Antimicrobial Activity Of The Macrofungus Coriolus Versicolor(L. Ex Fr.) Quel, Başaran Dülger, Ümi̇t Arslan
Turkish Journal of Biology
In this study, ethyl acetate, acetone, chloroform and ethanol extracts of Coriolus versicolor (L. ex Fr.) Quel. were tested for antimicrobial activity by Disc Diffusion method on the following test microorganisms: Aeromonas hydrophila ATCC 7966, Listeria monocytogenes ATCC 19117, Escherichia coli ATCC 11230, Enterobacter aerogenes ATCC 13048, Corynebacterium xerosis CCM 2824, Corynebacterium glutamicum ATCC 13022, Proteus vugaris ATCC 8427, Serratia marcescens NRRL 3284, Bacillus cereus ATCC 7064, Bacillus subtilis ATCC 6633, Bacilus brevis ATCC 9999, Bacilus sphaericus, Bacillus megaterium DSM 32, Mycobacterium smegmatis CCM 2067, Sarcina lutea, Micrococcus luteus LA 2971, Staphylococcus aureus ATCC 6538P, Stapylococcus epidermidis NRLL B-4887, Alcaligenes …
Effect Of Dietary Fatty Acids And Starvation On The Fatty Acidcomposition In The Muscle Tissue Of Cyprinion Macrostomusheckel, 1843, M. Ali̇ Akpinar
Effect Of Dietary Fatty Acids And Starvation On The Fatty Acidcomposition In The Muscle Tissue Of Cyprinion Macrostomusheckel, 1843, M. Ali̇ Akpinar
Turkish Journal of Biology
Variations in the fatty acids compositions of muscle tissue, due to starving and feeding Cyprinion macrostomus (Heckel, 1843) at 35 and 24°C which naturally lives at 35±0.5°C in the Kan-gal Thermal Spring (Sivas) were investigated. No qualitative variation took place in the fatty acid composition of the fish which were fed and star-ved at 35°C. As far as the fish which were fed and starved at 24°C were concerned, it has determi-ned that docosapentaenoic acid (C22:5) and docosahexaenoic acid (C22:6), which are not found in fo-od could be synthesized and linoleic acid (C18:2) percentage was drastically decreased. According to the …
Variation Of Total Lipid And Fatty Acid Amount And Compositions Inmuscles Of Capoeta Trutta And Barbus Rajanorum Mystaceus Duringreproduction Period, Vahi̇t Konar, Ayhan Canpolat, Ökkeş Yilmaz, Feri̇t Gürsu

Turkish Journal of Biology
In this study, the variation of total lipid and fatty acid composition in muscle tissues of females and males of Copoeta trutta and Barbus rajanorum mystaceus living in Keban Dam Lake (Elazig) were examined. It was observed that the amount of total lipid in muscle tissues of C. trutta (p
Investigation On The Isolation And Identification Of The Listeria Species In The White And Civil Cheeses Purchased From Erzurum Region, A. Aydan Kara, Ömer Faruk Algur, Mükerrem Kaya
Investigation On The Isolation And Identification Of The Listeria Species In The White And Civil Cheeses Purchased From Erzurum Region, A. Aydan Kara, Ömer Faruk Algur, Mükerrem Kaya
Turkish Journal of Biology
In this study, 34 white cheeses and 16 civil (local name) cheeses purchased from markets and shops in Erzurum during the period of January 1995-April 1996 were analysed. The samples were streaked directly onto LSA and Palcam Agar media in Petri Plates and incubated at 37C° for 48 hours. After the incubation, the growing colonies on LSA-agar plates were examined by Henry's Modified IIIumination Method while collonies on Palcam agar were examined by naked eye. Typical colonies were selected and used for several biochemical tests. As a result, it was found that only one sample (2.94%) of the white cheeses …
Field Sampling And Necropsy Examination Of Fish, A. S. Kane, A. Baya, R. Reimschuessel, K. M. St. Pé, C. A. Poukish, C. P. Driscoll
Field Sampling And Necropsy Examination Of Fish, A. S. Kane, A. Baya, R. Reimschuessel, K. M. St. Pé, C. A. Poukish, C. P. Driscoll
Virginia Journal of Science
This paper presents an overview of observational and fish sampling techniques for investigating fish lesions, morbidity and mortality. These sampling techniques and investigations are much like detective work and require attention to detail, common sense, technical proficiency and experience. To solve the mystery of a fish kill, the investigator must use available evidence and clues to piece together a series of events that often have long since passed. The cause of these field events may be chemical, biological or physical; more often, it is some combination of these. An initial categorization approach may be used to reduce the great number …

Virginia's Pfiesteria Monitoring Program: Water Quality, Roger K. Everton, Wick T. Harlan, Jonathan W. Priest, Mark S. Alling
Virginia Journal of Science
During the summer and early fall of 1998, 34 estuarine stations in Virginia were sampled for Pfiesteria like organisms (PLOs) and associated water quality conditions. Stations were sampled either bimonthly (20 stations) or monthly (14 stations) from June to October 1998. At each station, a set of live and Lugol' s preserved samples were collected for presumptive counts of PLOs and water quality conditions were determined. Water quality parameters measured included standard field parameters, nutrients (total, dissolved, and particulate), chlorophyll a, and conventional water quality indicators. Although PLOs were relatively low in 1998 as compared to 1997, presumptive PLO counts …

Turkish Journal of Biology
The aim of these studies is to analyze, by immunohistochemical methods, the emergence and distribution of vimentin and desmin in stromal cells of rat endometrium in early pregnancy and determine their role in decidualization and implantation biology. For this purpose totally 1-8 days pregnant 64 female and 32 male rats were used. On first day of pregnancy vimentin and third day of pregnancy desmin were staining respectively in the endometrial stromal tissue of rat. Although vimentin was seen during the early pregnancy, following the day 5 of pregnancy when the implantation begins interestingly desmin was only located in the antimezometrial …
A Study Of Pollen Mitosis And Pollen Morphology Inhexaploid (2n=24) Bellevalia Edirnensisözhatay & Mathew, Feruzan Dane
A Study Of Pollen Mitosis And Pollen Morphology Inhexaploid (2n=24) Bellevalia Edirnensisözhatay & Mathew, Feruzan Dane
Turkish Journal of Biology
: The pollen mitosis and pollen morphology of hexaploid (2n=24) Bellevalia edirnensis Özhatay & Mathew were examined. Microspores exhibited variation in size, and the exine and aperture developed before pollen mitosis began. During pollen mitosis, polarization, asymmetric styles and normal divisions were observed together with some abnormalities. During polarization of the microspore both nucleus migration and vacuole formation were common. The generative nucleus was in the proximal pole and the vegetative nucleus was in the distal pole. It was also determined that the mature pollens were 2-celled, the shape of the pollens was sphaeroidea, the type of the pollens was …
