New Technologies in Agriculture Sector
High Agar Yield and Gel Strength
Agar production in global industrial scale has increased 9600 tons (US$ 173 million) in 2009 to 14,500 tons (US$ 246 million) in 2015. • Hence, the needs for transcript and protein markers and marker technology will logically increase according to the market size of agar industry. • Seaweed providers: Malaysia, Indonesia, Philippines, China, Chile, Peru, Brazil, Mexico, South Africa etc. • Seaweed manufacturers: Japan, China, United States of America etc.
Agar derived from the cell wall matrix of red seaweeds is the most expensive hydrocolloid which has wide applications in biological research, and in food, cosmetics and pharmaceutical domains. • The yield and quality of agar determine its commercial and industrial value in phycocolloid market with gel strength as the main indicator for agar quality. • Selection of commercially potential seaweed samples and evaluation of agar properties with conventional method are ineffective in terms of time and cost, labour intensive and requires a large quantity of raw materials.
These inventions involve measurement of transcript abundance of transcript markers with quantitative reversetranscription (qRT)-PCR using specific primers, and protein accumulation of protein markers by Western blot using specific antibodies. • The use of molecular markers (transcripts and proteins) that are associated with agar yield and gel strength could offer a rapid and accurate screening tool needed for quick estimation of agar yield and gel strength in seaweed samples.
