Chemical and biological properties of a sandy loam soil amended with olive mill waste, solid or liquid form, in vitro

Terbacil in concentrations up to 500 μg∙g−1 of sandy loam soil had little effect on populations of actinomycetes, bacteria, and fungi under laboratory and field conditions during a period of 5 mo. Concentrations up to 700 μg of terbacil∙mL−1 did not affect the in vitro growth of 111 strains of agriculturally important microorganisms, including effective, parasitic, and lysogenic rhizobia from seven cross-inoculation groups, pathogenic, attenuated, and saprophytic agrobacteria, azotobacters, and other bacteria, actinomycetes, and fungi. Terbacil inhibited the respiration of total soil microbiota, of bacteria, and of fungi at all concentrations tested. By contrast, it stimulated the respiration of actinomycetes at concentrations up to 500 μg∙mL−1 and partially inhibited it at 700 μg∙mL−1. Replication of bacterial and actinomycete isolates showed minimal inhibition by the extreme concentrations.

Cardiovascular toxicity remains one of the most adverse side effects in cancer patients receiving chemotherapy. Extra-virgin olive oil (EVOO) is rich in cancer preventive polyphenols endowed with anti-inflammatory, anti-oxidant activities which could exert protective effects on heart cells. One very interesting derivative of EVOO preparation is represented by purified extracts from olive mill waste waters, (OMWW) rich in polyphenols. Here, we have investigated the anti-cancer activity, of a OMWW preparation named A009 when combined with chemotherapeutics as well as its potential cardioprotective activities, Mice bearing prostate cancer (PCa) xenografts were treated with cisplatin, alone or in combination with A009. In an in vivo model, we found synergisms of A009 and cisplatin in reduction of prostate cancer tumor weight. Hearts of mice were analyzed, and the mitochondria were studied by transmission electron microscopy. The hearts of mice co-treated with A009 extracts along with cisplatin had reduced mitochondria damage compared to the ones treated with chemotherapy alone, indicating a cardioprotective role. To confirm the in vivo results, tumor cell lines and rat cardiomyocytes were treated with cisplatin in vitro with and without A009. Another frequently used chemotherapeutic agent 5-fluorouracil (5-FU), was also tested in this assay, observing a similar effect. A009 in vitro was additive to cisplatin and 5-FU to reduce cancer cell growth, while it did not further reduced growth of rat cardiomyocytes treated with cisplatin and 5-FU. A009 cardioprotective effects towards 5-FU chemotherapy were further investigated in vitro, using cardiomyocytes freshly isolated from mice pups. A009 mitigated toxicity of the fluoropyrimidine. Our study demonstrates that the polyphenol rich purified A009 extracts enhances the effect of chemotherapy in vitro and in vivo, but mitigates chemotherpy adverse effects on heart and on isolated cardiomyocytes. Olive mill waste water extracts could therefore represent a potential candidate for cardiovascular prevention in patients undergoing cancer chemotherapy.

AbstractThe commercial products humic acid (Actosol®), humic acid (Actosol®) + NPK and humic acid (Actosol®) + micro-elements (Fe, Mn, Cu) were tested against the root-knot nematode, Meloidogyne incognita, in vitro and in vivo on tomato and compared with the nematicide, Vydate. In vitro, Vydate at 2 ml l–1 water was the best treatment for inhibiting hatch (30.8% inhibition) and was significantly more effective than all other treatments, except Vydate at 4 ml l–1. Humic acid + micro-elements (2 ml l–1 water) was the least effective treatment for inhibiting hatch. Humic acid supplemented with micro-elements was significantly better than other products in reducing the number of surviving juveniles and achieving the highest percentage of nematode inhibition (49.2%), followed by the two concentrations of Vydate, which were not significantly different from one another. In vivo, all treatments significantly reduced the numbers of galls, embedded stages in roots, final population and population build-up (Pf/Pi) in all types of soil as compared to the untreated control. Materials appeared to be more effective at preventing nematode penetration of roots in sandy loam soil than in the other two soil types (sandy and clay). The double application of humic acid + NPK gave the best plant growth (fresh and dry weights) in sandy loam soil. All treatments reduced plant content of NPK in sandy soil except for humic acid + micro-elements and the two doses of Vydate.
