BNC production rates and yields utilizing the three media supplemented with the date, fig, and molasses substrates comparing to yield on (HS) medium by K. saccharivorans MD1 after incubation for 168 h.

Medium	Si (g/L)	M (g/L)	∆S (g/L)	α (%)	Y (%)	R (g/L.h)
HS	20	2.6	17.8	89	14.6	0.01
D-HS	56	3.2	44.6	79	5.7	0.019
F-HS	14	1.1	10.3	73	7.8	0.006
M-HS	62	3.9	57	91	6.2	0.02

(Si) Initial substrate concentration; (M) amount of BNC produced; (∆S) amount of the consumed substrate; (α) substrate conversion ratio; (Y) BNC production yield; (R) BNC production rate or productivity.
