Effects Of Source And Concentrations Of Nitrogen And Carbohydrate On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell

Turkish Journal of Veterinary & Animal Sciences

The objective of this review was to discuss microbial protein synthesis and the effects of sources and concentrations of nitrogen and carbohydrate on microbial protein synthesis. Even though ammonia-N is a satisfactory source of nitrogen for the growth of the majority of rumen microbes, substitution of intact protein for urea usually stimulates ruminal microbial protein synthesis. While protein sources high in degradable intake protein (DIP), such as soybean meal, appear to have properties that optimize microbial protein synthesis, protein sources low in DIP, such as fish meal, appear to limit microbial protein synthesis apparantly because of the low ruminal digestibility …

Transformation And Stability Of Cloned Polysaccharidase Genes In Gram-Positive Bacteria, Mehmet Sai̇t Eki̇nci̇, Harry J. Flint

Turkish Journal of Veterinary & Animal Sciences

Polysaccharidase genes from rumen bacteria were transferred to and expressed in ruminal and non-ruminal Gram-positive bacteria. The transformation efficiency and genetic stability of polysaccharidase genes in bacteria from different habitats were investigated. PCR amplification of cloned polysaccharidase genes from Escherichia coli, Lactococcus lactis, Enterococcus faecalis, Streptococcus sanguis and S. bovis strain 26 showed that rearrangement of plasmid and the gene fragment did not occur. The DNA band sizes from all primers agreed with the expectations of some transformants of S. bovis JB1 being rearranged. In spite of the rearrangement in S. bovis JB1 polysaccharidase activities were conserved. Growing in the …

The Application Of Hypoxanthine Activity As A Quality Indicator Of Cold Stored Fish Burgers, Sühendan Mol, Nuray Erkan, Candan Varlik

Turkish Journal of Veterinary & Animal Sciences

Seafoods are very perishable, and many different methods are used for the determination of their quality. Sensory and hypoxanthine values of cold stored trout burgers, which we prepared, were determined during a 28-day period. Burgers spoiled after the 21st day of storage. The TVB-N values were still very low when the burgers spoiled and the pH values decreased during their storage. Therefore total volatile bases nitrogen and pH analyses were not useful for the determination of the quality of trout burgers. There was a negative correlation between the sensory and the hypoxanthine values during the storage period. Thus, hypoxanthine analysis …

Mono And Multiphasic Analysis Of Growth Curves Selected Of A Japanese Quail Line At 5-Week's Body Weight, Handan Çamdevi̇ren, Bahar Taşdelen

Turkish Journal of Veterinary & Animal Sciences

In this research, monophasic, diphasic and triphasic logistic growth curve functions used to introduce the growing of the body weight in Japanese quail (Coturnix japonica) are presented. In male and female Japanese quail, the diphasic growth curve fits better than the other growth curves because of residual variance, autocorrelation and determination coefficients. In addition, the diphasic growth function is compared with the monophasic growth function to study the relationship between these two approaches for describing growth curves.

The Need For Confirmation In Coliform And E. Coli Enumeration In Foods, İbrahi̇m Çakir, Hi̇lal B. Doğan, Ensar Başpinar, Fi̇kret Keven, A. Kadi̇r Halkman

Turkish Journal of Veterinary & Animal Sciences

For food and environmental analysis, coliform bacteria and especially E. coli should be determined and enumerated rapidly, correctly and economically. Even if the results are obtained either by traditional or improved techniques, the results require confirmation, meaning that these techniques are not reliable. Confirmation tests need additional time and/or cost. In this study, 500 food samples of 10 various types were analyzed for their natural coliform contamination by the standard MPN method and E. coli by two MUG based MPN techniques. Enumeration results were statistically analyzed to determine whether confirmation tests for coliform and E. coli analysis are necessary or …

Characterisation Of An Exopolysaccharide Preventing Phage Adsorption In Lactococcus Lactis Subsp. Cremoris Ma39, Mustafa Akçeli̇k, Pinar Şanlibaba

Turkish Journal of Veterinary & Animal Sciences

Lactococcus lactis subsp. cremoris strain MA39 produces an extracellular polysaccharide containing rhamnose, glucose and galactose. A 16.5 kb plasmid encoding exopolysaccharide production in MA39 was determined by plasmid curing experiments. Phage adsorption assays showed that four different lactococcal phages were adsorbed to MA39-40; only the 16.5 kb plasmid cured an exopolysaccharide non-producing mutant of strain MA39, with high efficiency (93.2-98.5%) while adsorption of these phages was completely inhibited in the wild type strain MA39. These results suggest that exopolysaccharide prevents phage adsorption by masking phage receptor sites.

Suitability Of Hsp70 As A Biomarker For Pesticide Contamination Of Aquatic Systems: A Laboratory Investigation Using Chironomus Tentans As A Model, Lori Rae Covington

Dissertations and Theses @ UNI

Though the use of pesticides has resulted in increased crop production and other benefits, concerns have been raised about potential adverse effects on the environment, especially the hydrologic system which supports aquatic life. To chemically analyze for all possible contaminants at all at-risk sites would not only be costly, but practically infeasible and would yield no information about biological effects. Therefore, a significant portion of the scientific community has turned their investigative focus to biomarkers as a measurement of sublethal contaminant exposure and effect. A biomarker that has been the recent focus of much research is the family of heat …

Shrimp Adjust Their Sex Ratio To Fluctuating Age Distributions, Eric Charnov, Robert Hannah

Biology Faculty & Staff Publications

Long-term data sets that quantitatively confirm basic ecological theory are rare for field populations. Highly variable recruitment often causes wide temporal variation in population age distribution and basic theory for adaptive sex ratio often predicts sex ratio tracking' to match the fluctuating age distribution. Using sex-changing shrimp as a model system, we test this in a new data set of 20 years duration. The new data support the theory, despite intense fishery exploitation that itself has greatly altered the age distribution in recent years.

Reproductive Effort, Offspring Size And Benefit/Cost Ratios In The Classification Of Life Histories, Eric Charnov

Biology Faculty & Staff Publications

There have been many attempts to document links between reproductive allocation and factors such as adult body size and demography. This paper suggests that among closely related taxa, two dimensionless numbers, each a benefit—cost ratio summarizing reproductive timing, allocation and demography, are invariants and thus are useful to classify life histories. The two numbers are E/α and C·E, where E is average adult life span,α is age-at-first-reproduction and C is average mass (per adult) devoted to reproduction per unit of time, divided by the average adult body mass (m); C is usually called reproductive effort'. Since E−1 is the average …
