One of the waste products of the industrial process of the sugar and alcohol agribusiness is filter cake (FC). This waste product has high levels of organic matter, mainly proteins and lipids, and is rich in calcium, nitrogen, potassium and phosphorous. In this work we characterized samples of FC from sugar and alcohol industries located in sugarcane-producing regions in Brazil and assessed the adsorption of potentially toxic metals (Cu(II), Cd(II), Pb(II), Ni(II) and Cr(III)) by this waste in mono- and multi-elemental systems, seeking to use FC as an adsorbent in contaminated environments. The characterization of FCs showed significant differences between the samples and the adsorption studies showed retention of over 90% of potentially toxic metals. In a competitive environment (multi-metallic solution), the FC was effective in adsorbing all metals except lead, but less effective compared to the mono-metallic solution. These results show the potential for use of this residue as an adsorbent in contaminated environments.

Objective: To evaluate the effects of a combination of carnitines, L-arginine, L-cysteine and myo-inositol on metabolic and reproductive parameters in PCOS overweight/obese patients.
Methods: This was a retrospective study analyzing information of a group of PCOS ( = 25) overweight/obesity patients, not requiring hormonal treatment, selected from the database of the ambulatory clinic of the Gynecological Endocrinology Center at the University of Modena and Reggio Emilia, Modena, Italy. The hormonal profile, routine exams and insulin and C-peptide response to oral glucose tolerance test (OGTT) were evaluated before and after 12 weeks of a daily oral complementary treatment with L-carnitine (500 mg), acetyl-L-carnitine (250 mg), L-arginine (500 mg), L-cysteine (100 mg) and myo-inositol (1 gr).

The cytoplasmic membrane of bacteria is composed of a phospholipid bilayer made up of a diverse set of lipids. Phosphatidylglycerol (PG) is one of the principal constituents and its production is essential for growth in many bacteria. All the enzymes required for PG biogenesis in have been identified and characterized decades ago.

The enzyme D-sorbitol dehydrogenase (SLDH) facilitates the conversion of D-sorbitol to L-sorbose. While current knowledge of this enzyme class predominantly centers on Gluconobacter oxydans, the catalytic properties of enzymes from alternative sources, particularly their substrate specificity and coenzyme dependency, remain ambiguous. In this investigation, we conducted BLASTp analysis and screened out a novel SLDH (Fpsldh) from Faunimonas pinastri A52C2.

Present research focused on biotransformation of paneer whey into a functional fermented product using kefir culture. Out of 9 formulations (S-1 to S-9) tried; S-8, obtained by fermenting FOS (1%) supplemented paneer whey and adding 8% refined sugar, was identified as the most acceptable product. Nutritional analysis revealed the following as per 100 g of product: 44.

Hypoxia poses a serious challenge for all animals; however, certain animals exhibit a remarkable resilience in the case of prolonged and severe hypoxia. The Siberian wood frog is a unique amphibian capable of surviving for up to several months at almost complete anoxia. We investigated changes in the metabolome of at the onset of hypoxia (day 1) and within 1 h of reoxygenation after a long-term hypoxia using H NMR.
