Effect of in situ addition of different types of anion exchange resins (10 gL^-1) on the performance of P. acidilactici in batch fermentation.

Type of resin	Maximum viable cell concentration (cfu mL^-1)	Lactic acid accumulated (gL^-1)
IRA 67	1.3 × 10¹¹± 0.04^a	4.74 ± 0.03^e
IRA 410	1.0 × 10¹¹± 0.07^c	5.63 ± 0.12^c
Duolite A7	1.1 × 10¹¹ ± 0.06^b	5.41 ± 0.03^d
IRA 400	1.0 × 10¹¹± 0.11^c	5.58 ± 0.07^c
Dowex MSA	1.4 × 10¹⁰ ± 0.07^d	5.92 ± 0.06^b
Control	1.1 × 10¹⁰± 0.04^e	7.64 ± 0.02^a

The results of maximum viable cell concentration and concentration of lactic acid accumulated are the average of triplicate experiments. a, b, c, d, and e: Mean values with the different letters are significantly different. Statistically significant coefficient (P < 0.05) are expressed as means ± SE.
