Table 2. Comparison between Conventional Extraction Performed on Raw Biomass and Biomass Post French Press Extraction and PLE Extraction after French Press in Terms of Extracted Carotenoids^a.

sample	carotenoid yield (mg/g_biomass)	carotenoid content (mg/g_extract)	zeaxanthin (mg/g_extract)	β-carotene (mg/g_extract)
raw biomass	62 ± 2	222 ± 24	2.7 ± 0.3	22 ± 4
post French press (conventional extraction)	100 ± 5^b	362 ± 24^b	33.4 ± 3.7^b	320 ± 76^b
post French press (PLE)	89 ± 6	911 ± 23^b^,^c	48±5^b^,^d	436 ± 60^e

Data shown are means ± S.D. of three independent experiments.

p < 0.05 with respect to raw biomass.

p < 0.005 with respect to conventional extraction after PC recovery.

p < 0.05 with respect to conventional extraction after PC recovery.
