Abstract: Castor (Ricinus communis L.) oil is an important raw material for the chemical industry. The industrial process of castor oil extraction exposes the material to chemical, thermal, and mechanical treatments that influence the properties of the proteins in the meal. This study tested the hypothesis that the regular industrial process of castor oil extraction with solvent changes properties of the meal like the profile of proteins, the nematicide efficiency, and its toxicity. The changes made by the process of oil extraction create opportunities for adding value to this by-product. Samples of castor cake and meal were collected along the process of oil extraction under the regular operation of an industry. The samples were analyzed for chemical composition, hemagglutination activity, nematicide efficiency, and toxicity for feeding broilers and sheep. It was found that the step of solvent evaporation is responsible for the most relevant modifications in the meal, with significant changes in the protein profile, loss of hemagglutination capacity, and reduction of toxicity and nematicide efficiency. The castor meal produced just after the solvent evaporation has the toxicity reduced to a level that was tolerable to be used in the ration of small ruminants without detectable loss of performance or clinical signs of intoxication. The castor meal was toxic for broilers. The nematicide capacity of castor meal against larvae of Haemonchus contortus is reduced after the step of solvent extraction, but it is still significant and detected in doses as low as 5 mg/g. When castor meal was separated in fractions by sieving, the fine fraction (particles smaller than 0.5 mm) had high protein content (60.2%), low fiber content (6.0%), and high water holding capacity (164.2% of its dry weight).

Abstract: The increase on the worldwide influx of solar ultraviolet radiation (UV-B) has inflicted a considerable challenge, due to its deleterious effects to live beings and pose a special threat to phyllosphere communities. However, UV-B influence on epiphytic yeasts associated with agricultural crops remains limited. Main aim of the present study was to determine the effect of ultraviolet-B radiation on the epiphytic yeast populations associated with strawberry under field conditions. Thus, strawberries (Fragaria x ananassa Duchesne cv. Oso Grande) were grown under three different treatments: a) environmental UV-B, b) enhanced UV-B and c) decreased UV-B; thereafter, their yeast epiphytic populations were analyzed by T-RFLP prior to yeast isolation, identification and in vitro test for the sensitivity against UV-B. Our results demonstrated that UV-B radiation did not significantly affect the strawberry epiphytic yeast populations. However, isolates directly exposed to radiation, generally revealed morphological abnormalities and a diminishing value in the percentage of survival, although they remained constant after 240 min of exposure. The increase in UV-B radiation was not sufficient to affect the dynamics and composition of epiphytic yeast communities from strawberry, there was a clear morphotype shift towards the selection of pigmented isolates. |
