Abstract: Individual minerals and antibacterial activity were investigated in 5 medicinal plants (pot marigold - Calendula officinalis, burdock - Arctium lappa, celandine - Chelidonium majus, basil- Ocimum basilicum, thyme - Thymus vulgaris) using Atomic Absorption Spectroscopy (AAS) technique and antibiogram method. The antibacterial susceptibility has been evaluated over 12 strains isolated from milk microflora, belonging to Staphylococcus, Vibrio, Serratia and Bacillus genera. The obtained results show the best antibacterial effect with Arctium lappa ethanol extracts, having inhibition areas of 6.3 to 17.5 mm, with an average of 9.0 mm and the highest determined mineral being Calcium. The results obtained open the prospect of using these medicinal plants as an alternative to be used for the control and cure of some mineral deficiencies or for preventing various diseases of the animals.

Abstract: Honey is used for centuries both as nutrient and in medicine, being an exhaustless source of benefic factors for health and also for different biotechnological processes. This is a complex matrix which possesses antioxidant and antimicrobial properties due to its peroxidic activity and bioactive compounds. A fully validated approach for the determination of sugars, hydroxymethylfurfural content and diastase activity in honey samples were presented in accordance with the official methods from the International Honey Commission. Spectrophotometric method was used for diastazic activity determination and chromatographic determinations for HMF content (photodiode array detection) and sugars (refractive index detection). The limits of detection and quantification were calculated. Accuracy, precision and uncertainty were determined in the spectrophotometric and chromatographic techniques using the certified reference material. Diastase activity, sucrose content and hydroxymethylfurfural (HMF) content were easily differentiated and these parameters were used for indication of a possible adulteration of the honey. The present study confirms that, in order to have an authentic honey sample, diastazic activity must be above 8 DN (diastazic number) and HMF content less than 40 mg/kg. Sugar spectrum is different for every honey type. Consequently, physico-chemical analysis should be combined for the determination of authentic honey and proper labeling.

Abstract: Beebread is a valuable bee product, both for bee nutrition and for humans. The high nutritional and bioactive properties of beebread were evaluated by chemical composition analysis of beebread from Apis mellifera and Apis dorsata. Bee bread harvested from Romania and India, coming from Apis mellifera and Apis dorsata bees, were evaluated for their chemical composition. Analyses were made in APHIS Laboratory from USAMV Cluj, using validated methods for bee products. Lipids were determined by the Soxhlet extraction method, total protein content was determined by Kjehldahl method, sugar spectrum was determined by high performance liquid chromatography with refractive index detection (HPLC-IR). Water content of beebread samples were situated between 11.45 and 16.46%, total protein content between 16.84 and 19.19% and total lipids between 6.36 and 13.47%.Â Beebread has high bioactive properties which can be expressed as antioxidant and/or antibacterial activity. Chemical composition and bioactive properties of beebread is influenced by floral origin of the pollen which the bees collect and place in combs for fermentation. Also the climatic conditions have an important role in developing different fermentation compounds, that may act as antioxidants or antibacterial agents.

Abstract: Given their beneficial effects in terms of health, the natural products, especially beehive products, have drawn the attention of consumers since long time ago. In order to guarantee the quality of these products on the market, their chemical composition needs to be analyzed. Thus, this current research had as objective the establishment of quality parameters for beehive brood food derived products: apilarnil and queen bee larvae triturate. These two products were compared with royal jelly which is the basis of brood food in the first 3 days of larval stage. The carbohydrates were determined by HPLC-IR and allowed the identification of seven carbohydrate compounds, predominantly glucose, fructose and sucrose. The lipid profile was analyzed by the Soxhlet method. The total protein content was determined by the Kjeldahl method. Free amino acids were analyzed by LC-MS. A total of 31 amino acids were identified of which nine are essential amino acids for humans.Â

Abstract: The Global Centre of Excellence for Advance Research in Sericulture and Promotion of Silk Production (GCEARS-PSP), recognised by ISC since 2014, was created with the main purposes: development of advanced research in sericulture and diagnostic services using modern techniques, achievement of a gene pool of different silkworms races and promotion of silk production. The objective of this study was to characterize the races from the GCEARS-PSP, in order to conserve the most valuable and resistant ones. This characterisation is a part of GCEARS-PSP’s strategy for the revival and development of sericulture and silk production in Romania. The GCEARS-PSP represents an important point of reference for Romanian sericulture. The experimental data described showed a good prospective for a proper functioning of the research centre and the obtained results are promising for the next lines of research.

Abstract: Bee-pollen was used for thousands of years as functional food and medicinal plant product. Various beneficial effects were attributed to it and its consumption was increased over the years. The tests have been made on 16 pollen samples of the following families: Rosaceae, Salicaceae, Fabaceae, Tiliaceae, Asteraceae, Brassicaceae and two polifloral pollen assortment, using difuzimetric method. Among the tested bacteria, the Onobrychis viciifolia pollen has the highest sensitivity 11.86±1.79 mm while the low antibacterial activity was registered for Brassica sp. pollen 8.65±2.65 mm. As the use of antibiotic substances over a long period of time resulted in larger doses of residues in milk and representing a potential biohazard, the use of ethanol extracts from beepollen is a real alternative in the treatment of cows with various diseases.

Abstract: Two microsporidia have been described infecting honey bees worldwide: Nosema apis and Nosema ceranae. The infecting forms of the parasite are the spores, ingested by the adult host insects. Studies demonstrated that the infection with Nosema spp. range from less than 1 to 100 percent, this disease reduces worker longevity by 22-44% which in turn reduces honey production and causes incomplete crop pollination. However, the used conventional drugs in beekeeping sector has a strong limitation due to the big concern about antibiotics resistance, transmission of antibiotics residues in beehive products and to a lesser extent, unbalancing risk of bee gut microbiota.This review highlights the importance to have healthy bee colonies, which implicitly lead to safety bee products. For this reason, orientation towards alternative treatments without antibiotics and based on natural products with higher antimicrobial effects it is very topical.
