Abstract
This paper describes a mathematical model of fluorescent biological particles composed of bacteria, viruses, or proteins. The fluorescent and/or light absorbing molecules included in the model are amino acids (tryptophan, etc.); nucleic acids (DNA, RNA, etc.); coenzymes (nicotinamide adenine dinucleotides, flavins, and vitamins B₆ and K and variants of these); and dipicolinates. The concentrations, absorptivities, and fluorescence quantum yields are estimated from the literature, often with large uncertainties. The bioparticles in the model are spherical and homogeneous. Calculated fluorescence cross sections for particles excited at 266, 280, and 355 nm are compared with measured values from the literature for several bacteria, bacterial spores and albumins. The calculated 266- and 280-nm excited fluorescence is within a factor of 3.2 of the measurements for the vegetative cells and proteins, but overestimates the fluorescence of spores by a factor of 10 or more. This is the first reported modeling of the fluorescence of bioaerosols in which the primary fluorophores and absorbing molecules are included.

Abstract
Benziman, Moshe (The Hebrew University of Jerusalem, Jerusalem, Israel), and Y. Galanter. Flavine adenine dinucleotide-linked malic dehydrogenase from Acetobacter xylinum. J. Bacteriol. 88:1010-1018. 1964.-The properties of the pyridine nucleotide-nonlinked malic dehydrogenase of Acetobacter xylinum were investigated in the supernatant fluid obtained by high-speed centrifugation of sonic extracts. Ferricyanide, phenazine methosulfate, and to a lesser extent dichlorophenolindophenol were active as oxidants for malate oxidation. After acid ammonium sulfate precipitation, the enzyme lost its malate-oxidizing activity. The enzyme was reactivated by low concentrations of flavine adenine dinucleotide (FAD) but not by flavine mononucleotide (FMN) or riboflavine. Atabrine inhibited the enzyme, and the inhibition was relieved by FAD but not by FMN or riboflavine. Malate-oxidizing activity was inhibited by hematin. The inhibition was prevented by imidazole or globin. o-Phenanthroline, 8-hydroxy quinoline, alpha,alpha'-dipyridyl, and p-chloromercuribenzoate inhibited malate oxidation. Amytal markedly inhibited oxidation of malate in the presence of oxygen, phenazine methosulfate, or dichlorophenolindophenol, but not in the presence of ferricyanide. The results suggest that the malic dehydrogenase of A. xylinum is a FAD enzyme, which contains an ironbinding site essential for its activity. Nonheme iron and sulfhydro groups are possibly involved in enzyme activity. The malic dehydrogenase is functionally linked to the cytochrome chain.

Abstract
Ejaculates were collected by artificial vagina from 11 Angora goats, once or twice weekly, between April and July in two successive years. The mean +/- SEM ejaculate volumes each year were 0.8 +/- 0.30 and 0.98 +/- 0.52 ml; the sperm concentrations were 3.33 +/- 0.49 and 2.94 +/- 0.45 x 10(9)/ml, and the pH values were 7.01 +/- 0.34 and 7.20 +/- 0.17. The concentrations (mg/100ml) of fructose (875 +/- 97) and lactic acid (73 +/- 17) in goat seminal plasma were sufficiently high to be important substrates for maintenance of sperm motility. Only trace amounts of glucose were present in seminal plasma. The glycerylphosphorylcholine (GPC) concentration of seminal plasma (809 +/- 154 mg 100 ml ) was correlated with whole semen sperm concentration (P < 0.001), indicating that GPC is of epididymal origin. Goat sperm are not likely to utilize GPC as a substrate and its metabolizable derivatives, glycerophosphate (3.3 +/- 1.1 mg 100 ml ) and glycerol (1.8 +/- 1.0 mg 100 ml ), were not present in sufficiently high concentrations to be significant as energy sources for the sperm. The mean concentration of citric acid was 331 mg 100 ml seminal plasma. Colored semen was consistently produced by eight bucks, and in yellow, light yellow and white ejaculates, the seminal plasma riboflavin (mug/ml) concentrations were 5.38 +/- 2.89, 3.09 +/- 0.85 and 1.73 +/- 0.88, respectively. This suggests that the color is due to riboflavin, which is probably produced by the vesicular glands since the concentration of riboflavin in the seminal plasma was correlated with fructose and citric acid levels.
