This study was to examine the effects of yeast extract (YE) and its fractions (YE1 and YE2) on the growth and diepoxin ζ (a spirobisnaphthalene with a diversity of bioactivities) production in liquid culture of Berkleasmium-like endophytic fungus Dzf12 from Dioscorea zingiberensis. When YE was applied to the liquid medium at 10 g/L on day 3 of culture, the diepoxin ζ production was most effecti...

Yersinia heat-shock protein 60 (Ye-hsp60) has recently been found to be a dominant CD4 and CD8 T cell Ag in Yersinia-triggered reactive arthritis. The nature of this response with respect to the epitopes recognized and functional characteristics of the T cells is largely unknown. CD4+ T cell clones specific for Ye-hsp60 were raised from synovial fluid mononuclear cells from a patient with Yersi...

In this report, we describe the development and evaluation of a 5' nuclease PCR assay for the detection of pathogenic Yersinia enterocolitica (YE). The assay targets the chromosomally encoded invasion gene ail. Three different primer/probe sets (TM1, TM2, and TM3) amplifying different, yet overlapping, regions of ail were examined for their specificity and sensitivity. The TM1 set displayed the...

The influence of glucose and yeast extract (YE) as carbon and nitrogen sources, respectively, on the metabolic processes involving growth, insecticidal protein synthesis and sporulation were studied in batch bioreactor. Significant changes in the metabolic process were observed with different concentration level of glucose and YE. Higher concentration of glucose has resulted in heterogenous pop...

The objective of this study was to explore the trend and the epidemiological characteristics of malaria in Ningbo from 2000 through 2011 and provide scientific evidence for the prevention and control. Using the retrospective study, data relating to malaria epidemics during 2000-2011 in Ningbo were collected through the questionnaires of the cases and other important surveillance data. Adult mos...

Cogumelos do gênero Pleurotus são cultivados para fins alimentícios, medicinais e por serem fontes de enzimas interesse industrial. O presente estudo teve como objetivo avaliar o crescimento micelial verificar a atividade proteases P. djamor. Este cogumelo foi cultivado em ágar batata dextrose (BDA) com extrato levedura (YE) 0,5% (p/v). Para velocidade radial (VCR) densidade micelial, djamor ci...
