Azov shad ( Alosa tanaica , Grimm 1901) is a marine anadromous species, which migrates for spawning from sea into fresh water lakes and rivers. It winters in the sea and appears close to shore in spring when the water temperature reaches the value of approximately 6 degrees Celsius. The paper presents the biological parameters such as length and weight class structure, age, sex ratio and degree of maturation of the commercial fish Azov shad belonging to the family Clupeidae . The investigations were performed during 2014 on fish caught along the entire Romanian coast from Sulina to Vama Veche. The study of the behaviour of Azov shad (reproduction, migration, feeding) is important to understand the impact on populations and to find sustainable solutions to manage these aspects. The preference for certain areas of distribution, for feeding and breeding was determined by analysing samples collected by passive fishing (shad gillnets set in all fishing points across the Romanian Coast). The main aim of this research is to identify the current state of Azov shad population along the Black Sea Coast considering that its biology and conservation are less known. Â

Abstract. The availability of hares (Lepus europaeus Pallas), unlike that of domestic rabbits, is restricted by hunting seasons. Rabbit meat, according to research from Spain, is a rich source of K, P, Fe and Mg, but poor in Na, being recommended for people with hypertension. The largest quantity of macro minerals studied in rabbit meat was determined for K and P, and the most abundant micro minerals were Zn, Fe, Cu and Mn. In hare meat, ash content is not sufficiently studied. The current low level of knowledge motivated the present study. The aim of this study was to establish the ash content for major muscle groups and edible offal of hares. The biological material used was collected from 49 hares with an average weight of 5.6 kg, at the age of reproductive maturity (adults: 11-12 months). Different muscle groups (the muscles Cervicalis, Intercostalis, Longissimus Dorsi, Psoas major, Triceps Brachi, Biceps femoris, Semimembranosus ) and the main edible offal (heart, liver, kidney) were sampled. The ash was determined by calcination (in Supertherm C311 oven calcination) at 550 0 C. The results obtained were interpreted statistically (arithmetic mean (X), standard deviation (s), variance (s 2 ) and coefficient of variation (V%) and the statistical significance of differences was tested using the ANOVA Single Factor algorithm (p>0.05; p<0.01; p<0.001). Ash content for the main muscle groups analysed varied from the lowest average values of 1.095% for the Intercostalis muscles, to the highest average values of 1.256%, for Triceps brachii muscles.

Abstract Polymers are a common choice as protective materials since they combine flexibility, variable sizes and shapes, relatively light weight, stability, resistance to breaking, barrier properties and perceived high-quality image with cost-effectiveness. Currently, mainly non-biodegradable petroleum-based synthetic polymers are used as packaging materials for foods, because of their availability, low cost and functionality. However, biopolymers can be made from renewable resources without the environmental issues of petroleum-based polymers and with the additional advantage of being available from renewable sources or as by-products or waste-products from the food and agriculture industries. The aim of this study was to test some food packaging biopolymers based on PVA. In this respect, some biopolymers for food packaging applications were subjected to biodegradation tests by covering the tested samples with soil. The samples were incubated in known temperature and humidity conditions. The experiment lasted 45 days, after that the samples were washed, weighed and the biodegradation degree was calculated. The obtained results shows that PVA is a promising material for food packaging usage, as it is made from renewable resources and it is environmentally friendly. Â

Due to the fact that meat colour represents an important aspect for sensorial evaluation of any food product,research in the field of poultry meat processing regarding efficient methods for hoarding/storage on long term ofindustrially slaughtered poultry carcasses approaches a continuous finding/optimization of certain solutions foravoiding negative consequences due to oxidation, which could include colour loss and/or its modification.The current study aimed to evaluate the effects of three storage regimes differing by temperature and time(L = -14°C, 30 days; L = -16°C, 60 days; L = -18°C, 90 days) on three anatomical cut regions (breast, upper thighand lower thigh), to characterize the colour of broiler chicken meat. Objective description of colour for frozen anddefrosted chicken meat was realised through the CIEL*a*b* Cartesian coordinate system.Overall, the preservation method determines a higher luminosity at samples gathered from L batch chickencarcasses for breast and upper thigh musculature, and L for lower thigh musculature in comparison with thecounterparts from the other experimental batches

Bioremediation has received a great deal of attention, and bacteria isolated from polluted soil can be usedin that process. In this study, we performed an evaluation of the physiological groups of microorganisms fromsoil contaminated with petroleum. Bacterial strains were isolated from contaminated soil using the selectiveenrichment technique. Minimal Salt Media was used for serial dilutions to determine viable cell count. Thenumber of total viable cells and different types of microorganisms in the original sample was determined by serialdilution, agar plating procedure using selective media. The plates were incubated at 300C for 24-72 hours. Distinctcolonies growing on each plate were selected, and stored at freezing temperatures. The bacterial colonies werethen identified by Gram staining and biochemical tests. Following our research, it was observed that although thetotal microbial load of soil is relatively close in value, there are differences regarding the physiological group ofmicroorganisms. In the oil contaminated soil sample the largest group of microorganisms was the nitrous nitrifyingbacteria followed by nitrate bacteria. All bacterial strains that were isolated from soil samples contaminated withhydrocarbons but also the Pseudomonas putida and Bacillus subtillis strains can use diesel fuel as a food source.With the increase of diesel fuel concentration from culture medium, the majority of the bacterial strains that wereused in our experiments showed an increased value of absorbance. This fact suggests that these strains can be usedin bioremediation processes. Â

Royal jelly has become a high-value commercial product and the standardization of this product is required to guarantee its quality on the market. The objective of the research activity was to pursue the chemical composition of commercial samples of Royal Jelly in Romania in order to propose standardization for this product. The physico-chemical composition of commercial Royal Jelly samples was analysed by determining quality parameters like: carbohydrates, lipids, proteins, 10-hydroxy-2-decenoic acid (10-HDA) and mineral elements. Carbohydrates analysis showed values between 3.4 % and 5.87 % for fructose, 4.12 % and 7.05 % for glucose, while for sucrose the values ranged between 0.95 % and 2.56 % (determined by HPLC-RI). The lipids content ranged between 1.85 % and 6.32 % (determined by the Soxhlet method). The protein values extended from 13.10 % (RJ2) to 17.04 % (RJ10) (the total protein content was determined by the Kjeldahl method). The values for the major fatty acid in Royal Jelly, 10-HDA, ranged between 1.35 % (RJ8) and 2.03 % (RJ10) (determined by high-performance liquid chromatography). The concentration of minerals varied between 3188.70 mg/kg and 4023.39 mg/kg (the concentration of minerals was measured using flame atomic absorption spectrometry). Potassium, followed by magnesium, sodium and calcium, occurs in the highest concentrations. The commercial Royal Jelly samples analysed presented variable physico-chemical characteristics that correspond with the values given by international quality standard proposals for Royal Jelly.

Mare’s milk is similar to human breast milk and has valuable therapeutic properties. For this reason, Europeans are increasingly interested in discovering its benefits and how the chemical composition of horse milk differs from that of other species. This interest is reflected in the number of new farms selling mare’s milk around the world as this milk is the most similar to human milk. Mare’s milk is considered to be highly digestible, rich in essential nutrients and whey protein, which makes it very suitable as a substitute for bovine milk in paediatric diets. During the period of lactation, mammal's milk composition is subject to rapid changes in macro- and micro-elements, as well as in the quantity and quality of proteins, lipids and saccharides, being ideal food for infants. The primary use of mare’s milk has been the rearing of foals, but recently, due to the similarity of its chemical composition to that of human milk, it has raised particular interest and some experiments have been done to apply it as a raw material for the preparation of special food products for human consumption. Mare’s milk products are very common in Russia and Central Asia throughout Mongolia. In the 19 th century, some Russian scientists explored its therapeutic properties and then in 1859 they founded the first sanatorium where treatments with mare’s milk could be made under medical control. Due to its potential health-promoting characteristics, in the Western countries, interest in mare's milk has lately increased. Â

One of the main objectives in dairy cows exploitation is to guarantee food security and safety of the population, a desideratum achieved through better milk quality and better control of production in all aspects imposed by the health and welfare of animals from which milk is obtained. The purpose of this sciencific paper is to highlight the status of mammary gland health in a population of Friesian-Black Spotted breed based on the main traits of milk quality, with particular reference to somatic cell counts as the main indicator of subclinical mastitis. The research was conducted in 2014 within the farm S.C. “Modern Farm†S.R.L., located in Jucu village. The individual analysis of Holstein Friesian milked cows was performed, the main indicators of milk production were analysed both quantitatively, based on production obtained daily, and especially qualitatively, based on seven controls with individual sampling from all milked cows at the date of control. Qualitative analysis of 1,391 milk samples highlighted the fact that the somatic cell count in milk obtained from cattle included in this study  recorded an average value of 390.54 ± 11.16 cells/ml x 10 3 with the variability between controls of 314.94 ± 28.93 and 482.36 ± 91.12 cells/ml x 10 3 . Regarding the fat content, the average values was 4.19%, 3.63% for protein content, a pH value of 6.56 and the values of  urea was 20.09 mg/dl. Individual analysis also revealed some cows with subclinical mastitis, which were milked separately, verified and monitored supplementarily in order to reestablish udder health and to prevent the occurrence of clinical mastitis, which can compromise the mammary gland.

In this study polyphenols content and antioxidant activity of melliferous plants for the following: mint ( Mentha pulegium) , burdock ( Arctium lappa), comfrey (Symphytum officinale), plantain (Pantago lanceolata), thyme (Thymus vulgaris), sage (Salvia officinalis), marigold (Calendula officinalis) , small marshmallow (Althaea officinalis), echinacea (Echinaceea angustifolia) and black popular (Populus nigra) were investigated, using two different extraction methods. High content of polyphenols and flavones were extracted from Populus nigra , with an average of both extractions 23.14 mg GAE/g and 78.07 mg QE/g flavones. Among the studied plants, Arctium lappa registered the highest antioxidant activity (0.129 mmol Trolox/mL) in alcoholic extract and Echinaceea angustifolia with a value of 0.122 mmol Trolox/mL in aqueous extract. The lowest values were recorded for the antioxidant activity of Althaea officinalis (alcoholic extract) and Arctium lappa (aqueous extract). The results show that Arctium lappa, Echinaceea angustifolia and Populus nigra can be considered melliferous plants for their high biologically active compounds potential and bee products (honey and pollen) that having the composition of these plants will have high antioxidant and antibacterial properties.

The Romanian Buffalo Breed (RBB), established in 1987, originated from local river buffalo populations highly adapted to the low-input breeding condition. Cross-breeding with Asian breeds was recently used for genetic improvement in milk production. In the last 25 years the species has dramatically decreased. Over 90% of livestock has been sold and never replaced. The population is now mainly maintained in subsistence farms. This study aims to assess the genetic diversity within the remaining population and to verify links with improved breeds supposedly introgressed in RBB. To assess the genetic diversity of RBB and ascertain possible phylogenetic relations with other buffalo breeds, we sequenced the entire cytochrome B gene (MTCYB) in a sample population. Blood samples were collected from randomly selected 52 unrelated individuals from various locations in Transylvania. A DNA fragment containing the entire MTCYB gene (1140bp) was amplified by PCR directly from whole blood (1μl). The amplicons were sequenced using two pairs of primers. The sequences were subsequently used for genetic diversity assessments. Analysis of the sequences led to the identification of five novel MTCYB haplotypes, uploaded in GenBank with the following accession numbers: JQ241279; JQ241280; JQ241281; JQ241282; JQ241283. In the sample population, the most frequently identified haplotypes were haplotype 2 (EF409940.1) and haplotype 3 (EF409941.1), previously reported in other buffalo populations, mainly from Asia, confirming the Asiatic origins of RBB. Sequence comparisons have revealed that RBB is mainly related with Indian breeds. Despite the numerical decline of RBB, through correct breeding schemes the breed maintained a good level of genetic diversity. Our analysis confirms RBB’s Asiatic origins. Presence of new haplotypes may also reflect that this population is isolated from a geographical and reproductive point of view.
