Contamination of feed with zearalenone (ZEA) is still a serious problem in farm animals feeding, especially in gilts, sensitive to this compound. The relative failure of current methods of decontamination and quality control lead us to look for new techniques. The commonly accepted method for breaking down ZEA was performed in controlled temperature and time conditions. Various sodium carbonate doses (0.5 – 4%) were added to feed naturally contaminated with ZEA (ZEA biosynthesis by F. graminearum isolates). These doses were found to be effective in in vitro studies. The addition of 2% sodium carbonate gave the best results in reducing the phytoestrogen in the feed.

To increase the profitability of the pulp and paper industry, additional value added products from lignocelluloses are needed, and consistent with this goal, a biorefinery concept based on the sodium carbonate pre-extraction of Trema orientalis prior to pulping was proposed. The solid content in the sodium carbonate pre-extracted liquor was much lower than the hot water pre-extraction, which affected the pre-hydrolysis yield and overall pulp yield positively. The alkaline pre-extraction had a beneficial effect on delignification in the subsequent soda-AQ-pulping. In addition, the alkaline pre-extraction improved the pulp bleachability. The papermaking properties of the alkaline pre-extracted soda-AQ pulp were very close to non-extracted pulp after D0EpD1 bleaching.

Agricultural wastes cause a serious environmental problem in Egypt. Utilization of these wastes by an environmentally friendly way is a very important issue. The objective of this study was to utilize rice straw into high-value products. Antioxidant activity, total soluble phenols, and flavonoids were evaluated in ethyl acetate extract prepared from rice straw after alkaline hydrolysis. Total phenols were found to be 221.6 mg gallic acid equivalents (GAE), while total flavonoids were 4.9 mg rutin equivalents (RE). The extract exhibited strong antioxidant activity measured by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method and its IC₅₀ value was 0.4 mg/ml. Furthermore, the ethyl acetate extract possessed high antioxidant activity assayed by β-carotene bleaching method and its value of lipid peroxidation inhibition (LPI) was 75.4%. It also exhibited high reducing power and its IC₅₀ value was equal to 0.06 mg/ml. HPLC analysis indicated that this extract contained seven phenolic acids including; protocatechuic, caffeic, syringic, p-coumaric, ferulic, rosmarinic and cinnamic, in addition to two flavonoids; qurecetin and kaempferol. Results indicated that ferulic and p-coumaric acids were the major soluble phenolic acids in rice straw, and their concentrations were 3.9 and 2.9 mg/g DW. It can be summarized that the strong antioxidant activity of ethyl acetate extract, prepared from rice straw, was highly correlated with its high level of phenolic compounds.

Określono wpływ kompostu jako dodatku organicznego poprawiającego właściwości podłoża oraz trzech rodzajów soli na wzrost siedmiu gatunków drzew i ośmiu gatunków krzewów ozdobnych, często wykorzystywanych w nasadzeniach przy drogach i ulicach. Rośliny podlewano roztworami NaCl, CaCl2 oraz Na2CO3, o przewodności elektrycznej 6,3 mS∙cm-1. Najwyższy wzrost poziomu EC podłoża zanotowano w mieszaninie torfu, kory i piasku, wyraźnie niższy poziom zasolenia miało podłoże z dodatkiem kompostu niezależnie od terminu pomiaru, po 8 czy po 12 tygodniach uprawy. Dodanie kompostu do podłoża poprawiło także wzrost robinii akacjowej, derenia białego ‘Sibirica’, bzu czarnego i tawuły van Houtta. Istotne znaczenie na wzrost testowanych drzew i krzewów miał jednak poziom zasolenia podłoża oraz rodzaj stosowanej soli. Tam, gdzie zasolenie miało wpływ na ograniczenie wzrostu roślin, chlorek sodu okazał się związkiem najsilniej hamującym przyrost dziesięciu gatunków roślin. Chlorek wapnia i węglan sodu ograniczały wzrost roślin w mniejszym stopniu. Jesion wyniosły, berberys Thunberga ʻAtropurpurea’ oraz bez czarny okazały się odporne na działanie wszystkich soli.
