Physical and Biological Behavior of Water Hyacinth Biomass for the Production of Cellulase Enzymes by Aspergillus niger and Trichoderma Reesei

Introduction

Water hyacinth, a rapidly growing aquatic plant, is often the primary cause of eutrophication in water bodies. This eutrophication occurs due to the plant's ability to drain the nutritional content and oxygen from the water, posing a significant threat to aquatic ecosystems. However, despite its negative impact, water hyacinth has a vast potential as a source of lignocellulose biomass for the production of cellulase enzymes by microbes such as Aspergillus niger and Trichoderma Reesei.

The Potential of Water Hyacinth as a Biomass Source

Water hyacinth is an ideal candidate for biomass production due to its high growth rate and abundance in aquatic ecosystems. The plant's biomass is composed of cellulose, hemicellulose, and lignin, which are the primary components of lignocellulose. Cellulase enzymes, produced by microbes such as Aspergillus niger and Trichoderma Reesei, play a crucial role in breaking down lignocellulose into simpler sugars, which can be used as a source of energy.

Preparation of Water Hyacinth Biomass

To increase the availability of cellulose for microbes, water hyacinth biomass requires preparation. This process involves physical and biological behavior. Physical behavior involves reducing the size of the water hyacinth biomass, while biological behavior involves the use of white rot fungi to degrade lignin, thereby increasing microbial accessibility to cellulose.

Physical Behavior

Physical behavior is a crucial step in preparing water hyacinth biomass for cellulase enzyme production. This process involves reducing the size of the biomass to increase the surface area available for microbial growth. The physical behavior of water hyacinth biomass can be achieved through various methods, including grinding, cutting, or crushing. The resulting biomass is then used as a substrate for microbial growth.

Biological Behavior

Biological behavior, on the other hand, involves the use of white rot fungi to degrade lignin. This process is also known as biodegradation, where the fungi break down the lignin component of the biomass, making it more accessible to microbes. The biological behavior of water hyacinth biomass can be achieved through various methods, including the use of fungi such as Phanerochaete chrysosporium.

Experimental Design

In this study, the variation of fermentation time was regulated in 3, 5, 7, 8, and 9 days, while the humidity level of the substrate was varied at 65%, 70%, 75%, 80%, and 85%. In addition, this research also explores the use of microbes in mono and mixed culture. The results showed that water hyacinth contains 27.78% cellulose, 37.50% hemicellulose, and 5.99% lignin. After preparation, lignin content decreases to 4.63% in physical behavior and 2.90% in biological behavior.

Analysis of Results

The best condition for the production of cellulase enzymes from the water hyacinth biomass after physical behavior occurs on the 7th day with a humidity level of 75%, using the culture of mono Aspergillus niger. In this condition, cellulase enzyme activity reaches 0.207 IU/ml. Meanwhile, for biological behavior, the best conditions are also achieved on the 7th day, but with 80% humidity level, which produces a cellulase enzyme activity of 0.107 IU/ml.

Conclusion

From this study, it can be concluded that water hyacinth has the potential as a source of biomass for the production of cellulase enzymes. Through physical and biological behavior, lignin content can be reduced, thereby increasing the availability of cellulose for microbes. With optimal fermentation conditions, the use of Aspergillus niger shows promising results. Further research is needed to explore the potential use of microbial culture mixtures and other pre-conquering methods that can increase the production of cellulase enzymes from water hyacinth.

Future Directions

The production of cellulase enzymes from water hyacinth biomass has significant potential for industrial applications. Further research is needed to explore the use of microbial culture mixtures and other pre-conquering methods that can increase the production of cellulase enzymes. Additionally, the development of more efficient methods for preparing water hyacinth biomass is also necessary to improve the yield of cellulase enzymes.
