Abstract: A method for the production of oligodextrans containing an .alpha.(1.fwdarw.2) bond which uses glycosyltransferase from Leuconostoc mesenteroides, particularly strain B-1299, sucrose and an accepter moiety such as glucose, maltose, isomaltose, isomaltotriose or methyl .alpha.-glucose. Optionally, this product may be further treated with an endodextranase or glucosamylase.

Abstract: The invention relates to the preparation of water-soluble L-tyrosine derivatives having the formula ##STR1## where R.sub.1 is a L-malyl, L-lactyl, L-glutamyl or L-aspartyl group, R.sub.2 is a --OH, --OM, methoxy, ethoxy or amino group and M is an alkaline metal, by enzymatic condensation of an acid selected among L-malic, L-lactic, L-glutamic and L-aspartic acids, with a L-tyrosine derivatives selected among the ethyl and methyl esters and the amide of L-tyrosine. The enzyme is obtained from a culture of Micrococcus casealyticus. The compounds where R.sub.1 is a L-malyl or L-lactyl group are new. Said L-tyrosine derivatives are useful in cosmetic and pharmaceutical compositions, such as tanning and sun compositions.
