The invention provides a method for producing sulfated polysaccharides by reacting a PAPS production/regeneration system utilizing the metabolic activity of a microorganism or a treated matter thereof with a microorganism expressing a sulfation enzyme or a treated matter or extract thereof upon mixing of inexpensive raw materials such as magnesium sulfate. The invention also provides a method for producing PAPS from inexpensive raw materials. The methods involve preparing a transformant (a) of a bacterium of the genus, which contains a gene encoding an ATP sulfurylase and a gene encoding an APS kinase, which are expressible, and in which a cell plasma membrane of the transformant (a) is substance-permeable, or a treated matter of the transformant (a), and conducting a reaction for producing PAPS by using a reaction solution containing ATP or an ATP source, a sulfate ion source, and the transformant (a) or the treated matter thereof.

Method for producing sulfated polysaccharide and method for producing PAPS

A method for manufacturing a float glass includes a step of melting a glass raw material, a step of forming the glass melted in the melting step into a glass ribbon while floating the glass on a molten metal, and a step of annealing the glass ribbon. In the forming step, a gas or a liquid containing a molecule having a fluorine atom present therein is blown to the glass ribbon having a viscosity of from 1.0&#xd7;10to 2.5&#xd7;10Pa&#xb7;s.

Method for producing glass sheet

A glass sheet has one surface and the other surface facing the one surface in a thickness direction, wherein a fluorine concentration (average fluorine concentration by SIMS at a depth of 1 to 24 &#x3bc;m) in the one surface is higher than that in the other surface. The following expression is satisfied: 0.07&#x2266;&#x394;F/&#x394;HO. &#x394;F (mol %) is a value obtained by subtracting an average fluorine concentration in the surface having the lower fluorine concentration from that in the surface having the higher fluorine concentration, and &#x394;HO (mol %) is an absolute value of a value obtained by subtracting an average HO concentration in the surface having the higher fluorine concentration from that in the surface having the lower fluorine concentration.
