Antioxidants are compounds that can prevent or slow cellular damage caused by unstable molecules called free radicals. This document discusses various antioxidants found in foods, including carotenoids, flavonoids, phenols, and vitamins. It provides details on the antioxidant content and sources of different foods, and how food processing methods like heating, peeling, and canning can impact the antioxidant levels. Cooking methods like blanching and thermal processing are found to influence carotenoid levels through isomerization, degradation, and cell wall breakdown.

Production of Pectinase by Aspergillus niger Cultured in Solid State Media - IJBInnspub Net
Solid state fermentation was carried out with 7 fungal strains, obtained from different sources. Among 7 isolates Aspergillus niger,IM-6 was found as effective pectinase producer.Maximum enzymatic activity (142.44U/gm) was observed after 7 days incubation at 40˚C temperature in 750 ml conical flask. In this study 1.69% (NH4)2SO4 was used as nitrogen source, although peptone as a nitrogen source showed better result but use of peptone was not cost effective. As a substrate, wheat bran and potato starch showed good result (85.54U/gm) in solid state culture. Addition of 9.68% pectin was found to increase the enzyme production as 116.57U/gm. Pectinase production was optimum in 60% moisture (98.34U/gm). Aeration showed positive effects on pectinase production (136.86U/gm) at 750 ml flask than 1000 ml flask. Thus the wild strain Aspergillus niger IM-6 has outstanding pectinase producing capability at 40◦C in 60% initial moisture content for 7 days of incubation in solid state fermentation.

Writing your CV & preparing for interview - Information for tax professionalsThe SR Group
The objective of your CV is to gain you an interview either with a potential employer or a recruitment consultant, and to create a positive impression about you in the mind of the
interviewer before you meet.
It is a good idea to split your CV into four sections: personal information, qualifications, employment history and interests.
Organisations interview in many different ways both in terms of style as well as process. As an interviewee you should never assume that each interview will be structured in exactly the same way and you should always aim to improve your interview style through better preparation and understanding of the interview process. Of course, your greatest ally is the recruitment consultant you are working with who will be able to prepare you based on their knowledge of the organisation and role in question.

Optimization and Production of Itaconic Acid from Estuarine Aspergillus terre...BRNSS Publication Hub
Itaconic acid (IA) is an organic acid. It is used in medicine, resins, agriculture, and polymer production. In the present study, sediment sample was collected aseptically from Vellar estuary, Parangipettai, Tamil Nadu, India. About 1.6 × 102 to 6.1 × 103 colony forming units/g density of fungal strains were isolated and screened for IA production. As a result of the tested strains Aspergillus terreus was observed as the most potential strain. Optimization was done at different temperatures (25–45°C), in different pH (5.0–7.0). The impact of salinity on IA production was evaluated using various salinity (5–25 ppt), carbon sources (1% w/v of glucose, sucrose, dextrose, and maltose), nitrogen sources (0.5% sodium nitrate, ammonium nitrate, and potassium nitrate), and cheaper sources (1% w/v molasses, jackfruit waste, wheat bran, and coconut oil cake). As a result optimized culture condition for IA production was 1% w/v of glucose - best carbon source, 1% w/v molasses - best cheaper carbon source, 0.5% of sodium nitrate - best nitrogen source, salinity - 20 ppt, temperature - 40°C, and pH - 5.5 and incubation time – 96 h. Compared to glucose (0.41 mg/ml) production of IA was high when molasses (0.61 mg/ml) was used as carbon source, it is also economically good. Mass scale culture was done using molasses instead of glucose with an optimized parameter. After mass scale culture, IA production was 6.3g/l.
