There is a growing need for new formulations of carriers with better protection for bacterial inoculum. One of the newer techniques in inoculum making is encapsulation method. With this method, the whole bacterial cells are immobilized in defined space – matrix, where the cells are protected from environmental activities before use. Encapsulation of the inoculum was performed with ionic gelation method. The alginate-based microparticles (500-600 µm) containing viable B. japonicum strain were solidified in CaCl2. The initial number of viable bacteria in every sample was 9.0 log CFU/ml. Chitosan coated particles had a higher mortality rate than non-coated particles, with 1.3 log CFU/ml in lyophilized and wet microparticles stored at room temperature. High viability of B. japonicum was registered in wet particles stored at constant −20°C for thirty days with a viability rate of 8.84 log CFU/ml.

Young plants of celery, parsley, parsnip and carrot, grown in nutrient solution, were treated with sodium naphthenate (10−7 mol dm−3), applying foliar and root treatments. Both treatments affected the root content of all investigated elements present in the nutrient solution, but in a different way, depending on the plant species. An average change (increase/decrease) in the contents of investigated essential elements was about 35%. Our experiments with naphthenate showed that this treatment may enhance the efficiency of essential elements uptake and increase its content in plants without changing concentration of these elements in the nutrient solution. Especially interesting results were obtained in the case of carrot, as increased contents were observed in the elements that are usually deficient in nutrition (Fe, Zn, Mn), whereas the other remained unchanged.
Gastro-intestinal nematodes (GIN) of sheep are one of major constraints in grazing production systems worldwide. Control is commonly achieved using anthelmintics, but global occurrence of anthelmintic resistance to different drugs and the emergence of multi-resistant GIN species seriously limit the efficiency of their use. Therefore, integrated parasite management is widely recommended, with nematophagous fungi as one of control tools. Duddingtonia flagrans is one of the most used species, with various effect of different isolates. In previously performed coproculture assay, we showed low efficacy of D. flagrans MUCL 9827 against infective larvae (L3) of sheep GIN. The aim of current experiment was to reevaluate its nematophagous potential, using the medium where direct interaction between the fungus and L3 could be observed. Nematophagous activity was tested on 2% water agar with addition of chloramphenicol on three series of plates seeded with 500 and 1000 chlamidospores and agar blocks with 7 days old mycelium. At Days 0 and 5, 500 L3 of sheep GIN were added to test the trapping activity. The cultures, including control plates with only L3, were incubated at 25°C for 10 days, followed by evaluation of their number and reduction percentage. Nematophagous activity of D. flagrans MUCL 9827 against L3 was clearly demonstrated. However, the overall efficacy was poor since trapping was observed only in one out of nine plates containing fungal material. Potential reasons for such poor performance of the isolate of fungal species, otherwise known as successful in trapping animal parasitic nematodes, are discussed.
This study assessed the potential efficiency of selected biologically active substances on the motility behavior of rabbit spermatozoa subjected to in vitro induced E. faecalis contamination. Semen samples were collected from 10 male rabbits and the presence of E. faecalis was confirmed using MALDI-TOF Mass Spectrometry. For the in vitro experiments rabbit spermatozoa were resuspended in the presence of 0,3 McF E. faecalis and different concentrations of selected biomolecules (resveratrol - RES, quercetin - QUE, curcumin - CUR, epicatechin - EPI, isoquercitrin - IZO). Sperm motility was assessed using the computer-aided sperm analysis at 0h, 2h, 4h, 6h and 8h. The presence of E. faecalis significantly decreased the motility (P<0.001) when compared to the untreated Control starting at 2h and maintaining this negative impact throughout the entire in vitro culture. Meanwhile, the motility was significantly higher in the experimental samples subjected to E. faecalis together 5 μmol/L RES (P<0.05), 10 μmol/L QUE (P<0.05) as well as 1 μmol/L (P<0.01) and 10 μmol/L CUR (P<0.05) when compared to the Positive Control (4h). No biomolecule was able to maintain the motion comparable to the Negative Control, and none was effective against the rapid decline of sperm motility caused by the presence of E. faecalis during later stages of the in vitro experiment (6h and 8h). We may conclude that RES, QUE and CUR may provide a selective advantage to spermatozoa in the presence of E. faecalis, particularly during short-term rabbit semen handling.
