Carbon dioxide fixation into amino acids of penicillium chrysogenum.
The relation of CO2 to the metabolism of Penicillium chrysogenum has been studied in three ways in this work: (1) attempts were made to replace C02; (2) radioactive C1402 was used to determine the conditions under which CO2 fixation occurred; and (3) attempts were made to identify some of the products of CO2 fixation, especially amino acids. These methods, singly or in combination, have been us...
متن کاملThe biochemistry and pharmacology of excitatory sulphur-containing amino acids.
1,-Glutamate is now well established as the predominant transmitter at fast-acting excitatory synapses in the mammalian central nervous system. Other amino acids such as L-aspartate and several acidic sulphur-containing amino acids (SAAs) which exhibit potent depolarizing actions similar to that of Lglutamate [I-31 are known to exist in the brain and/or are present in the brain under pathologic...
متن کاملThe oxidation of fatty acids by mycelium of Penicillium roqueforti.
SUMMARY Low concentrations of fatty acids with less than 14 carbon atoms were oxidized without a lag phase over a wide range of pH values by mycelium of Penicillium roqueforti. The effect of the fatty acids upon oxygen uptake by a given weight of mycelium, and the nature of the products of oxidation, were dependent upon the concentration and chain length of the fatty acid and the pH value of th...
متن کاملThe effect of nutrients on formation of penicillin by washed mycelium of Penicillium chrysogenum.
Many different substances are known to affect the yields of penicillin from growing cultures of Penicillium chrysogenum. Under the usual conditions, it is difficult to distinguish between the effect of a substance on growth of the mould (and hence the indirect effect on production of penicillin) and its direct effect on antibiotic synthesis. The use of washed mycelium (Halliday & Arnstein, 1956...
متن کاملProduction of penicillin with waste mycelium Penicillium chrysogenum as the sole source of nitrogen.
In a preliminary communication (Ghosh, 1959) it was reported that fresh and wet mycelium of Penicillium chrysogenum, as obtained from a rotary filter in a penicillin plant, could be well utilized as the sole source of nitrogen for penicillin production by the mold either in shaken flask or in aerated and agitated large fermentors. The waste mycelium did not need any pretreatment whatsoever and ...
