A method of producing a lipolytic enzyme comprising the steps of: (i) providing a transformed or transfected Trichoderma reesei cell comprising a) at least one heterologous nucleotide sequence encoding a lipolytic enzyme comprising an amino acid sequence shown as SEQ ID NO: 1 or SEQ ID NO: 2 or an amino acid sequence which has at least 40% sequence identity to SEQ ID NO: 1 or 2; and/or b) at least one heterologous nucleotide sequence encoding a lipolytic enzyme wherein the nucleotide sequence comprises the nucleotide sequence shown as SEQ ID NO: 3 or SEQ ID NO: 4 or a nucleotide sequence which has at least 40% sequence identity to SEQ ID NO: 3 or SEQ ID NO: 4; and/or c) at least one heterologous nucleotide sequence encoding a lipolytic enzyme wherein the nucleotide sequence comprises the nucleotide sequence which hybridizes to SEQ ID NO: 3 or SEQ ID NO: 4 or a nucleotide sequence which is at least 40% sequence identity to SEQ ID NO: 3 or SEQ ID NO: 4 or the complement of any thereof under stringent conditions; and (ii) culturing the cell under conditions to allow for expression of said heterologous nucleotide sequence(s) encoding said lipolytic enzyme; and (iii) raising the pH at the end of the fermentation to a pH above the pH of the culture conditions in step (ii). (i) providing a transformed or transfected Trichoderma reesei cell comprising a) at least one heterologous nucleotide sequence encoding a lipolytic enzyme comprising an amino acid sequence shown as SEQ ID NO: 1 or SEQ ID NO: 2 or an amino acid sequence which has at least 40% sequence identity to SEQ ID NO: 1 or 2; and/or b) at least one heterologous nucleotide sequence encoding a lipolytic enzyme wherein the nucleotide sequence comprises the nucleotide sequence shown as SEQ ID NO: 3 or SEQ ID NO: 4 or a nucleotide sequence which has at least 40% sequence identity to SEQ ID NO: 3 or SEQ ID NO: 4; and/or c) at least one heterologous nucleotide sequence encoding a lipolytic enzyme wherein the nucleotide sequence comprises the nucleotide sequence which hybridizes to SEQ ID NO: 3 or SEQ ID NO: 4 or a nucleotide sequence which is at least 40% sequence identity to SEQ ID NO: 3 or SEQ ID NO: 4 or the complement of any thereof under stringent conditions; and a) at least one heterologous nucleotide sequence encoding a lipolytic enzyme comprising an amino acid sequence shown as SEQ ID NO: 1 or SEQ ID NO: 2 or an amino acid sequence which has at least 40% sequence identity to SEQ ID NO: 1 or 2; and/or b) at least one heterologous nucleotide sequence encoding a lipolytic enzyme wherein the nucleotide sequence comprises the nucleotide sequence shown as SEQ ID NO: 3 or SEQ ID NO: 4 or a nucleotide sequence which has at least 40% sequence identity to SEQ ID NO: 3 or SEQ ID NO: 4; and/or c) at least one heterologous nucleotide sequence encoding a lipolytic enzyme wherein the nucleotide sequence comprises the nucleotide sequence which hybridizes to SEQ ID NO: 3 or SEQ ID NO: 4 or a nucleotide sequence which is at least 40% sequence identity to SEQ ID NO: 3 or SEQ ID NO: 4 or the complement of any thereof under stringent conditions; and (ii) culturing the cell under conditions to allow for expression of said heterologous nucleotide sequence(s) encoding said lipolytic enzyme; and (iii) raising the pH at the end of the fermentation to a pH above the pH of the culture conditions in step (ii).
