The part played by each microorganism in the food chain and its influence on the behaviour of the other two in this association were elucidated. The major products of cellulose fermentation were formic, acetic and lactic acids, ethanol, hydrogen and carbon dioxide. The hydrolysis of cellulose was slow; 1.37 mg equivalent of glucose per ml medium per hour was released. Desulfovibrio oxidized the organic acids, alcohol and hydrogen by dissimilatory sulfate reduction and sulfide and acetate were accumulated in the medium. The rate of sulfate reduction depends on the rate of cellulose fermentation.In the presence of phototrophic bacteria, the end products of cellulose degradation and sulfate reduction disappeared from the medium and the protein content increased highly. The growth yield constant increased five times when the cellulolytic organism was associated with the two sulfur bacteria. The absence of Desulfovibrio perturbed the functioning of the trophic chain, as the rate of sulfate reduction partly determines the growth of Chromatium. Chromatium seems to hinder the anaerobic degradation of cellulose, whereas Desulfovibrio seems to enhance it. The microorganisms behave differently in pure and mixed cultures.</div>","PeriodicalId":101290,"journal":{"name":"Zentralblatt für Bakteriologie Mikrobiologie und Hygiene: I. Abt.

During temperature rise in spring the VLO values rise to a characteristic level persisting from June to September. A decline occurs at this time, except in sites polluted from sugar plants, where there is a delay of appr. one month.In the relatively stable period the prevalence of VLO in the recipients is appr. 10–100 per ml water and 1.000–10.000 per gram sediment while the corresponding values for the control are 1–10 per ml and 100–1000 per gram, respectively.Thus fish living in these recipients are exposed to a ten times higher risk from VLO, which is reflected in a higher prevalence of an ulcus disease in cod. The complicated nature of pollution induced diseases makes it impossible directly to correlate VLO and disease prevalence. Prevalence studies of VLO in marine recipients give valuable information on growth conditions (“organic pollution”) for marine vibrios and the risk to fish, wild living and cultured. Therefore this group of bacteria should to be added to the list of marine indicator organisms, where the indication is based on the environmental risk.</div>","PeriodicalId":101290,"journal":{"name":"Zentralblatt für Bakteriologie Mikrobiologie und Hygiene: I.

After 10 days of shrimp ice storage, Plano-coccus and Pseudomonas were the predominant microorganisms present in Penaeus shrimp. All isolates recovered exhibited good growth over a range of pH 7–10, 5–35 °C and 5–120 g NaCl/1. Proteolysis studies revealed that P. citreus isolates were able to hydrolyze gelatin, cottonseed, soy and more important to the fisheries microbiologists, shrimp protein. P. citreus grew well at ice and refrigerated temperatures (5 °C) and all isolates tested produced an active extracellular enzyme system capable of degrading shrimp protein at this temperature. P. citreus counts increased in the inoculated shrimp stored at 5 °C from 3.0 x 103 bacteria/gram to 1.5 × 108 bacteria /gram at the 16th day. The potential of P. citreus as a “spoiler” of raw shrimp was shown by the rapid increase in total volatile nitrogen/amino acid nitrogen (TVN/AA-N) ratio, pH and trimethyl-amine nitrogen (TMN) content as well as the reduction in percent total extractable protein (TEP) of the inoculated samples. The extracellular proteolytic enzyme of P. citreus was active at refrigeration or iced temperatures; however, maximum activity was exhibited at 35 °C and pH 8. The importance of the extracellular protease enzyme for shrimp quality is discussed.</div>","PeriodicalId":101290,"journal":{"name":"Zentralblatt für Bakteriologie Mikrobiologie und Hygiene: I. Abt.

Both properties were proved to be plasmid determined (J. Jofre et al., J. Bact. 138, 721–725). Citrate utilization was transferred by conjugation from K. pneumoniae C3 to Escherichia coli K12. Moreover, the transfer of the ability to biosynthesize proline from strain C3 to well-characterized Pro- strains of E. coli established that loci proA and proB, but not proC, are complemented by the plasmid herein described. E. coli exconjugants transferred simultaneously the abilities to utilize citrate and to biosynthesize proline by conjugation to other E. coli strains. Plasmid DNA was detected in E. coli exconjugants either by cesium chloride-ethidium bromide ultracentrifugation or by agarose gel electrophoresis. Gel profiles established that a single plasmid of an estimated molecular weight of 57 megadaltons is present in all examined E. coli exconjugants. Pro−E. coli were transformed to Pro+ Cit+ with plasmid DNA of exconjugants. Also, a Cit-, Pro− and non-glutamic acid excreting strain derived from C3 was rendered Cit+, Pro+ and glutamic acid excretor by transformation with plasmid DNA from E. coli exconjugants.
