1. Soil Fertility and Electrical Conductivity Affected by Organic Waste Rates and Nutrient Inputs
ABSTRACT The composition of organic waste (OW) and its effect on soil processes may change soil fertility and electrical conductivity (EC). The side effects of waste use in crop fertilization are poorly understood for Brazilian soils. This study examined the effect of the addition of 15 different organic wastes to Oxisols and a Neosol on pH, base saturation,

2. Characterization of Metallurgical Coke Produced with Coal Mixtures and Waste Tires
The use of scrap tires in the coal blends is an alternative to reduction of coke production costs as well as mitigates the impact caused by tire accumulation in the environment. Tests were carried out on a pilot scale, with coal blends and waste tire in 4 levels and 3 particle sizes, in order to assess the impact on the produced coke quality, especially on t

3. Linear Programming in the economic estimate of livestock-crop integration: application to a Brazilian dairy farm
ABSTRACT A linear programming mathematical model was applied to a representative dairy farm located in Brazil. The results showed that optimization models are relevant tools to assist in the planning and management of agricultural production, as well as to assist in estimating potential gains from the use of integrated systems. Diversification was a necessar

4. The use of date waste for lactic acid production by a fed-batch culture using
Lactobacillus casei subsp.rhamnosus The production of lactic acid from date juice by
Lactobacillus casei subsp.rhamnosus in batch and fed-batch cultures has been investigated. The fed-batch culture system gave better results for lactic acid production and volumetric productivity. The aim of this work is to determine the effects of the feeding rate and the cBraz. J. Microbiol.. Publicado em: 21/07/2015

5. Kinetics of transit and degradation of the fiber from guinea grass silages enriched with waste from soybean pre-cleaning
The objective was to study the kinetics of transit and degradation of the fiber from guinea grass and the waste from soybean pre-cleaning (WSPC), ensiled with different proportions of mass (0, 100, 150, and 200 g WSPC/kg total mass). Four crossbred (Gyr × Holstein), fistulated cattle with an average body mass of 400±50 kg were organized in a 4 × 4 Latin s

7. Produção de bioetanol a partir de resíduos agroindustriais
Concerns about global warming and the depletion of petroleum cause the search for alternative fuels from renewable sources. The current study aims at obtaining bioethanol from fermentable sugars extracted from hydrolyzed residues in situ by solid-state fermentation (SSF). The first stage was the SSF for the hydrolysis of the culture medium which is composed

8. Destilado da desodorização do oleo de soja como suplemento de vitamina E / Soybean oil deodorizer distillate as a vitamin E supplement
Increased use of industrial waste and byproducts fits the need of industry to comply with environmental rules. The substitution of natural products for artificial ingredients has gained worldwide attention in the food, pharmaceutical and other industries. These facts justify the study on the utilization of Soybean Oil Deodorizer Distillate (SODD) as tocopher
