Raw data of a set of experiments aimed to evaluate the influence of hydrophilic carbon and nitrogen sources on the production of deacetylated lactonic C18:1 sophorolipid focusing on the variation of glucose and urea ratio by applying a Box-Behnken design (BBD)

METHODOLOGICAL INFORMATION

Experimental design carried out with a solid matrix made up wheat straw, winterization oil cake, nutrient’s dilution mix (glucose, yeast extract and urea) and Starmerella bombicola yeast.

1. Description of methods used for collection-generation of data: Several solid-state fermentations at Erlenmeyer flask scale (0.5L) with a total solid substrate weight around 20.3 ± 0.6 g with a dry matter of 53.5% (10.84 g).

2. Methods for processing the data: Production, productivity and growth results were analized based on a quadratic model. Growth results were transform in log for a better fitting.

3. Instrument- or software- specific information needed to interpret the data:

4. Excel or similar soft

5. Design Expert 12® program (Stat-Ease, Inc, United States)

6. Instruments, calibration and standards information:

7. Balanza Analítica Sartorius Entris II
8. Gitateur incubateur orbital refrigere NB-205LF
9. Incubador IN750 Memmert 749 litros
10. HPLC UltiMateTM 3000

11. NucleosylTM 100 x 3 x 4.6 mm C18 EC

12. Environmental or experimental conditions:

13. Seed Starmerella bombicola ATCC 22214

14. Solid state fermentation developed at 30 ºC, at 96, 168 and 240h.

15. Quality-assurance procedures performed on the data: A triplicate was set up in the central point for each fermentation time and residues subtitution was performed by triplicate and dupplicate for pure error estimation.
