The stirring speed required for the culture of kefir grains was studied, to optimize its growth in a culture medium of molasses and whey. The results show that this mixture of microorganisms requires stirring to optimize its growth and can grow in a wide range of stirring speeds, from laminar flow, with Reynolds number lower than 2000, to turbulent flow with Reynolds number greater than 3500. This shows that the culture of kéfir grains, can adapt to different stirring speeds, making its culture very easy with respect to this variable

Were evaluated the varieties yellow, white and purple of the species Arracacia xanthorrhiza “Arracacha”, , coming from Socota district of Cutervo province in department of Cajamarca, supplied for the “Instituto Nacional de Investigación Agraria” (INIA). Also are well-known like r’acacha, laqachu, rakkacha, virracacha, ricacha, arracacha, racacha, arrecate, zanahoria blanca, apio criollo, sonarca, virraca, zanahoria del país, zanahoria morada. They are consumed in greater percentage like fresh product and their stems to tier to us are used in salads or like vegetables cooked or mixed with other roots. They presents content of water of 71,34 to 73,86 grams percent. In dry sample: total protein 2,10 to 2,65; ash 2,26 to 2,81; ethereal extract 0,91 to 0,98; raw fiber 3,25 to 3,38; carbohydrates from 86,67 to 86,91; total reducing sugars 2,65 to 3,94 and caloric value of 363,40 to...

In this study, was investigated the antistaphylococcal activity in vitro of ethanol and hydroalcoholic extracts of 3 peruvian medicinal plants: Juglans neotropica Diels (bark), Piper lineatum Ruiz & Pav. (leaves) and Terminalia catappa L. (leaves). The species were collected in the regions of Amazonas and Cajamarca, in Peru. Antistaphylococcal activity was assessed by microdilution method. The organisms used were bacteria Staphylococcus aureus ATCC 25923 and Staphylococcus epidermidis ATCC 12228. All extracts investigated showed significant activity against both bacteria with a minimum inhibitory concentration (MIC) of 125 to 500 μg/mL for Staphylococcus aureus, with increased activity of the ethanol extract of Juglans neotropica Diels, and of 250 to 500 μg/mL for Staphylococcus epidermidis, having greater activity the hydroalcoholic extract of Piper lineatum Ruiz & Pav.
