In order to excavate thermo-alkaline lipases from bacterial living in extreme conditions
we try to express new gene from
Thermosyntropha lipolytica
DSM 11003
an anaerobic
thermophilic
alkali-tolerant bacterium which grows in alkaline hot springs Lake Bogoria in Kenya and explore its application in biodiesel production. The lipase gene (
tll
1) of 1434 bp were ligated at the
Nco
I /
EcoR
I sites of the expression vectors pET28a to yield the construct of pET28a-TLL1. The strain harboring pET28a-TLL1 was cultivated for expression at 25℃
the specific activity of 1.99 U/mg protein were detected in disrupted cells. The recombinant lipase
Tl
LipA was purified by a simple two-step procedure involving heat treatment and Ni-chelating affinity chromatography. The subunit of purified
Tl
LipA showed a molecular mass of 53×10
3
on 12% sodium dodecyl sulfate polyacrylamide gel electrophoresi
s (SDS-PAGE). The purified
Tl
LipA exhibited optimal activity at 65℃ and pH 8.0 and it was stable from 55℃ to 65℃. The enzyme remained above 80% of its original activity at pH ranging from 7.0 to 11.0 and at room temperature for 1 h. The activity of
Tl
LipA was little unaffected by Co

and a little activated by Mg

and Mn

but were significantly inhibited by Zn

and SDS
and Tween 80 under the assay conditions. The purified recombinant
Tl
LipA had a specific activity of 22.11 U/mg protein using
p
-nitrophenyl palmitate (
p-

p
-nitrophenyl laurate (
p-
NPL)
p
-nitrophenyl myristate (
p

p
-nitrophenyl caproate (
p-

moreover
Tl
LipA exhibited a strong preference for
p
-nitrophenol decanoate (
p
-NPD) and
p
-nitrophenyl octoate (
p
-NPO). Using recombinant lipase as a catalyst to prepare biodiesel in a solvent-free system
with a water content of 20%
an enzyme dosage of 200 U/g oil
and an alcohol-to-oil ratio of 4∶1
catalyzed soybean oil reaction at 55℃ for 48 h
