1. Analysis of Water Barrier, Mechanical and Thermal Properties of Nanocoposites Based on Cassava Starch and Natural Clay or Modified by Anionic Exchange
Biopolymer films have several industrial applications because they are environmentally sustainable. Cassava starch is a biopolymer that is easily available, but has limitations: it is hydrophilic, poorly resistant and degradable. The improvement of these properties was proposed in this research from the use of bentonite clay (BT) as a filling material. The c

2. Protein co-products and by-products of the biodiesel industry for ruminants feeding
The objective of the experiment was to classify 20 protein co-products and by-products of the biodiesel industry with potential to use in ruminant feeding. The meals evaluated were: cottonseed, canudo-de-pito, crambe, sunflower, castor-oil seeds detoxified with calcium, non-detoxified castor-oil seeds and soybean; and the cakes were: cottonseed, peanut, baba

5. Characterization of biofilms produced from pea (Pisum sativum) starch associated with xanthan gum and glycerol / Caracterização de biofilmes obtidos a partir de amido de ervilha (Pisum sativum) associado à goma xantana e glicerol
In the past few years, the attempt to obtain degradable flexible packaging has increased considerably. In this sense, starches obtained from different botanical sources have been evaluated to produce films. Most of these films present good mechanical characteristics and provide a good barrier to oxygen. Nevertheless, some limitations have been observed in re

6. NUTRITIVE VALUE OF DIETS BASED ON FRESH RYEGRASS (Lolium multiflorum, LAM.) FORAGE SUPPLEMENTED WITH NITROGEN OR ENERGY / VALOR ALIMENTAR DE DIETAS COM AZEVÉM (Lolium multiflorum, LAM.) E SUPLEMENTAÇÃO NITROGENADA OU ENERGÉTICA
The present study was carried out to determine the effects of supplementing fresh ryegrass forage based diets with starch, rumen degradable or undegradable protein sources on intake, digestion and nitrogen retention, rumen digestibility and the duodenal nitrogen flow. Ten Corriedale lambs (26 kg mean body weight), kept in metabolic cages were used in a 5 x 5

7. Preparação, caracterização e degradação de blendas de poliestireno e amido termoplástico usando glicerol e óleo de buriti (Mauritia flexuosa) como plastificantes
The great amount of synthetic plastics that are discarded in the environment causes pollution because they are inert against the attack of microorganisms. This fact leads the researches to development biodegradable polymers. Polystyrene (PS) is among the most dominant packaging materials nowadays, however it does not decompose itself. Addition of cassava sta

8. In vitro degradation dynamics of neutral detergent fiber of signal grass according to supplementation with different sources of nitrogenous compounds and carbohydrates / Dinâmica de degradação in vitro da fibra em detergente neutro de capim-braquiária em função de suplementação com diferentes fontes de compostos nitrogenados e carboidratos
Two experiments were carried out to evaluate the utilization of fibrous carbohydrates from high quality grass by ruminal microorganisms. In the first experiment, it was studied the degradation dynamics of neutral detergent fiber (NDF) from high quality signal grass (Brachiaria decumbens Stapf.) according to supplementation with different sources of carbohydr

9. Dinâmica de degradação in vitro da fibra em detergente neutro de forragens tropicais em função de suplementação protéica e/ou energética / In vitro degradation dynamics of tropical forages neutral detergent fiber according to protein and/or energy supplementation
The current thesis was based on two in vitro trials aiming at assessing the effect of protein and/or energy supplementation on ruminal degradation of fibrous carbohydrates of tropical forages. At Experiment 1, it was evaluated the effect of protein and/or energy supplementation on the utilization of fibrous carbohydrates from low quality forage by ruminal mi

10. Estudo e desenvolvimento de compositos de polietileno de baixa intensidade (PEBD) com amido, parcialmente degradaveis no meio ambiente
The large amount of plastic waste in the environment has stimulated several important researchers to develop new products and processes that preserve the environment without blocking the growing consumption of these materials. Among several good alternatives as incineration, recycling and pyrolysis, the production of environmentally degradable polymers (EDPs

11. Degradation of Degradable Starch-Polyethylene Plastics in a Compost Environment †
The degradation performance of 11 types of commercially produced degradable starch-polyethylene plastic compost bags was evaluated in municipal yard waste compost sites at Iowa State University (Ames) and in Carroll, Dubuque, and Grinnell, Iowa. Masterbatches for plastic production were provided by Archer Daniels Midland Co. (Decatur, Ill.), St. Lawrence Sta

12. Production of an extracellular polyethylene-degrading enzyme(s) by Streptomyces species.
Extracellular culture concentrates were prepared from Streptomyces viridosporus T7A, Streptomyces badius 252, and Streptomyces setonii 75Vi2 shake flask cultures. Ten-day-heat-treated (70 degrees C) starch-polyethylene degradable plastic films were incubated with shaking with active or inactive enzyme for 3 weeks (37 degrees C). Active enzyme illustrated cha
