In Every-days life we produces tons of waste, by utilizing Solid-State Fermentation Technology, we will convert wastes to valuable products; In SSF technology Wastes will be act as substrate.

1. FROM WASTE TO HIGH
VALUE ADDED PRODUCTS:
NOVEL ASPECTS OF SSF
IN THE PRODUCTION OF
ENZYMES
Presented By- Subhadeep Aditya

2. What Is SSF
• Solid state fermentation is a process occurs in the absence of
water, has been used for the production of various high value
added products such as enzymes and other organic
component.
• SSF is Responsible for production of lipase, protease, cellulase,
pectinase, insulinase etc
• In this solid state fermentation process the substates are the
waste materials, this wastes are basically nutrients for the
microorganisms, responsible for the fermentation.

3. Main Materials
• In SSF we basically use fungi
but depending upon the final
products various
microorganism are used.
• SSF used mainly waste
materials mainly from
agriculture & food industry,
such as wheat bran & peels
of fruits and vegetables

4. Advantage of SSF
Factors SSF
Substrate Wastes- non cost
Inoculum Not necessary
Aseptic condition Not needed
Contamination Less chance
Enzyme Yield Very high
Downstream process Easy, Cheap, not time consuming
Cost Very low

5. Type of waste materials used in SSF
process for production of Enzymes
Category of waste Type of waste Microorganism Enzymes
Waste of animal origin Fish flour
Chicken feather
Cow dung
Tannery solid waste
Aspergillus niger
Bacillus subtilis
Halomonas sp.
Synerggistes sp.
Protease
Wastes of Plant origin
And Food Industry
Wheat waste
Oil Waste
Rice Waste
Soy waste
Rhizopus oryzae
Apergillus sp.
Aspergillus niger
Aspergillus Spp.
Aspergillus funigatus
Bacillus pumilus
Aspergillus niger
Aspergillus oryzae
Lipase
Cellulase, Xylanase
Lipase, Amylase
Cellulase
Cellulase
Xylanase
Lipase
Celluase, Xylanase

6. Conclusion
• Recycle of these wastes, which are very cheap & highly
available in large amounts shows a high benefit of SSF from
Economic & Environmental perspective.
