摘要:
A process for preparing L-tryptophan by fermentation which comprises cultivating on a medium containing ethanol as the main carbon source a microorganism of the genus Serratia that utilizes ethanol and has the ability to produce L-tryptophan, and recovering the accumulated L-tryptophan from the culture.
摘要:
A process for producing L-valine or L-lysine which comprises aerobically culturing a bacterium belonging to the genus Acinetobacter, which utilizes ethanol and has an ability to produce and accumulate L-valine or L-lysine, in a culture medium in which ethanol is the main carbon source to produce and accumulate L-valine and/or L-lysine and collecting.
摘要:
L-threonine is produced by aerobically culturing a bacterium belonging to the genus Acinetobacter, which utilizes ethanol and has an ability to produce and accumulate L-threonine, in a culture medium in which ethanol is the main carbon source to produce and accumulate L-threonine in a culture liquor and recovering L-threonine from the culture liquor. The bacterium is preferably a mutant of Acinetobacter calcoaceticus YK-1011 (Ferm-P No. 5910).
摘要:
A process for producing L-aspartic acid economically and efficiently from fumaric acid or a salt thereof and ammonia or an ammonium salt using a cultured product obtained by aerobically culturing an microorganism belonging to the Genus Brevibacterium and having resistance to .alpha.-amino-n-butyric acid.
摘要:
The present invention relates to a process for producing lipids, which comprises culturing bacteria capable of assimilating aliphatic hydrocarbons and accumulating lipids in medium containing aliphatic hydrocarbons until lipids are accumulated in the bacteria and then recovering the lipids therefrom, as well as to process for producing cosmetics which comprises using the lipids produced by said method.
摘要:
There are disclosed cosmetics which comprise N-acylamino acids containing acyl groups having specifically numbered carbon atoms, or derivatives thereof and which are well suited for hair growth, skin care and the like; N-acylamino acid compositions which are favorably usable for detergents, dispersants, emulsifying agents, antimicrobial drugs, antiseptics, ultraviolet absorbers and the like. The invention provides cosmetics which comprise N-acylamino acids containing acyl groups having odd-numbered carbon atoms, salts thereof or esters thereof; N-acylamino acid compositions; and further N-acylamino acids containing acyl groups having carbon atoms in an odd number in the range of 13 to 17 along with salts and esters thereof.
摘要:
The present invention relates to a sulfamoyl triazole derivative and a fungicide containing same as an effective component, the sulfamoyl triazole derivative being expressed by general formula (I): ##STR1## in which R.sup.1 and R.sup.2 are the same or different lower alkyl groups or an alkylene chain formed by integrating R.sup.1 and R.sup.2 and having 3 to 6 carbon atoms which may be substituted by a lower alkyl group; p is an integer 0 or 1; and A is a substituted aryl group.The fungicide does not damage field and garden plants and it is effective for preventing and curing various disease injury at very small dosages.
