The process of organic waste biodigestion is quite old, as the first unit was installed in Bombay, India, in 1819; in Australia, a company has produced and industrialized methane from sewage since 1911. China has 4.5 million biodigesters that produce gas and organic fertilizer, the main role of which is sanitation in rural areas. However, different aspects related to biodigesters are still lacking. This work aimed at studying and improving a biodigester system, and its general goal was the devel

Bovine mastitis, which in most cases has S. aureus and S. agalactiae as causal agents, is an important disease in the livestock sector of Brazil due to losses it originates in the milk production chain and derivatives. In particular, S. aureus has a high zoonotic potential and is often associated as a cause of food poisoning outbreaks. Thus, controlling such microorganism in cows suffering from mastitis becomes crucial. However, this is an arduous task, since this bacteri ...

One of the main post-harvest problems is the emergence of spoilage in oranges caused especially by fungi that depreciate the quality and decrease shelf life and may also compromise food safety. Various treatment technologies such as: modified atmosphere, irradiation, anti-microbial ice and high pressure, among others, have been studied in the quest to eliminate food pathogens. Thus, understanding mechanisms of microorganism control in foods have been the topic of intense research with the use of

In Brazil, milk production is practiced by more than one million farmers, mostly smallholders, who have the most important sources of feed for the herd in pasture and forage grass cropping for cut-and-carry. One of the major demands of farmers is on improved forage cultivars for cutting and grazing that can meet the nutritional needs of herds throughout the year. Elephantgrass, in addition to its superior performance in the establishment of cut-and-carry plantations (i.e. green chopped, hay, and

Vaccination of animals as a method of controlling infectious diseases has been practiced for more than a century with remarkable success. The demand for more effective vaccines tends to grow as an alternative to the use of medicines and as a way to increase animal productivity, contribute to food safety and promote animal and human health. In addition, by minimizing the need for pharmacological interventions, the reduction of drug residues in the environment and in food is favored. As the use of

In recent decades, there has been a reduction in the consumption of some animal products due to the search for healthy products. In the case of dairy products, fat is an important source of conjugated linoleic acid (CLA), a set of bioactive isomers, some with beneficial effects for human health, for example, in the prevention of diseases such as Alzheimer's. The manipulation of ruminant diet has been the used alternative to change milk composition and, thus, producing CLA-rich milk products. Add

In recent years, there has been a tremendous advance in the frontier of knowledge in advanced biology. The impacts of this advance can be observed in the areas of molecular and cellular biology, with the mastery of gene engineering techniques, which led to the cloning of animal cells in the early 2000s, unprecedented in Brazil, and more recently to the emergence of new Areas of science, such as nanotechnology, epigenetics and genomics, among others. The project seeks to incorporate these advance

The emission increase of greenhouse effect gases and the high petroleum prices have elevated the demand for renewable fuels. For diesel, the most used fuel in the country, the main option has been the use of vegetable oil and animal fat by-products. However, there are two major problems regarding the production of vegetal oils which could hinder the use of these products as fuel: the quality and the quantity of oils produced. Of all the cultivated species, only the palm oil has the needed produc

Bovine mastitis is considered the main disease of dairy herds in the world, causing the greatest economic losses to the dairy sector. In Brazil, production losses caused by mastitis are estimated between 12 and 15%, accounting to more than three billion liters of milk per year. In addition, mastitis poses risks to public health, due to the possibility of contamination of milk with antibiotic residues or with microorganisms and their toxins. The high frequency of mastitis pathogens resistant to t
