chemical industries where batch distillation appears as one of its oldest processes. Over the last few years batch processing has received renewed attention because of the growing interest in the production of high-technology, high-value added chemical and biochemical products and also in environmental problems of i

9. Optimized Batch Fermentation of Cheese Whey-Supplemented Feedlot Waste Filtrate to Produce a Nitrogen-Rich Feed Supplement for Ruminants †
An optimized batch fermentation process for the conversion of cattle feedlot waste filtrate, supplemented with cheese whey, into a nitrogenous feed supplement for ruminants is described. Feedlot waste filtrate supplemented with cheese whey (5 g of whey per 100 ml) was fermented by the indigenous microbial flora in the feedlot waste filtrate. Ammonium hydroxi

10. Terminal Reactions in the Anaerobic Digestion of Animal Waste †
An anaerobic mesophilic digestor was operated using beef cattle waste (diluted to 5.75% volatile solids) as substrate; retention time was 10 days with daily batch feed. Volatile solids destruction was 36%. Daily gas production rate was 1.8 liters of gas (standard temperature and pressure) per liter of digestor contents (0.99 liters of CH4 per liter of digest

11. Salmonella Types Isolated from the Gulf of Aarhus Compared with Types from Infected Human Beings, Animals, and Feed Products in Denmark
A 2-year examination for Salmonella was conducted in the gulf of Aarhus, which receives waste water from local industries and from about 100,000 inhabitants. An approximately rectilinear relationship is shown between the most probable number of Escherichia coli and species of Salmonella. Salmonella species can be demonstrated with the same frequency in inlet
