Bacteria and yeasts associated to Colonial cheese production chain and assessment of their hydrolytic potential

Abstract: Different types of microorganisms are important in cheese-making because of the contributions their metabolism offers during the process. Few microorganisms present in Colonial cheese are known, in addition to the ones that are introduced to kick-start the processes or the ones that are associated with infections or poisonings. This study aimed to identify, by MALDI-TOF and/or DNA sequencing, the bacteria and yeasts isolated from samples collected in the main stages of Colonial cheese production, i.e., a type of cheese produced in the southern region of Brazil. The lytic capacity of these microorganisms at 5 °C and 30 °C was also evaluated. The 58 bacterial strains were distributed in 10 species among the genera Bacillus, Citrobacter, Klebsiella, Lactococcus, Paenibacillus, Staphylococcus and Raoutella. From the 13 yeasts strains analyzed, three species were identified as following: Candida pararugosa; Meyerozyma guilliermondii; and Rhodotorula mucilaginosa. In three yeasts isolates it was possible to identify only the genus Candida sp. and Trichosporon sp. The species L. lactis (48%) and M. guilliermondii (46%) were, respectively, the predominant bacteria and yeasts species isolated. The highest microbial lytic activity observed was at 30 °C. Lipase activity on isolates was proportionally more observed with yeasts and proteolytic activity with bacteria. Lower caseinase and lipase activity was observed at 5 °C, demonstrating the importance of refrigeration in controlling microbial activity. This research highlighted the cultivation of some microorganisms that are part of the Colonial cheese microbiota as well as that several of them can hydrolyze various compounds present in milk and that could be associated with its maturation or, in uncontrolled circumstances, could be the cause of product deterioration.

Desempenho de coelhos em crescimento recebendo dietas com suplementação enzimática

Abstract: The objective of this work was to evaluate the weight gain, feed intake, feed conversion, carcass weight and carcass yield of rabbits fed on diets supplemented with increasing levels of an enzyme complex (Vegproâ) of protease and cellulase activities. Seventy-five New Zealand White rabbits were weaned by 40 days of age, being separated at random into 5 treatments, according to the level of enzyme supplementation: A-0.,00; B-0.05; C-0.10; D-0.15 and 0.20%. No significant difference (P<0.05) was observed among treatments for feed intake and daily gain. For feed conversion the only significant (P<0,05) difference was between control and treatment B. Carcass weight were significantly (P<0.05) heavier for animal under diet B (0.05% enzimatic complex) whereas carcass yield did not experience any enzimatic effect.

Sandfly fauna and behavior (Diptera: Psychodidae) in municipalities of the Mesoregion North Pioneer of Paraná, Brazil

Abstract: The occurrence of cutaneous leishmaniasis (CL) in the municipalities of Jaboti, Japira, Pinhalao, and Tomazina in the North Pioneer of the State of Parana, where this disease is endemic, prompted the investigation of sandfly fauna, their population changes throughout the year, and their behavior in and around human accommodation. In these municipalities, the collection of sandflies was conducted using Falcao traps from 7 pm to 6 am once a month. 32,994 sandflies, 18,442 males and 14,552 females, were collected and represented by the species Brumptomyia brumpti, Brumptomyia cunhai, Evandromyia correalimai, Evandromyia cortelezzii, Expapillata firmatoi, Micropygomyia ferreirana, Migonemyia migonei, Nyssomyia neivai, Nyssomyia whitmani, Pintomyia fischeri, Pintomyia monticola, Pintomyia pessoai, and Psathyromyia bigeniculata. Ny. neivai (SISA = 0.9808) predominated in Japira (46.9%), Pinhalao (53.1%), and Tomazina (38.9%), while Ny. whitmani (SISA = 0.9423) predominated in Jaboti (53.8%). Most sandflies were captured in domestic animal shelters, with a peak in September. The high number of sandflies collected in domestic animal shelters, species richness, and presence of species involved in the epidemiology of CL reveal the need for permanent entomological surveillance in the municipalities mentioned. The use of phlebotomine control measures in these municipalities should be considered in conjunction with the anthropogenic actions that have resulted in changes to sandfly fauna and behavior.
