Eicosapentaenoic acid production from Nannochloropsis oceanica Cy2 using deep sea water in outdoor plastic-bag type photobioreactors
Bioresour Technol 2018 Apr;253:1-7.PMID:29328929DOI:10.1016/j.biortech.2017.12.102.
In this study, Nannochloropsis oceanica Cy2 was grown in deep-sea water (DSW)-based medium in 5-L plastic bag-type photobioreactors (PBRs) for the autotrophic production of Eicosapentaenoic acid (EPA, 20:5n-3). EPA production of N. oceanica Cy2 was stimulated when it was grown in 100% DSW amended with 1.5 g L-1 NaNO3, achieving a EPA content of 3.1% and a biomass concentration of 3.3 g L-1. An outdoor-simulated microalgae cultivation system was also conducted to validate the feasibility of outdoor cultivation of the Cy2 strain in plastic bag-type PBRs. Using an inoculum size of 0.6 g/L, the biomass concentration in the PBR culture was 3.5 g L-1, while the EPA content and productivity reached a maximal level of 4.12% and 7.49 mg L-1 d-1, respectively. When the PBRs were operated on semi-batch mode, the EPA productivity could further increase to 9.9 mg L-1 d-1 with a stable EPA content of 4.1%.
Toxicity of busulfan and cyclophosphamide (BU/Cy2) in patients with hematologic malignancies
Bone Marrow Transplant 1996 Mar;17(3):329-33.PMID:8704682doi
Between July 1991 and January 1994, 52 patients with hematologic malignancies underwent BMT using BU/Cy2 as conditioning regimen. Median patient age was 38 years. Eleven patients underwent autologous BMT, 22 HLA-identical allogeneic BMT, and 19 patients underwent a MUD or an allogeneic mismatched BMT. GVHD prophylaxis was with cyclosporine/methylprednisone in 26 patients; T cell depletion was used in 15 patients. VOD was observed in 7.5% of patients, IP in 12%, seizures in 4%. The overall incidence of grade II-IV acute GVHD was 35%. Delayed platelet engraftment was observed in seven of 11 patients who underwent autologous BMT. Graft failure was seen in seven of 19 (37%) patients who underwent MUD or allogeneic mismatched BMT. Six of the seven patients received T cell depletion as GVHD prophylaxis. BU/Cy2 transplantation from an unrelated or family-mismatched donor with T cell depletion is associated with a high incidence of graft failure.
Busulfan and cyclophosphamide (BU/Cy2) as preparative regimen for patients with lymphoma
Bone Marrow Transplant 1997 Apr;19(8):777-81.PMID:9134168DOI:10.1038/sj.bmt.1700733.
The combination of busulfan and cyclophosphamide has seldom been employed as a conditioning regimen for patients with lymphoma. Twenty patients with relapsed or refractory lymphoma were treated with busulfan (16 mg/kg) and cyclophosphamide (120 mg/kg) (BU/CY) followed by peripheral blood stem cell rescue in 19 patients or autologous bone marrow in one patient. There were 12 females and eight males, with a median age of 48 years (range 30-65). Four patients had Hodgkin's disease, and 16 patients had non-Hodgkin's lymphoma. Disease status at the time of BU/CY was: first relapse in 10 patients (four patients with chemosensitive disease and six patients with chemoresistant disease), primary refractory disease in six patients, and more advanced disease in four patients. Excessive treatment-related toxicity was not noted. There were no cases of interstitial pneumonitis, but three cases of veno-occlusive disease occurred. At 2 years, the estimated overall survival and event-free survival are 50% and 33%. We concluded that BU/CY seems to have sufficient antilymphoma activity, is devoid of excessive toxicity and warrants further investigation in this patient population.
Engineering strategies for enhancing the production of eicosapentaenoic acid (EPA) from an isolated microalga Nannochloropsis oceanica Cy2
Bioresour Technol 2013 Nov;147:160-167.PMID:23994697DOI:10.1016/j.biortech.2013.08.051.
Microalgae have emerged as promising resources for highly unsaturated fatty acids. In this study, an indigenous microalga identified as Nannochloropsis oceanica Cy2 was grown photoautotrophically to produce eicosapentaenoic acid (EPA; 20:5, n-3). Specific engineering strategies were employed to stimulate EPA accumulation in the microalgal cells. The results show that BG-11 was the most effective medium to grow N. oceanica Cy2, giving an EPA content and biomass concentration of 2.38% (per dry cell weight) and 1.53 g/l. The EPA content nearly doubled when using the optimal nitrogen source (NaNO3) at a concentration of 1.50 g/l. The illumination system also markedly affected the EPA content for the photoautotrophic microalga. When the microalgal culture was illuminated with a red LED, an impressively high EPA content of 5.5% was obtained. Finally, using semi-batch cultures operations with LED-blue illumination, the EPA content of N. oceanica Cy2 was stably maintained at 5.0%.
Enhancing the production of eicosapentaenoic acid (EPA) from Nannochloropsis oceanica Cy2 using innovative photobioreactors with optimal light source arrangements
Bioresour Technol 2015 Sep;191:407-13.PMID:25777066DOI:10.1016/j.biortech.2015.03.001.
Binary combinations of LEDs with four different colors were used as light sources to identify the effects of multiple wavelengths on the production of eicosapentaenoic acid (EPA) by an isolated microalga Nannochloropsis oceanica Cy2. Combining LED-Blue and LED-Red could give the highest EPA productivity of 13.24 mg L(-1) d(-1), which was further enhanced to 14.4 mg L(-1) d(-1) when using semi-batch operations at a 40% medium replacement ratio. A novel photobioreactor with additional immersed light sources improved light penetration efficiency and led to an 38% (0.170-0.235 g L(-1) d(-1)) increase in the microalgae biomass productivity and a 9% decrease in electricity consumption yield of EPA (10.15-9.33 kW-h (g EPA)(-1)) when compared with the control (i.e., without immersed light sources). Operating the immersed LEDs at a flashing-frequency of 9 Hz further lowered the energy consumption yield to 8.87 kW-h (g EPA)(-1).
