Project description:Testing of response of hetertrophic partners (Halomonas sp. HL-48 and Marinobacter sp. HL-58) to both axenic and co-culture growth using both glucose and xylose
Project description:We have used a combination of constitutive and inducible MLL-AF4 and AF4-MLL fusion genes to investigate the power of theses fusion proteins. All transgenes were stably or transiently transfected. Here, we compared 48 induction of MLL-AF4 or AF4-MLL (day 3) and looked for persistance at days 28. This was compared to the situation with constitutive MLL-AF4 with 48 inductionn of AF4-MLL at day 3 and day 28.
Project description:This study aimed to characterize the non-targeted metabolite profile of Streptomyces sp. LZZY-S40 to explore its potential for producing bioactive secondary metabolites. The strain LZZY-S40 was cultivated on ISP 3 agar plates at 28°C for 7 days. Spores were harvested and inoculated into 250 mL Erlenmeyer flasks containing 50 mL of seed medium (pH 7.2–7.4) for 48 hours at 28°C with shaking at 250 rpm. The seed culture (8% v/v) was then transferred into fermentation medium and incubated under the same conditions for 7 days. After fermentation, the culture broth was centrifuged at 12,000 rpm for 10 minutes to separate the supernatant from the mycelial biomass. The supernatant was extracted three times with ethyl acetate, and the mycelial pellet was extracted with methanol. Organic extracts were concentrated under reduced pressure at temperatures below 40°C. The combined crude extracts were analyzed by untargeted liquid chromatography–mass spectrometry (LC–MS). Data were acquired in both positive and negative ionization modes across an m/z range of 50-1200, with chromatographic separation achieved using a gradient elution program at a flow rate of 400 μL/min and a column temperature of 40°C.
