Today, this disease is the most commonly reported infectious disease in the U.S. The natural environment of the etiological agent, Neisseria gonorrhoeae, is man. In this host, the organism usually parasitizes mucosal surfaces populated by columnar epithelial cells. Under certain conditions, the gonococcus may disseminate or spread to adjacent organs. The gonococcus is well adapted to its environment and is a successful parasite. Until recently, gonococci were uniformly sensitive to penicilin. However, a plasmid encoding beta-lactamase has been identified in some isolates. Most strains exhibit specific requirements for various amino acids, vitamins, purines, and pyrimidines. Only glucose, pyruvate, and lactate are utilized as sources of energy. Glucose is dissimilated by a combination of the Entner-Doudoroff and pentose phosphate pathways. A tricarboxylic acid cycle is also present and active under certain conditions. Structurally, the cell envelope of the gonococcus resembles that of a typical Gram-negative bacterium. Gonococci are highly autolytic, especially in older cultures or after depletion of the energy source. Autolysis is not due solely to peptidoglycan hydrolysis, but appears to involve a destabilization of the outer membrane as well. Cell surface components such as pili, lipopolysaccharide, outer membrane proteins, and a capsule are associated with the virulence and pathogenicity of this organism.</p>","PeriodicalId":75751,"journal":{"name":"CRC critical reviews in microbiology","volume":"7 2","pages":"93-189"},"PeriodicalIF":0.0,"publicationDate":"1978-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/10408417909083071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11333330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bacteria attaching to new wood were predominantly stalked bacteria whereas the microbial flora of old wood reflected that of the surrounding water and sediment.

Various methods have been proposed for increasing rates of petroleum biodegradation, including physical or chemical modification of petroleum polutants, modification of environmental parameters around polluting oil, and modification of microbial populations around petroleum pollutants. Physical or chemical means for stimulating petroleum biodegradation include removal of particular petroleum fractions by dissolution, burning, and emulsification. Modification of environmental parameters (such as concentrations of essential nutrients, especially nitrogen, phosphorus, and oxygen) has shown the greatest promise for stimulating petroleum biodegradation. Forced aeration and addition of commercial fertilizer combinations in contained systems, addition of fertilizer with tilling in soil, and addition of fertilizer that has been rendered oleophilic in open systems have all been shown to effectively stimulate petroleum biodegradation. Modification of microbial populations by seeding with oil-degrading microorganisms appears to be valuable in stimulating petroleum biodegradation only in limited situations where the naturally occuring numbers of hydrocarbon-degrading microorganisms are low.","PeriodicalId":75751,"journal":{"name":"CRC critical reviews in microbiology","volume":"5 4","pages":"371-86"},"PeriodicalIF":0.0,"publicationDate":"1977-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/10408417709102810","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11546748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
