A domestic method of treating a textile, the method comprising the step of: treating a textile with an aqueous solution of 0.5 to 20 g L of the laundry detergent composition. LAUNDRY DETERGENT COMPOSITION FIELD OF INVENTION The present invention concerns the use of alkoxylated polyarylphenols with a lipid esterase in a detergent formulation. BACKGROUND OF THE INVENTION Lipid esterase are enzymes that hydrolyse the ester bonds in a lipid. They can be produced by a large number of living cells for example bacteria, yeasts and fungi. In the laundry context cleaning lipid esterase are well-known which enhance the cleaning of fabrics. Examples of cleaning lipid esterases include first wash lipases. Lipid esterases are discussed in Enzymes in Detergency edited by Jan H. Van Ee„ Onno Misset and Erik J. Baas (1997 Marcel Dekker, New York). GB 2 007 692 discloses anti-soiling and anti-redeposition adjuvants for detergent compositions include at least one polymer A , said polymer itself having anti-soiling and anti- redeposition properties, at least one solubilizing and dispersing agent B for said polymer A , and at least one water repellent C for said agent B. EP 2 767 581 discloses a method of laundering a fabric comprising the steps of; (i) contacting the fabric with a lipid esterase selected from class E.C. 3.1 . 1 .3, class E.C. 3.1 . 1 . 1 or a combination thereof; (ii) contacting the fabric from step (i) with a soil; (iii) contacting the fabric from step (ii) with a laundry detergent composition, wherein the laundry detergent composition optionally comprises a detersive surfactant, and optionally comprises a lipid esterase. There is a need to improve the performance of cleaning lipid esterase enzymes in detergent formulations. SUMMARY OF THE INVENTION We have found that the combination of a lipid esterase and alkoxylated polyarylphenols gives enhanced cleaning. In one aspect the present invention provides a laundry detergent composition comprising: (i) from 0.5 to 20 wt%, preferably from 2 to 14 wt%, most preferably from 3 to 9 wt%, of an alkoxylated polyarylphenols having an average of 5 to 70 alkoxy groups (ii) from 4 to 50 wt% of an anionic surfactant, other than the alkoxylated polyarylphenol, preferably the level of anionic surfactant is from 6 to 30 wt%, more preferably from 8 to 20 wt%; and, (iii) a lipid esterase at a level of from 0.0005 to 0.5 wt % of pure enzyme, preferably from 0.05 to 0.3 wt % , wherein the lipid esterase is selected from Triacylglycerol lipase (E.C. 3.1 . 1 .3); Carboxylic ester hydrolase (E.C. 3.1 . 1 .1); Cutinase (E.C. 3.1 . 1 .74); Sterol esterase (E.C. 3.1 . 1 .13); and, Wax-ester hydrolase (E.C. 3.1 . 1 .50). The level of enzyme as referred to as "pure" is simply the level as measured calculated as in the pure form of enzyme rather than in admixture with adjuncts as the enzyme is commercially provided. In another aspect the present invention provides a domestic method of treating a textile, the method comprising the step of: treating a textile with an aqueous solution of 0.5 to 20 g/L of the laundry detergent composition as defined herein. The domestic method is preferably conducted at a temperature from 283 to 3 13K under atmospheric pressure in domestic tap water. DETAILED DESCRIPTION OF THE INVENTION Alkoxylated polyarylphenol dispersant The alkoxylated polyarylphenol dispersant is a phenol to which aryl groups are covalently attached and the molecule is alkoxylated preferably with ethoxy groups. The alkoxylated polyarylphenol may be charged or uncharged, preferably negatively charged or uncharged, most preferably uncharged (neutral). Preferably the alkoxylated polyarylphenol is an alkoxylated tristyrylphenol. The alkoxylated polyarylphenol contains an average of 5 to 70 alkoxy groups, preferably 10 to 30 alkoxy groups. Preferably the alkoxylation is ethoxylation. Preferably the alkoxylated polyarylphenol has 2 or 3 aryl groups attached to the phenol. Preferably they are in the 2,4 or 2,4,6 position on the phenol. The alkoxylate is attached to the 1 position. The alkoxylate may be capped by charged groups such as phosphate or sulphate. Preferably the alkoxylate is capped by a hydrogen atom. The aryl group in the alkoxylated polyarylphenol is preferably selected from, phenyl, tolyl, naphthyl, tetrahydronaphthyl, indanyl, indenyl, styryl, pyridyl, quinolinyl, and mixtures thereof, most preferably styryl. Most preferably, the alkoxylated polyarylphenol is polyethylene glycol mono(2,4,6-tris(1- phenylethyl)phenyl) ether (CAS-No: 70559-25-0) with the following structure: Where n is selected from 5 to 70, preferably n is selected from: 10; 11; 12; 13; 14; 15; 16; 17; 18; 19; 20; 2 1; 22; 23; 24; 25; 26; 27; 28; 29; 30; 3 1; 32; 33; 34; 35; 36; 37; 38; 39; 40; 4 1; 42; 43; 44; 45; 46; 47; 48; 49; 50; 5 1; 52; 53; and, 54, most preferably n is selected from: 10; 11; 12; 13; 14; 15; 16; 17; 18; 19; 20; 2 1; 22; 23; 24; 25; 26; 27; 28; 29; 30.

ABSTRACT CHARACTERIZATION OF YDR036C FROM Saccharomyces cerevisiae by Matthew F. Rouhier Beta-hydroxyisobutyryl-CoA (HIBYL-CoA) hydrolases are found ubiquitously in eukaryotes where they function in the catabolism of valine. A homologous enzyme (YDR036C) is also present in yeast where valine catabolism is distinctly different and does not require a HIBYL-CoA hydrolase. Like the other eukaryotic hydrolases, the yeast hydrolase is a member of the crotonase super-family which catalyzes various reactions using CoA thioester substrates. Crotonases typically function in fatty acid degradation which is peroxisomal in yeast while YDR036C is found strictly in mitochondria. Like other HIBYL-CoA hydrolases the yeast enzyme demonstrated activity toward beta-hydroxyacyl-CoAs, but unlike the other HIBYL-CoA hydrolases the yeast activity is greatest with beta-hydroxypropionyl-CoA (3-HP-CoA). Further characterization of the active site has determined that the preference of the hydrolases for 3-HP- CoA or HIBYL-CoA is dependent upon the residue at position 177. The glutamate at position 121 is responsible for the coordination with the beta-hydroxyl group and replacement with valine renders the enzyme non-specific for a hydroxyl group. Another unique feature to yeast hydrolases is the presence of a C-terminal tail of 80 amino acids, which when removed renders the enzyme inactive, suggesting that it may play a role in substrate binding.

E-mail: [email protected]. URL: http://www.icp.csic.es/abg 1 ABSTRACT The sterol esterase from the ascomycete Ophiostoma piceae was immobilized on novel polyacrylate-based epoxy-activated carriers (DilbeadsTM). Six supports with particle sizes between 120-165 m were prepared varying the composition of monomers, crosslinkers and porogens. Their surface areas and porosities were determined by N2 adsorption and mercury intrusion porosimetry. The pore volumes ranged from 0.63 to 1.32 cm3/g, but only DilbeadsTM RS and NK had narrow pore size distributions (with maxima at 33.5 and 67.0 nm, respectively). The distribution of the enzyme in the support was studied by fluorescence confocal microscopy. The immobilized esterase on DilbeadsTM TA showed a significant pH and thermal stability and was assayed in the continuous hydrolysis of cholesteryl esters -present in the pulp industry process waters-.

    Supplementary table S4 – Comparison of the ScHaa1- and CgHaa1- dependent regulatory networks. The dataset of C. glabrata genes herein found to be regulated by CgHaa1 under acetic acid stress was compared with the dataset of genes described to be regulated by ScHaa1, based on the information available at the YEASTRACT database. Identification of orthologues was performed using the Yeastmine algorithm available at the Candida Genome database website after which a manual curation of the data based on BLASTP was performed. The promoter region of S. cerevisiae or C. glabrata genes was searched for the described ScHaa1 binding site (5’-(G/C)(A/C)GG(G/C)-3’, designated Haa1-responsive element – HRE; Mira et al., 2011) using the DNA pattern matching algorithms embedded in the RSA tools website. Cells highlighted in grey correspond to the S. cerevisiae genes found to be regulated by ScHaa1 specifically under acetic acid stress, based on the dataset of Mira et al., (2010). Acetic acid-responsive genes regulated by ScHaa1 only C. glabrata S. cerevisiae S. cerevisiae ORF Function promoter harbors promoter harbors orthologue an HRE motif an HRE motif Ortholog(s) have actin binding, cytoskeletal regulatory protein binding, enzyme activator CAGL0A00891g YLR319C No No activity Ortholog(s) have role in double-strand break repair, meiotic sister chromatid segregation, CAGL0A00913g recombinational repair, replication fork processing and Cul8-RING ubiquitin ligase complex, YLR320W No No nucleus localization CAGL0A01001g No Description Available YLR326W Yes

    Table S2. Mass spectrometry based quantitation (LFQ scores) of proteins co-purifying from yeast with ExoY-TAP. PEP - posterior error probability - the probability of a false hit given the peptide identification score and length of peptides (defined in Cox, J. & Mann, M. MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide quantitation. Nat Biotechnol. 2008 Dec;26(12):1367-72. doi: 10.1038/nbt.1511.) LFQ - Label Free Quantitation score - proportional to the average peptide signal intensity for all the peptides used to identify a given protein. Approximates the relative amounts of protein and can be used to compare protein levels between two conditions.
