2. Avocado oil as an inducer of the extracellular lipase activity of Kluyveromyces marxianus L-2029
Abstract Avocado represents one of the most nutritious and consumed foods in Mexico, and its export generates significant profits; because of its fatty acids content, the avocado oil was used as an inducer for the synthesis of extracellular lipases from the non-conventional yeast Kluyveromyces marxianus L-2029. Lipases are able to catalyze acyl glycerides, h

3. Epidemiological, clinical and immune factors that influence the persistence of antiphospholipid antibodies in leprosy
Abstract Introduction: Antiphospholipid antibodies (aPL) are described in individuals with leprosy without the clinical features of antiphospholipid antibody syndrome (APS), a condition involving thromboembolic phenomena. We have described the persistence of these antibodies for over 5 years in patients with leprosy after specific treatment. Objectives: To

4. Co-production of Proteases and Bioactive Protein Hydrolysates from Bioprocessing of Feather Meal
Abstract: Feather meal conversion through submerged cultivations with Bacillus strains (CL33A, CL14) yielded proteases and protein hydrolysates. After 4-day (CL33A) and 10-day (CL14) cultivations, protease activities reached 461 U/mL; hydrolysates presented antioxidant (radicals-scavenging, 57-77%; Fe2+-chelation, 14-28%; Fe3+-reduction) and antidiabetic (di

6. Lipase Production by Aspergillus niger C by Submerged Fermentation
Abstract This study aimed to evaluate the effects of variables on the process of lipases production by Aspergillus niger C by submerged fermentation (SmF). The production assays were performed in shake flasks for 72 hours at 150 rpm and 32°C. First, a fractional factorial design 25-1 (FFD) was carried out to evaluate the effect of the following process vari

7. ALKALINE PROTEASE PRODUCTION BY Bacillus licheniformis LBA 46 IN A BENCH REACTOR: EFFECT OF TEMPERATURE AND AGITATION
Abstract The production of protease from Bacillus licheniformis LBA 46 was studied in a 6 L reactor using the experimental design tool. The higher protease production was obtained in the exponential phase of growth reaching maximum activity (~3,000 U/mL) after 48 h of fermentation at 30 ºC and 300 rpm in a culture medium made of agroindustrial by-products.

9. Kinetic study of the effect of kiwi fruit actinidin on various proteins of chicken meat
Abstract In this research, the effect of kiwi protein on the physicochemical properties of chicken meat was investigated (Ross breed). Chicken thighs have been marinated in the form of cubes with dimensions of 2 cm in 20 mL of kiwi protein with activity of 0.9 u/mL for 2, 4, 6, 8, 24, 48, 72, and 96 hr, and kept in a refrigerator at 4 ± 1 °C. Then, the enz

10. Protective Effect of Vitamin C on Triptolide-induced Acute Hepatotoxicity in Mice through mitigation of oxidative stress
Abstract: Triptolide, a purified diterpenoid from the herb Tripterygium wilfordii Hook.f., was widely used to treat many diseases. However, the hepatotoxicity of triptolide limited its clinical use. Research showed oxidative stress played an important role in triptolide-induced liver injury. To investigate the effect of vitamin C, which was one of the most e
