For a long time, probiotics have been widely used as safe microorganisms that can confers a health benefit effects on the host, directly or indirectly. Recently, postbiotics have gained interest as new health promoters. Postbiotics have recently been defined as complex mixture of functional bioactive compounds secreted by probiotics during a fermentation process (such as biosurfactants, proteins, short chain fatty acids, organic acids, bacteriocins, vitamins etc.). According to current data, postbiotics have advantages over live probiotics with regard to: ease extraction, standardization, and storage, availability for industrial-scale-up, specific mechanism of action, impossible to transfer and acquire antibiotic resistance genes and their interaction with the cellular receptors to trigger the targeted responses. However, several aspects related to postbiotics have not been fully elucidated. Here, we provided a critical review of the postbiotic definition, mechanisms of action, underlying their beneficial effects, as well as current trends for applications in foods and pharmaceuticals.

Climate change represents one of the greatest environmental challenges of the 21st century, accentuated by deforestation and the degradation of habitats. Changes in vital aspects such as temperature, the amount and distribution of rainfall or the frequency of extreme meteorological phenomena will probably negatively affect ecosystems. The possibilities of invasion will predictably increase, being endemic species especially vulnerable to the effects of climate change. Invasive species are extremely adaptable to climate variability, as evidenced by their current large latitudinal ranges. Generally, invasive plants also have rapid dispersal characteristics, allowing them to vary their ranges in response to changing climatic conditions rapidly. As a result, these species could become more dominant in many areas under changing climatic conditions. In many situations, the environmental stress generated by climate change and invasive plants are synergistic: invasive species can exacerbate the impacts of climate change on ecosystems, and in the same way, climate change can allow new invasions.

The present study aimed to evaluate the potential of a Pseudomonas aeruginosa strain to tolerate and degrade aliphatic petroleum hydrocarbons. P. aeruginosa IBBCt8 was isolated from a seawater sample using crude oil as the sole carbon source in a minimal medium. The bacterium was identified as P. aeruginosa based on its morphological, biochemical, and molecular characteristics. P. aeruginosa IBBCt8, which possesses alkB (870 bp) and rhlAB (216 bp) genes in its genome, showed a higher tolerance and degradation efficiency of the n-hexadecane, n-decane, cyclohexane, or paraffin oil, compared with the tolerance to n-hexane and its degradation. P. aeruginosa IBBCt8 cells produced rhamnolipid biosurfactants which showed a very good emulsification activity against the tested aliphatic hydrocarbons. Due to its characteristics, the isolated bacterium could be used in the bioremediation of petroleum-polluted environments.

Antibiotic resistance of Staphylococcus is increasing worldwide and is becoming a global concern. The present report exposes the study of the antibiotic susceptibility in isolates of Staphylococcus spp obtained from farm pigs. The samples were collected from healthy pigs, from different farms, in the period between 2019-2020. Forty strains of Staphylococcus were isolated from the anterior nares of individual pigs, and from the skin behind the ears of the animals. These isolates were tested against 12 different antimicrobial agents using the Kirby-Bauer disk-diffusion method. The antibiotic susceptibility profile of different bacteria isolates was studied to detect MAR, MDR. Multiple antibiotic resistance (MAR) indices were determined and it was above 0.2 in 24 of the total of 40 bacteria studied. The highest MAR index was detected in Staphylococcus lentus (0.5) and Staphylococcus xylosus (0.41) and 26 (65%) strains was MDR. In conclusion, the high levels of antibiotic resistance generally correlates with high antibiotic usage and antibiotics used are a risk to humans with occupational contact with livestock antibiotics.

Weight-length relationships (WLRs), Fulton’s K condition factor and the size structure were investigated for common carp Cyprinus carpio (Linne, 1758) collected from Bițina 3 Pond – a freshwater ecosystem used for recreational fishing, located 40 km away from Bucharest. Negative allometric growth was estimated for common carp as: TW = 0.0563xTL2.7111; TW = 0.2301 x SL2.4175 (N = 30, November 2021). The values for condition factor K ranged between 1.44 and 2.67. Water samples were collected from 7 sampling points (SP) and were subjected to physico-chemical characterization. Consequently, it was determined the following parameters: pH, electrical conductivity (EC), total hardness (TH), chemical oxygen demand (COD), phosphate phosphorus (P-PO43-) and nitrogen pollutant species: nitrate nitrogen (N-NO3-), nitrite nitrogen (N-NO2-) and ammonium-nitrogen (N-NH4+). Total hardness values present very significant correlation with conductivity (r=0.7305***) and distinct significant correlation with pH (r=0.5765**). The results indicated that water meets the requirements for optimal development of aquatic organisms. This paper provides novel information on weight-length relationships, Fulton’s K condition factor along with environmental parameters for Cyprinus carpio collected from freshwater ponds designed for sport fishing.

Strawberry is one of the most commonly cultivated and consumed plant, due to its organoleptic properties and nutritional values, exerting multiple beneficial health effects. In this study, two distinct strawberry callus lines obtained in different lighting conditions were characterized. The biotechnological potential of these cultures can be demonstrated by biomass and secondary metabolites accumulation. For this reason, growth rate, cellular morphology and viability were assessed. For metabolic potential evaluation, biochemical analyses of total phenolic and flavonoid content, anthocyanin pigments concentrations and antioxidant capacity were performed. The red callus line displayed higher growth rate, total phenolic content and antioxidant activity than the white line. Flavonoids and anthocyanins were present only in the red line. The biomass and these metabolites accumulation varied between subcultures, but were maintained at a high rate, being superior to values reported in planta. Our results show that both callus cultures lines were highly proliferative and the red one being a source of valuable bioactive secondary metabolites, with high antioxidant activity.

This paper aimed to analyze the variability of spring phenophases in the apple species, the 'GoldRush’ cultivar to analyze the risk of spring frost for apple production in Stănești area of Argeș County (45°13′44″N, 24°50′9″E, altitude 540m), Romania, and the role of phenological acclimatization. The timing of phenological stages is made according to the definitions of the Biologische Bundesanstalt, Bundessortenamt, and CHemical industry (BBCH). Based on Julian day number, on average for 4 years, the phenophases occurred from the 85.54 day of year, marked by “beginning of leaf bud swelling/inflorescence bud swelling” (BBCH 01/51), until 1the 23.36 day of year for phenophase "end of flowering" (BBCH 69). Analyzing the data obtained, they allowed us to assess the temporal trends of development of budding and flowering phenophases and the trends of risks in the light of global warming. The research will be continued in order to analyze a longer period of time and to analyze different cultivars, in order to achieve sustainable and competitive fruit crops.

In this research the screening of several higher fungi - basidiomycetes cultures for the presence of collagenolytic activity was carried out. The highest collagenase activity was detected in submerged culture of higher fungus Coprinus lagopides. The enzyme preparation of collagenase was isolated from culture liquid of this producer. The optimum temperature and pH of the collagenolytic activity of the enzyme preparation were determined. The selection of nitrogen and carbon sources and ratios of carbon and nitrogen sources in the composition of nutrient mediums was carried out in order to increase the collagenase activity of fungus submerged culture. In addition to the collagenase activity of producers culture the amount of accumulated biomass, pH and protein concentration in the culture liquid of basidiomycete were also determined.

The article presents the results of research on potato varieties in the Polissia zone of Ukraine. According to them, the adaptive potential, phenotypic stability and resistance to stressful environmental conditions were calculated based on the "yield" feature. According to the results of a comprehensive assessment, it was established that the general adaptive capacity according to the absolute coefficient of adaptability is characteristic of the following varieties: Prada, Sanibel, Riviera, Vzirets, Bellarosa, Zhytnytsia, Rodynna, Lilly, Yavir, Knyazha, Sluch, Toscana, Challenger. High stress resistance was found in potato varieties: Prada Predslava, Challenger. Genetic plasticity, which has a high degree of compatibility of the "genotype-environment" factors, was established in the varieties: Prada, Sluch, Bellarosa, Rodinna. According to the coefficient of variation, a high degree of variation (variability) was established in the varieties: Sluch, Vzirets. Varieties: Prada, Challenger, Predslava had slight variability. This assessment will contribute to the selection of potato varieties for profitable and economically profitable potato farming.
