    Notes: The dependence of the Raman spectrum of PET fibers on take-up speed (TUS) during high-speed spinning is examined. It is found that conformational change, orientation, and crystallinity, all different functions of TUS as a processing variable, are reflected in the spectra. The data, as well as those from thermal annealing of PET fibers, are shown to be consistent with those from other techniques, leading to a set of equations from which a number of properties of the PET fibers can be determined from the Raman spectrum alone.

    Notes: The far infrared spectra of dimethyl sulfoxide and several aliphatic nitriles have been studied with a view towards elucidating the mechanism responsible for the intense absorption bands which have been observed in this region. Spectra of pure liquids, solid DMSO, DMSO-d6, CD3CN, and dilute solutions in non-polar solvents are presented. The results are discussed in terms of the possible mechanisms proposed for these absorptions.

    Notes: Analysis is made of the asymmetry of the carbonyl stretching vibration of poly(ethylene terephthalate) and poly(propylene terephthalate) as a function of annealing frrom amorphous to crystalline polymer. An apparently anomalous behavior of carbonyl band half-width as a function of density for PPT is shown to be due to this asymmetry. The results are interpreted in terms of the conformational redistribution which occurs upon annealing.

    Dialysis fermentation. II. Kinetic analysis of salicylic acid production via cell growth and maintenanceArticle No 4978, Michigan Agricultural Experiment Station. (1970)

    Notes: A kinetic analysis was made of the relationship between salicylate production from naphthalene and growth of Pseudomonas fluorescens in semicontinuous dialysis culture. The specific rates both of product formation and growth initially were increased by the diffusional withdrawal of salicylate, but subsequently were reduced to low levels despite continued salicylate removal. Productivity and growth were correlated by the Luedeking-Piret equation in an initial nondialysis period and in the early stages of dialysis fermentation, when specific growth rates exceeded. 005 hr-1. Below this level of growth at later stages of dialysis fermentation, the specific production rate was correlated only with total cell mass by a proportionality constant of .035 hr-1, which was attributed to maintenance metabolism. Maintenance accounted for about 84% of the total salicylate produced, while growth-associated metabolism accounted for the remainder.

    Notes: Dialysis was attempted as a means to alleviate the product-activated controls presumed to limit the formation of threonine by an auxotrophic mutant of Escherichia coli strain W. The occurrence of inhibition rather than enhancement of yields by dialysis was traced to the fact that threonine actually was not inhibiting its own synthesis. Instead, α,ε-diaminopimelic acid became depleted, but the imbalance could not be corrected by exogenous replacement.

    Effect of alkylbenzenes on n-alkane utilization (1969)

    Notes: It has been shown that alkylbenzenes which do not support growth of Pseudomonas aeruginosa exert a stimulatory or inhibitory effect on the utilization of n-alkanes by this organism. The effect is a function or the number of methyl substitutions to the benzene ring and the concentration of aromatic hydrocarbon. The alkylbenzenes have been shown to exert the stimulatory and inhibitory effect, on all phases of growth. The data suggests different mechanisms involved in the inhibition by benzene and p-xylene but a similar mechanism by all of the stimulatory compounds. Warburg data demonstrates changes in the rate of oxygen uptake in the presence of trimethylbenzene at different stages of the fermentation. The release of water soluble material in the presence of trimethylbenzene suggests a permeability effect on the cells.

    Notes: The conversion of naphthalene to salicylic acid by Pseudomonas fluorescens was studied as a model for dialysis fermentation. In a demonstration experiment, the continual removal of the product by dialysis and by intermittent replenishment of the dialysate reservoir caused cyclical changes in the concentrations of viable cells and product. The cumulative total amount of both cell mass and salicylate, however, continued to increase steadily until the experiment was terminated after 15 days. At this time the rate of product formation was highest and still increasing, although less than 10% of the cells were viable. The terminal amount of salicylate was about 20-fold greater than the maximum reached in the control fermentation, and was calculated to be 2.6-fold more productive even if the control were optimally recycled. Methods were projected to achieve still further improvements.

    The relationship of substrate, growth rate, and maintenance coefficient to single cell protein production (1973)

    Notes: Various organic compounds were assessed as potential substrates for single cell protein production. Substrate evaluation was based on the costs associated with the substrate, oxygen, and heat yield coefficients: Ysub, Yo, and Ykcal, respectively. Yo, and Ykcal, were calculated from experimental values of Ysub, and from the elemental composition of bacterial cells. The dependence of the yield coefficients on the specific growth rate (μ) and maintenance coefficient (m) also was assessed. The analysis disclosed that m caused two- to threefold variations in the yield coefficients as μ was increased from 10% to 100% of μmax. The effect of different m values at constant specific growth rates also was determined. The value of m had a significant effect on the yield coefficients even at high specific growth rates. Assignment of cost factors to the yield coefficients provided an estimation of the impact m and μ on biomass production costs.
