Neurons Controlling Aplysia Feeding Inhibit Themselves by Continuous NO Production
BACKGROUND Neural activity can be affected by nitric oxide (NO) produced by spiking neurons. Can neural activity also be affected by NO produced in neurons in the absence of spiking? METHODOLOGY/PRINCIPAL FINDINGS Applying an NO scavenger to quiescent Aplysia buccal ganglia initiated fictive feeding, indicating that NO production at rest inhibits feeding. The inhibition is in part via effects...
متن کاملPenicillin Production by High-Yielding
The development and study of strains of Penicillium chrysogenum that give high yields of penicillin has been a major project at the University of Wisconsin during the past 12 years. Many thousands of cultures have been screened for their penicillin-producing ability in the Botany Department of the University. The methods used for the production and screening of mutants, the genealogy of the out...
متن کاملPenicillin production in corn steep media with continuous carbohydrate addition.
The work reported here presents the results of an investigation into the replacement of lactose by glucose or by sucrose in a corn steep liquor medium for the production of penicillin. Previous work has established (Johnson, 1946) that glucose and sucrose are metabolized by Penicillium chrysogenum at a more rapid rate than is lactose. Also, it has been shown that a maximum rate of penicillin pr...
متن کاملPenicillin Production in Continuous Stirred Tank Reactor by Penicillium chrysogenum Immobilized in Agar
A previously developed immobilization technique involving agar as matrix is investigated further in penicillin production by P. chrysogenum ATCC 10238 at reactor level. Several modifications were found to decrease the germination lag time, including a higher spore concentration, an increased porosity of gel, and decreasing the mass transfer barrier. This approach enabled the production of penic...
متن کاملProduction of Penicillin Acylase.
The production of penicillin acylase by Escherichia coli Ny.I/3-67 has been increased by phenylacetic acid and phenoxyacetic acid, which themselves strongly inhibit the function of this specific enzyme. Other carbonic acids also increased penicillin acylase production, but to a lesser degree; they also weakly inhibited enzyme function. The production of this enzyme was effectively repressed wit...
