Oxidatively Stable saturated Fatty Acid Containing Oil
The invention relates to an oil comprising one or more polyunsaturated fatty acids having
at least 4 double bonds.
CROSS—REFERENCE TO RELATED APPLICATIONS
This application claims the benefit under 35 U.S.C. §l 19(e) to US. Provisional
Application No. 61/554,291, filed November I, 2011, 2
Oils ning polyunsaturated fatty acids ) may oxidize and become rancid
during e. This results in unpleasant flavors and odors in the oil as well as in the products
in which such oils are incorporated. A PUFA with 4 or more C-C double bonds may be less
oxidatively stable than a PUFA with fewer double bonds. Moreover, the presence of metals,
such as, iron, may increase the rate at which a PUFA containing oil oxidizes.
Those skilled in the art have attempted to decrease the oxidation of a PUFA containing
oil by employing various means including incorporating ascorbic acid derivatives, such as,
ascorbyl palmitate in combination with lecithin. There, however, s a need for more
oxidatively stable PUFA containing oils.
It has now been discovered that ing ascorbic acid derivatives, such as, ascorbyl
palmitate with lecithin increases the ion of an oil comprising 30% of at least one PUFA
having 4 or more carbon-carbon double bonds. Accordingly, the following non-limiting
embodiments of the present invention are provided herein. The embodiments described herein
may be suitably combined or subdivided to yield suitable subcombinations to comprise, t
of or consist essentially of additional embodiments

EXAMPLE 2
Fatty Acid Profile of PTA-10208. Two samples of the biomass produced in accordance
with Example 1 (PTA-10208 Sample #1 and PTA-10208 Sample #2) were analyzed for total
crude oil content by solvent extraction, lipid s were determined by high performance liquid
chromatography/evaporative light scattering detection (HPLC/ELSD), triacyl ol (TAG) was
analyzed by HPLC/mass spectrometry MS), and fatty acid (FA) profiles were determined
by gas chromatography with flame tion detection (GC-FID). The crude lipid content of
each freeze dried biomass was determined using solvent grinding with hexane and compared to
the sum of FAME (mg/g) generated by direct transesterification, and the resultant fatty acid
methyl esters (FAME) were quantified by GC/FID is. FAs in the extracted crude lipid
were also quantified by transesterification and quantified using GC/FID analysis of the ant
FAME. The weight percent of all neutral lipids (NL) and free fatty acids (FFA) were determined
in the extracted crude lipid using normal phase HPLC with ELSD and atmospheric pressure
chemical ionization-MS MS) identification. The method separates and quantifies sterol
esters (SE), TAG, FFAs, 1,3-diacylglycerols (1,3—DAG), s, 1,2-diacylglycerols (1,2-DAG),
and monoacylglycerols (MAG). Results are shown in Tables 2 and 3.
The TAG and phospholipids (PL) were isolated from the extracted crude oil
(PTA-10208 Sample #1 and PTA-10208 Sample #2). TAG was isolated using low pressure flash
chromatography and PL was isolated using solid phase extraction (SPE). The identity of each
isolated fraction was confirmed by thin layer chromatography (TLC). The fatty acid profiles of
the isolated TAG and PL fractions were determined ing direct transesterification using
GC-FID as FAME. Results are shown in Table 4.
dual lipid classes were isolated from a sample of crude oil extracted from
PTA-10208'(PTA-10208 Sample #3) using normal HPLC with ELSD and APCI—MS
identification.
Experimental Procedures.
Crude Oil Extraction — Crude oil was extracted from samples of freeze-dried biomass
using solvent grinding. For example, approximately 3 grams of biomass was weighed into a
Swedish tube. Three ball gs and 30 mL of hexane were added to the Swedish tube, which
was sealed with a neoprene stopper and placed in a shaker for 2 hours. The resultant slurry was
filtered using a Buchner funnel and Whatman filter paper. The filtered liquid was collected, the
t removed under vacuum, and the amount of remaining crude lipid determined
gravimetrically. .
Fatty Acid is — The s of biomass, ted crude lipid, and isolated lipid
classes were analyzed for fatty acid composition as FAME. Briefly, freeze-dried biomass and
isolated lipid classes were weighed directly into a screw cap test tubes, while s of the
crude oil were dissolved in hexane to give a concentration of approximately 2 mg/mL. Toluene,
containing internal standard, and 1.5 N HCl in methanol was added to each tube. The tubes were
vortexed, then capped and heated to 100° C for 2 hours. The tubes were allowed to cool, and
saturated NaCl in water was added. The tubes were vortexed again and centrifuged to allow the
layers to separate. A portion of the organic layer was then placed‘in a GC vial and analyzed by
GC-FID. FAME was quantified using a 3-point calibration curve generated using Nu-Check-
Prep GLC Reference Standard-(NuCheck, Elysian, MN). Fatty acids present in the extract were
expressed as mg/g and as a weight percent. Fat content in the samples was estimated assuming
equal response to the internal standard when analyzed by GC-FID.

Solid Phase tion ~PL fractions were separated from the crude lipid by solid phase
extraction (SPE) using 2 g aminopropyl cartridges (Biotage, Uppsala, Sweden) placed in a Vac
Elut apparatus (Varian Inc, Palo Alto, USA). The cartridge was conditioned with 15 mL of
hexane, and ~60 mg of each was dissolved in 1 mL CHC13 and applied to the cartridge.
The column was washed with 15 mL of 2:1 CHCl3zisopropyl alcohol to elute all the neutral
lipids, which was discarded. The fatty acids were then eluted with 15 mL of 2% acetic acid
(HOAc) in ether, which was discarded. The PL portion was eluted with 15 mL of 6:1
MethanolzChloroform, which was collected, dried under nitrogen, and weighed.
Flash Chromatography — Flash chromatography was used to separate the lipid classes
present in the crude oil. Approximately 200 mg of crude oil dissolved in hexane was ed
onto the head of the column. The chromatography system utilized Silica Gel 60 (EMD
Chemical, own, NJ) with mobile phase composed of Petroleum Ether and Ethyl Acetate at
mL/min (Tables 6—7) or 3 mL/min (Tables 8-13). A step gradient was used to selectively elute
each lipid class from the column. The mobile phase gradient started from 100% petroleum ether
and finished with 50% ethyl acetate. Fractions were collected in 10 mL test tubes using a Gilson
FC 204 large-bed fraction collector (Gilson, Inc., Middleton, WI). Each tube was analyzed by
thin layer tography (TLC) and the tubes containing individual lipid classes (as judged by
single spots on TLC plate with expected retention factor (Rf)) were pooled, concentrated to
dryness, and d. The total fraction content was then ined gravimetrically.
TLC Analysis — Thin layer chromatography was conducted on silica gel plates. The plates
were eluted using a t system consisting of petroleum etherzethyl etherzacetic acid (80:20: 1)
and were visualized using iodine vapor. The Rf values of each spot were then compared with
reported literature values for each lipid class.
Analysis ofTAG and PLfractions — The isolated TAG and PL fractions were analyzed
for fatty acid composition as fatty acid methyl esters (FAME). The TAG fractions were
dissolved in hexane to give a concentration of approximately 1-2 mg/mL. 1 mL aliquots of the
solutions were trated to dryness under nitrogen. Toluene, containing internal rd,
and 1.5 N HCI in methanol was added to each tube. The tubes were vortexed, then capped and
heated to 100° C for 2 hours. lntemal standard and HCl ol were added directly to the
tubes containing the PL fraction and heated. The tubes were allowed to cool, and saturated NaCl
in water was added. The tubes were vortexed again and centrifuged to allow the layers to
separate. A n ofthe organic layer was then placed in a GC vial and analyzed by GC-FID.
FAMEs were quantified using a 3-point calibration curve generated using Nu-Check-Prep GLC
5028 Reference Standard (NuCheck, Elysian, MN). Fatty acids present in the extract were
. sed as mg/g and as a % of FAME.
PTA-10208 Sample #1. The‘fatty acid profile of the biomass and extracted crude lipid
for PTA-10208 Sample #1 was determined using GC/FID. FAs in the biomass were
transesterified in situ by weighing 28.6 mg of biomass directly into a FAME tube, while a
sample ofthe extracted crude lipid was ed by weighing 55.0 mg of crude lipid into a 50
mL volumetric flask and transferring 1 ml to a separate FAME tube. The estimated crude lipid
content ofthe biomass was determined to be 53.2% (as SUM of FAME) using GC with FID
detection, while 52.0% (wt/wt) lipid was extracted from the dry s, giving a 97.8%
recovery of total lipid. The crude lipid was determined to be 91.9% fatty acids (as SUM of
FAME) using GC/FID. The major fatty acids contained in the crude lipid were C1620 (182.5
mg/g), C20:5 n-3 (186.8 mg/g), and C2226 n-3 (423.1 mg/g).
The lipid class profile of the extracted crude lipid was determined by weighing 55.0 mg
of crude lipid into a 50 mL volumetric flask and transferring an aliquot into an HPLC vial for
HPLC/ELSD/MS analysis. According to the LSD/MS analysis, the crude lipid ned
0.2% sterol esters (SE), 95.1% TAG, 0.4% sterols, and 0.5% 1,2-diacylglycerol (DAG). 5% of
the TAG fraction included a peak that eluted directly after the TAG peak, but did not give a
recognizable mass um.
Isolated TAG from this sample as determined by flash chromatography made up
approximately 92.4% of the crude oil. PL was not detected by weight or TLC after SPE
isolation. The major fatty acids (>50 mg/g) contained in the TAG were C1620 (189 mg/g),
C2025 n-3 (197 mg/g), and C22:6 n—3 (441 mg/g).
PTA-10208 Sample #2. The fatty acid profile of the biomass and extracted crude lipid
for PTA-10208 Sample #2 was determined using GC/FID. FAs in the biomass were
transesterifled in situ by ng 32.0 mg of biomass directly into a FAME tube, while a
sample ofthe extracted crude lipid was prepared by weighing 60.1 mg of crude lipid into a 50
mL volumetric flask and transferring 1 ml to a separate FAME tube. The estimated crude lipid
content ofthe s was ined to be 52.4% (as SUM of FAME) using GC with FlD
detection, while 48.0% (wt/wt) lipid was extracted from the dry biomass, giving a 91.7%
recovery oftotal lipid. The crude lipid was determined to be 95.3% fatty acids (as SUM of
FAME) using GC/FID. The major fatty acids contained in the crude lipid were C1620 (217.5
mg/g), C2025 n-3 (169.3 mg/g), and C2226 n-3 (444.1 mg/g).
The lipid class profile of the extracted crude lipid was determined by weighing 60.1 mg
of crude lipid into a 50 mL volumetric flask and transferring an aliquot into an HPLC vial for
HPLC/ELSD/MS analysis. According to the HPLC/ELSD/MS analysis, the crude lipid contained
0.2% SE, 95.7% TAG, 0.3% s, and 0.7% 1,2-DAG. 5.1% of the TAG fraction included a
peak that eluted directly after the TAG peak, but did not give a recognizable mass spectrum.
Isolated TAG from this sample made up approximately 93.9% of the crude oil. PL was
not detected by weight or TLC after SPE isolation. The major fatty acids (>50mg/g) contained
in the TAG were C1620 (218 mg/g), C2025 n-3 (167 mg/g) and C22:6 n-3 (430 mg/g).
PTA-10208 Sample #3. A sample of crude oil from the microorganism deposited under
ATCC ion No. PTA-10208 (Sample PTA-10208 #3) was analyzed using
HPLC/ELSD/MS. A total of 98.38% of lipids were recovered, with the sterol ester (SE) fraction
accounting for 0.32%, the TAG fraction accounting for 96.13%, the 1,3-diacylglycerol (DAG)
fraction accounting for 0.22%, the 1,2-DAG fraction accounting for 0.78%, and the sterol
on ting for 0.93%.
