| The microbial protein bioconversion of cactus pear by yeast in solid medium was studied. Three cultivation variables used were: inoculum's concentrations (5, 10 and 15 %), substrate layer thickness (2, 4 and 6 cm) and temperature (30, 34 and 38 ºC). The rate of dry matter production and total protein were determined. Results obtained were variance analysis, gross energy and in vitro dry matter digestibility. The maximum protein amount achieved for the conditions studied in the present work was higher than 26 %, which was compatible or greater than those of conventional concentrates of protein supplements used for animal feed. The protein concentrate of cactus pear had a higher in vitro digestibility index (95.8 %) and did not show any changes in the gross... |

| Soybean plants cultivated with 50, 100 and 200 mM of NaCl, revealed that root growth was less affected by salinity than shoots. Salinity led to a reduction in leaf area and an increase in water content of the roots. These factors could contribute to the adaptation of the plant, improving its hydration. Although nitrate and free amino acid levels were reduced by salt treatment in roots, protein content of leaves was not altered. Salinity led to alterations in xylem amino acid composition, with increases in Ser, Ala, Gaba and Pro and a decrease in Asn. Similar changes were seen for Asn and Ser in roots together with a much stronger increase in Gaba. It is suggested that the decline in Asn reflects its conversion to Ala and Gaba (via Glu) in the roots while... |

| Ulomoides dermestoides (Fairmaire, 1893) develops in stored food products (peanuts, maize, oats, rice, sorghum, etc.) and breeds successfully in the laboratory. To determine the best conditions for development, experiments were set up in different temperatures and diets, similar to storage conditions of peanuts (Arachis hypogaea L.). The higher viability of individuals and the shorter developmental time were observed in the diet composed of hulls and seeds of fruits at 21 and 24°C. |

| The proximate chemical composition of hump, known in Brazil as cupim, Rhomboideus m. (RB), of Nelore (Bos indicus) aged 24 months revealed it to be a unique beef muscle. It presents a lipid fraction 14-fold as high as that of Longissimus dorsi m. (LD) taken from the same animal (p<0.05), the highest value reported so far. This was unequivocally observed by the histological evaluation. Proportionally more protein fraction and conversely less moisture were also observed in RB. Analysis of collagen and its crosslinking with hydroxylysylpyridinium (HP) showed there to be 22.9% more collagen and 14-fold as much HP in RB as in LD. Contrary to the expectations, the tenderness of fresh samples evaluated by Warner Bratzler shear force measurements led to values... |

| ABSTRACT The rhizosphere zone has been defined as the volume of soil directly influenced by the presence of living plant roots or soil compartment influenced by the root. During the growing season of 2014, the rhizobacteria of 23 sugar beet plants sampled from 12 sites in the west and north west of Iran were inventoried. Using a cultivation-dependent approach, a total of 217 bacteria were isolated from the rhizosphere. The bacterial isolates were tentatively grouped and documented based on polyacrylamide gel electrophoresis of whole-cell proteins and were found to represent 43 different protein electrotypes. The majority of the fingerprint types were found only on a single occasion. Fifty-nine percent of the strains belonged to the five bacterial species... |

| The effects of volatile organic compounds (VOCs) on methane oxidation in landfill cover soils were examined. The batch experiments were conducted using single and mixed VOCs, such as, dichloromethane (DCM), trichloroethylene (TCE), tetrachloroethylene (PCE), and benzene. The results from all combinations showed a decrease in methane oxidation rate with increase in VOC concentrations. Moreover, inhibition effects of TCE and DCM were found higher than benzene and PCE. The reduction of methane oxidation by benzene and PCE could be attributed to the toxicity effect, whereas TCE and DCM were found to exhibit the competitive-inhibition effect. When the soil was mixed with DCM, no methane oxidation was found. Damage to the cells internal membrane was found in a... |

| ABSTRACT This study evaluates the potential of rubber tree clones (Hevea spp.) under four tapping systems for the Northwestern region of the State of Paraná with the objective of enhance genetic diversification and increase natural rubber production in this new and promising region for rubber tree cultivation by selecting the better combination of clone and tapping system. The experiment was installed at Guanabara Farm, municipality of Paranapoema, Paraná State, in a split-plot randomized complete blocks experimental design with three replications. In the plots 12 clones were tested, namely RRIM 600 (control), IRCA 18, IRCA 111, IRCA 130, PB 235, PB 252, PB 260, PB 330, IAC 15, IAC 35, IAC 41 and RO 38. The subplot treatments consisted of four tapping... |
