By the government policy, the number of school which is routing a school lunch system is increasing. Since school lunch play an important part of the basis of physical strength in high, middle and elementary schools. There are many arguments over the safety of the soy-sauce made from acid-hydrolyzate. We study public and private high, middle and elementary schools located in Uijeongbu-city and the northern Seoul area. As a result, it showed us that the using rate of commercial fermented soy sauce was $46.3\%$, which was the highest. Chemical soy sauce followed it on presenting $4l/8\%$ and acid-hydrolyzated soy sauce was$11.9\%$.

Pedobacter sp. PAMC 27299 with humic acid cultivated on low temperature was isolated from the moss debris on the coast of the Barton Peninsula of King George Island of the maritime Antarctic region. Here, we present the complete genome sequence of Pedobacter sp. PAMC 27299, which contains 6,147,290 bp with a G+C content of 40.54%. PAMC 27299 may possess cold-adapted humic acid degradation enzymes with implication on global warming.

Antielastic fragment in GBⅠ-Ⅱ differ on $P_1$ site with that of antitryptic fragment in LBI. To obtain further understanding of the role of amino acid residue near the reactive site, specificity of $P_1$ site and loop size, Tyr substituted cyclic nonapeptide and cyclic pentapeptide were synthesized and the inhibition constants for some proteinases were calculated by Dixon method. Cyclic nonapeptide showed no inhibition for chymotrypsin but appeared low inhibitory activity for trypsin and elastase and that of cyclic pentapeptide possessed inhibitory activity for chymotrypsin.

This study was conducted to investigate the effects of steam flaking of corn grains on in situ dry matter degradability in the rumen and contents of mycotoxins (aflatoxin, ochratoxin) during storage. Yellow dent corns imported from USA and India were flaked, and stored for 8 weeks under the standard temperature and pressure (STP; $25^{\circ}C$/ 1 atm.). Experimental treatments were composed of four corn grains (untreated-USA corn, USCW; steam flaked-USA corn, USCF; untreated-India corn, IDCW; steam flaked-India corn, IDCF) with 4 replications according to 9 storage periods (0, 1, 2, 3, 4, 5, 6, 7, 8 week). Two ruminally cannulated Holstein bulls were used for in situ trial. Pathogen contamination trial was performed by comparing the mycotoxin contents in corns during storage periods. Dry matter disappearance rate in the rumen was about 3.0 to 44.1% higher (P<0.05) for USCW than IDCW, but was not difference between USCF and IDCF. With steam flaking of corn, dry matter degradability in the rumen was significantly (P<0.05) increased in corn from India, but was not affected in corn from USA. Aflatoxin content was very low level in corns from USA and steam flaked corns, but was higher than the tolerance limit of domestic aflatoxin content regulation when IDCW was stored over 6 week under STP. Ochratoxin content was low level in all treatments. From above results, it is reasonable that the corn imported from India might be flaked for enhance the ruminal DM degradability and safe from aflatoxin pathogen.
