Isolation And Test Of The Potential Of Cellulololytic Microorganisms In The Decomposition Of The Remaining Deli Tobacco Plants Of PTPN II Kebun Sampali
Introduction
The utilization of remaining Deli tobacco plants as organic fertilizer is a promising solution to increase soil fertility and reduce environmental impacts. The process of decomposing the remaining plants involves the important role of cellulolytic microorganisms, which are able to break down cellulose into simple sugar that can be absorbed by plants. This study was conducted at the Laboratory of Soil Biology and Central Laboratory, Faculty of Agriculture, University of North Sumatra, Medan, with a focus on isolating and testing the potential of cellulololytic microorganisms from the remaining Deli tobacco plants.
Materials and Methods
This study uses a complete non-factorial random design with two treatments and two replications. The treatment includes microorganism isolates obtained from the remaining Deli tobacco plants, namely:
- Mushroom isolates: TJ8 and TJ12
- Bacterial isolate: TB4 and TB10
- Aktinomisetetes isolates: TA2 and TA5 In addition, controls (TO) and microorganisms from laboratories (LJ, LB, LA) are also used, as well as the combined treatment of fungal isolates, bacteria, and actinomisetes (TJTBTA).
Results
The results showed that mushroom isolates 12 had the highest ability to produce reduction sugar, followed by mushroom isolates 8. This indicates that mushroom isolates 12 and 8 have great potential as cellulose decomposers in the residual Deli tobacco plants.
Furthermore, mushroom isolates 12 also recorded the highest decline in the C/N ratio (10.02), followed by mushroom isolates 8 (10.04). A decline in the value of the C/N ratio shows an increase in the quality of organic fertilizer, because the lower the C/N ratio, the faster the decomposition process and the easier the plants absorb nutrients.
Discussion
This study provides valuable information about the potential of cellulololytic microorganisms from the rest of the Deli tobacco plant in supporting the decomposition process and producing quality organic fertilizer. These results can be applied in efforts to manage sustainable Deli tobacco waste, as well as open opportunities to develop biofertilizer technology from local resources.
Conclusion
The findings of this study highlight the importance of cellulololytic microorganisms in the decomposition of Deli tobacco plants. The results suggest that mushroom isolates 12 and 8 have great potential as cellulose decomposers, and their use can lead to the production of high-quality organic fertilizer.
Recommendations for Future Research
Further development can be done by testing the effectiveness of mushroom isolates 12 and 8 in increasing the growth of Deli tobacco plants. In addition, optimization of composting conditions with the addition of isolated cellulolytic microorganisms can be studied to improve the efficiency of decomposition and produce high-quality organic fertilizer.
Implications for Sustainable Waste Management
The results of this study have significant implications for sustainable waste management. The use of cellulololytic microorganisms can help to reduce the environmental impacts of Deli tobacco waste, and promote the production of high-quality organic fertilizer. This can contribute to the development of sustainable agricultural practices, and support the achievement of environmental sustainability goals.
Limitations of the Study
This study has some limitations that should be noted. The study was conducted in a laboratory setting, and the results may not be directly applicable to field conditions. Additionally, the study only examined the potential of cellulololytic microorganisms from the remaining Deli tobacco plants, and did not investigate the potential of other microorganisms.
Future Directions for Research
Future research should focus on testing the effectiveness of mushroom isolates 12 and 8 in increasing the growth of Deli tobacco plants, and optimizing composting conditions with the addition of isolated cellulolytic microorganisms. Additionally, the study of other microorganisms that can contribute to the decomposition of Deli tobacco plants should be conducted.
Conclusion
In conclusion, this study provides valuable information about the potential of cellulololytic microorganisms from the rest of the Deli tobacco plant in supporting the decomposition process and producing quality organic fertilizer. The results of this study have significant implications for sustainable waste management, and highlight the importance of cellulololytic microorganisms in the decomposition of Deli tobacco plants.
Q: What are cellulololytic microorganisms?
A: Cellulololytic microorganisms are microorganisms that are able to break down cellulose, a complex carbohydrate found in plant cell walls. These microorganisms play an important role in the decomposition of plant material, including Deli tobacco plants.
Q: Why are cellulololytic microorganisms important for Deli tobacco plant decomposition?
A: Cellulololytic microorganisms are important for Deli tobacco plant decomposition because they are able to break down the cellulose in the plant material, releasing simple sugars that can be absorbed by plants.
