Abstract

Background: Ecoenzymes, created from the fermentation of organic citrus waste, offer a sustainable method to produce Indole Acetic Acid (IAA), a phytohormone vital for plant growth. This study investigates the potential of these ecoenzymes in promoting sustainable agriculture. Objective: This study aims to evaluate the capacity of ecoenzymes derived from local citrus organic waste to synthesize IAA hormones. Methods: The ecoenzyme was extracted from fruit powders and centrifuged to separate the supernatant. One ml of ecoenzyme supernatant was then mixed with 2 ml of Salkowski reagent and incubated for 12 hours at room temperature in the dark to facilitate reaction. The presence and concentration of IAA were determined using spectrophotometry at a wavelength of 530 nm, while total protein levels were measured using the Warburg-Christian method. Results: ecoenzymes from local citrus sources contain IAA, with the highest concentration observed in sample 7A (30.26 µg/ml). The ecoenzyme exhibited favorable characteristics, including an average degree of acidity of 3.55, and the highest total protein content was found in sample 2A (144.277 mg/mL). Conclusion: Ecoenzymes from local orange peels successfully produce IAA, supported by fermentation-induced microbial activity and acidic conditions. This highlights their potential in sustainable agriculture.

Abstract

The majority of farmers currently use chemical fertilizers and pesticides in farming. However, continuous use of these materials can cause negative impacts such as environmental pollution, health risks, nutrient cycle imbalances, and reduced crop yields. To overcome this problem, research has been conducted that focuses on the use of microorganisms found in the soil layer surrounding plant roots, called the rhizosphere. These microorganisms such as bacteria, fungi and protozoa form a group known as Plant Growth Promoting Rhizobacteria (PGPR). PGPR can increase plant growth through various mechanisms such as nitrogen fixation, phosphorus dissolution, production of cyanide acid compounds (HCN), and Indole Acetic Acid (IAA) compounds. This research aims to collect and analyze articles related to the role of PGPR in sustainable agriculture. The method used is a literature review by collecting sources from Google Scholar and other internet databases. The results of the articles collected were on topics related to PGPR, including mechanisms of nitrogen fixation and phosphorus solubilization, as well as their role in producing IAA and siderophores. Apart from that, the research also discusses the role of PGPR as a biocontrol agent that can control plant pathogens, and the antagonistic activity of PGPR against pathogens.

Abstract

Fluorescent pseudomonas are a group of rhizobacteria that colonize plant root areas and have potential as biocontrol agents for plant diseases that can be developed. This group of bacteria can increase plant growth by producing growth hormones, one of which is producing hormones Indole Acetic Acid (IAA), solubilizing phosphate, and siderophores. Apart from that, fluorescent pseudomonas are also able to induce plant resistance by producing secondary metabolite compounds which have antimicrobial properties. Many studies have shown that one of the most abundant microorganisms in the rhizosphere (around the roots) is bacteria Pseudomonas spp. This review will discuss the occurrence, distribution, growth studies, mechanisms of action, and control of plant diseases by fluorescent pseudomonad bacteria. This literature review will be helpful for future research aimed at providing information that fluorescent pseudomonads have potential as biocontrol agents for plant diseases.

Abstract

The use of biological control agents as alternatives to synthetic fungicides is increasingly being developed as farmers become more aware of the negative effects of synthetic fungicides. Various biocontrol agents have been developed from several bacteria that are very effective against plant diseases, including pseudomonas fluorescent. The mechanism of bacterial inhibition against pathogens can take place through several ways, namely colonization, competition and antibiosis. Pseudomonas fluorescent is able to produce secondary metabolite compounds such as siderophores, HCN, antibiotics, enzymes that can inhibit the growth and development of pathogens and can induce systemic resistance.

Abstract

The repeated and unwise use of chemical fertilizers agricultural land can cause various negative impacts such as disrupting natural microbes and losing soil fertility. Phosphate solubilizing bacteria are soil bacteria that can convert phosphate from insoluble to soluble so that it can be absorbed by plants. Phosphate solubilizing bacteria play an important role in increasing plant productivity. Although the availability of phosphorus (P) in soil is in high concentrations, only 0.1% of the total phosphorus is available to plants and represents a small portion of the total in the soil. This occurs because of the low level of solubility of phosphorus and its fixation ability in the soil with several other metal elements in the soil such as Al, Ca, Fe to form aluminum phosphate, calcium phosphate and iron phosphate. There is no availability of phosphate for plants so that the role of phosphate-soluble bacteria is needed which plays a role in providing phosphate for plants so that it can increase agricultural yields. Phosphate solubilizing bacteria have great potential as biofertilizers because they can increase the bioavailability of phosphorus for plants, promote sustainable agriculture, and increase soil fertility, and increase crop yields.
