摘要:
A method of identifying nucleotide sequences coding for signal peptides in lactic acid bacteria, using a DNA molecule comprising a transposon including a promoterless reporter gene from which DNA molecule a region between the LR and the reporter gene is deleted and the DNA molecule comprises a DNA sequence coding for a secretion reporter molecule. By deleting the region between the LR and the reporter gene, stop codons in-frame with the secretion reporter molecule is removed which upon transposition permits translational fusions from upstream the LR.

The present invention relates to a perfumed detergent tablet, the tablet comprising a clay mineral compound, and the perfume comprising less than 0.6% of Schiff-base by weight of the perfume composition.
摘要:
A perfumed detergent tablet comprises a clay mineral compound and a heavy metal ion sequestrant. The clay mineral helps disperse the tablet in aqueous media and acts as a fabric softener for laundered fabrics. The perfume is free of Schiff bases, such as those formed from anthranilates and aldehydes, which can discolor the clay.
