“…Aqueous, ethanol and chloroform extracts of leaves Carica papaya and Psidium guajava leaves also showed antifungal activity against Rhizopus species. One study by 44 suggested that the antimicrobial activity of Acalypha indica leaves extract could be attributed to the active compounds of alkaloids and tannins. According to a study conducted by 45 the presence of bioactive compounds such as alkaloids, tannins, steroids, saponins, flavonoids, glycosides, and phenolic compounds was also detected during it phytochemical testing.…”

Mucormycetes are a group of fungi causing a serious infection called mucormycosis. These fungi live throughout the environment, particularly in soil than in the air. This fungus is severely spread among people who have weakened immune systems; breathing in these spores can cause severe infection in the lungs or sinuses, which can spread easily to other parts of the body. In the present work, Rhizopus species was isolated from soil and antifungal activity of different solvent extracts of young leaves of Carica papaya (Papaya), Citrus limon (lemon), Psidium guajava (guava) and Acalypha indica (Indian nettle) were tested against Rhizopus species using the disc diffusion method. It was observed that all four plant leaves exhibit positive activity against Rhizopus species. Ethanolic extract of Carica papaya leaves (75mg/ml) showed more potency with an inhibition zone of 20 ± 0.2 mm. Aqueous extracts (25mg/ml) of Acalypha indica leaves (7±0.2 mm) showed lowest zone of inhibition found in against Rhizopus species. Antifungal activity of aqueous, ethanol, and chloroform extracts of Citrus limon leaves and Psidium guajava leaves also were determined. The results showed that more potential antifungal activity is exhibited with ethanol extract of Carica papaya leaves (75mg/ml). The present study confirmed the presence of antifungal compounds in shade-dried ethanol extracts of Carica papaya leaves against isolated Rhizopus species from the soil. INTRODUCTION:The amount and type of microorganisms in a particular section of soil are associated with several factors, such as sunlight, temperature, moisture, soil pH, nutrients, and reduction potential 1 . Various types of microorganisms are present in the soil. Among them, numerous groups of fungi are widely distributed in soil, and they play important roles in the soil environment some groups of fungi act as soil-borne pathogens.

“…The antipathogenic activity was likely from the effect of phenolic compounds in organic BPE. The phenolic compound inhibited microorganisms by degrading the lipid composition in cell membrane and inhibited the process of membrane biosynthesis causing disruption of cell membrane leading to the decrease in osmosis-barrier ability (Saryono et al, 2017).…”

This research aimed to optimize the extracting condition of banana peel (BP) and to investigate the effect of organic banana peel extract (BPE) on the immunity of giant freshwater prawn (Macrobrachium rosenbergii). The result demonstrated that the optimum extracting condition of organic BPE was 50% v/v of methanol at 100°C for 10 min. Under this condition, the maximum total phenolic content and extraction yield of 10.44 mg of gallic acid equivalents (GAE) per g of dry matter (mg GAE/g DM) and 33% w/v were obtained respectively. The organic BPE could inhibit an aquatic pathogen Aeromonas hydrophila at the minimum inhibitory concentration of 625 µg/disc. The main phytochemicals in organic BPE showed two major biological functions, which are antioxidant and antipathogenic activities. Subsequently, the effects of organic BPE on the immunity of M. rosenbergii were investigated. The results demonstrated that the organic BPE could increase immunity and phagocytic activity and decrease the susceptibility of M. rosenbergii. Moreover, the organic BPE could also increase total as well as differential haematocyte count, decrease the coagulation time and increase the total protein in serum of M. rosenbergii. The phagocytic activity of prawn was enhanced to 82.00% by using an organic BPE at 6 µg/g. At the same time, the cumulative mortality was declined to lower 20% after 6 days of organic BPE injection. In conclusion, organic BPE can be a potential immunostimulant in giant freshwater prawn culture. The utilization of BP in aquaculture can further add the value of BP and reduce organic pollutants.
