Microbial synthesis of valuable hemoproteins has become a popular research topic, and Pichia pastoris is versatile platform for the industrial production recombinant proteins. However, inadequate supply heme limits high-active hemoproteins. Here strategy enhancing intracellular biosynthesis to improve titers functional activities reported. After selecting suitable expressional globins, efficient heme-supply P. chassis established by removing spatial segregation during biosynthesis,...

To improve the screening efficiency of high-yield neomycin sulfate (NM) Streptomyces fradiae strains after mutagenesis, a high-throughput method using streptomycin resistance prescreening (8 μg/mL) and 24-deep well plates/microplate reader (trypan blue spectrophotometry) rescreening strategy was developed. Using this approach, we identified high-producing NM mutant strain, Sf6-2, via six rounds atmospheric room temperature plasma (ARTP) mutagenesis screening. The displayed potency 7780 ± 110...

Background Plesiomonas shigelloides can cause gastroenteritis and extra-intestinal diseases in humans. However, the prevalence of P. infections has not been investigated China. Methods Consecutive fecal specimens from outpatients with acute diarrhea non-diarrheal patients at nine sentinel hospitals southeast China were collected March 2010 to May 2012. Bacterial pathogens detected by culture, isolates subjected antimicrobial susceptibility testing. We also retrospectively reviewed hospital...

Ganoderic acids (GAs), derived from the medicinal mushroom Ganoderma lucidum, possess anticancer and other important pharmacological activities. To improve production of GAs, a homologous farnesyl diphosphate synthase (FPS) gene was overexpressed in G. lucidum. Moreover, influence FPS overexpression on GA investigated by developing corresponding mathematical models.The maximum levels total GAs individual (GA-T, GA-S, GA-Me) transgenic strain were 2.76 mg/100 mg dry weight (DW), 41 ± 2, 21 5,...

Acute diarrhea is an important public health issue. Here, we focused on the differences of enteropathogens in acute between urban and rural areas southeast China. Laboratory- sentinel-based surveillance (≥ 3 loose or liquid stools/24 hours) was conducted at 16 hospitals. Fecal specimens were tested for bacterial (Aeromonas sp., Campylobacter diarrheagenic Escherichia coli, Plesiomonas shigelloides, non-typhoidal Salmonella, Shigella Vibrio Yersinia sp.) viral (adenovirus, astrovirus,...

In China, V. parahaemolyticus has been a leading cause of foodborne outbreaks and bacterial infectious diarrhea since the 1990s, most infections have associated with pandemic O3:K6 its serovariants. However, comprehensive overview sero-prevalence genetic diversity clone in China is lacking. To compensate for this deficiency, isolates both clinical environmental Chinese samples collected from multiple studies were analyzed study. Surprisingly, as many 27 serovariants identified widely...
