METHOD OF EFFICIENTLY MODIFYING SURFACE OF BACTERIUM

摘要

A bacterium having a functional substance on the surface; and a process for producing the bacterium. In particular, a bacterium such as, e.g., one which enhances intestinal absorption, is produced. Also provided is a compound represented by the general formula (I): wherein R1, R2, and R3 each independently is hydrogen or a protective group; R4 is hydrogen, optionally substituted acetyl, optionally substituted monophosphate, optionally substituted diphosphate, or optionally substituted triphosphate; W is -(C=O)-CH2-, -C=C-, or a group imparting a function; X is a single bond or -(CH2)n-; n is an integer of 1 to 10; and Y is -(C=O)-R8 (wherein R8 is alkyl), -C=CH, or a group imparting a function.
