Disclosed is a lead-free copper alloy for casting which contains 0.1-0.7% of S, 8% or less (excluding 0%) of Sn, and 6% or less (excluding 0%) of Zn, and in which a sulfide is dispersed and the average spheroidization ratio of the sulfide is 0.7 or greater. Due to this constitution, said lead-free copper alloy for casting has excellent mechanical properties such as strength, high pressure resistance and good machinability and, therefore, is useful as a starting material for faucet metal fittings, water faucet and so on, even though the alloy contains no lead which causes deterioration of water.

The present invention is directed to a method for producing an optical fiber having formyl groups on a core surface. In one embodiment, a plastic optical fiber having formyl groups on a core surface is obtained by immersing the core surface of the plastic optical fiber in a treating solution containing at least a 0.5 to 40 mM alkali metal hydroxide and a compound having formyl groups in water or lower alcohol solvent. In the other embodiment, a plastic optical fiber having formyl groups on a core surface is obtained by introducing a vic-diol group, a primary hydroxyl group or an alkenyl group on the core surface, and then oxidizing it. Turbidity on the core surface of the optical fiber thus obtained is minimized, thereby reducing the transmittance losses of light.

A biocatalyst is immobilized with a graft product of a polymer and saponified polyvinyl acetate containing a stilbazolium group as a photo-crosslinking group. The polymer is preferably gelatin, collagen, starch, cellulose, gum arabic, tragacanth gum, carrageenan, mannan, dextrin or alginic acid. The graft product is prepared by bonding the polymer to the polyvinyl acetate, either directly through functional groups of the polymer and polyvinyl acetate or through a crosslinking agent. The polymer provides affinity for the biocatalyst and by grafting the polymer to the saponified polyvinyl acetate, damage to cells upon immobilization is reduced. A liquid composition containing a biocatalyst and the graft product is added to an aqueous solution of an inorganic salt or an organic salt to form a granular gel and the gel is irradiated with actinic rays to cure the gel.

A continuous microorganism cultivating apparatus has a stock solution tank which receives a stock solution for a microbial reaction and is provided with a cylindrical filter through which the stock solution is passed. The stock solution is separated by the filter into filtrate containing a metabolic product and concentrated liquid containing microbes. The concentrated liquid is then recycled to the stock solution. The filter is a ceramic filter having a multitude of pores, which is connected to a back wash device.
