“…Most of the strains were found to be pigment producers however special interest toward a red color directed further study on Penicillium, which was then interogatted for optimization of its media conditions and the effect of metals and salts on pigment yield. The main purpose of the study was to optimize the effect of various bioelements (Chintapenta et al, 2014) and it was shown that a higher concentration of salt has a negative effect on pigment yield. This is due to the fact that the presence of these electrolytes alter the pH of the medium and prevent diffusion of pigment.…”

IntroductIonMicroorganisms have caused epidemic, endemic diseases, and deaths of hundreds of millions of humans as well as animal morbidity and mortality worldwide. Microorganisms have developed sophisticated defense mechanisms for their survival in the host cells and to overcome the host defense system such as cells of the immune system, lysozyme attack, cytokinines, complements, antibodies, and phagocytosis. [1] Bacterial infection process attachment and penetration to epithelial cells, multiplication, synthesis of toxins and enzymes, and finally damages the whole cell. [2] The Staphylococcus aureus is a most pathogenic organism of the genus Staphylococcus, and it causes community-acquired and nosocomial infections worldwide. [3] The S. aureus is found in the digestive tracts, livestock, human skin and causes ophthalmic infections with skin infections and sepsis. [4] It is reported that S. aureus causes more fatalities in the USA than AIDS because of antibiotic resistance. [5] The skin and soft-tissue infections are caused by methicillin-resistant S. aureus (MRSA) strain known as USA300. [6] The presence of MRSA has also been established in cats, horses, and rabbits by researchers. [7] Bacillus subtilis damages mammalian membrane by producing lecithinase enzyme. In humans, B. subtilis causes allergic reactions and food poisoning by the production of extracellular toxins. [8] This bacterium causes endocarditis in infants, bacteremia in the patients with the impaired immune system. [9] In hospitals, causes wound infection in hospitalized patients due to the spores production. [9] B. subtilis also contaminates laboratory media. [8] The Salmonella species are Gram-negative bacteria that cause typhoid fever and enterocolitis, intestinal or diarrheal disease Background: Chaetomium cupreum is soil-isolated pigment-producing fungus used as biocontrol agent. Hypothesis: The aim of the present study was to evaluate the bioactive constituents and antibacterial potential of C. cupreum extracts on bacteria such as Staphylococcus aureus, Bacillus subtilis, Salmonella typhi, and Proteus vulgaris. Materials and Methods: The qualitative and quantitative screening of secondary metabolites was done by standard procedures. The antibacterial activity of different extracts of C. cupreum was determined by agar well diffusion method and broth microdilution methods. Results: Among the different extracts of C. cupreum, ethyl acetate and n-butanol extracts exhibited antibacterial activity. In the n-butanol extract, the most susceptible organism was found to be B. subtilis with zone of inhibition 18.5 ± 0.7 mm, followed by P. vulgaris 15.5 ± 0.7 mm, S. typhi 12.5 ± 3.5 mm, and S. aureus 12.0 ± 2.8 mm at 0.5 mg/ml, whereas in the ethyl acetate extract, the most susceptible organism was to found be P. vulgaris with zone of inhibition 17.5 ± 0.7 mm followed by B. subtilis 17.0 ± 1.4 mm, S. typhi 14.0 ± 0.7 mm, and S. aureus 13.5 ± 0.7 mm at 0.5 mg/ml. Conclusion: The obtained results suggest that C. cupreum extracts contain compounds that po...

“…1 filter paper and the broth containing the extracellular metabolites was obtained. The extraction of pigments was carried out according to the method described by Lathadevi et al [19]. The broth obtained was used for the extraction of the different compounds by separating funnel using different organic solvents from non-polar to polar (chloroform, ethyl acetate, n-butanol, and methanol) in the ratio of 1:1.…”

Objective: This study evaluated the Chaetomium cupreum extracts as biocontrol agents against four plant pathogenic fungi (Cladosporium cladosporioides, Fusarium oxysporum, Phomopsis azadirachtae, and Rhizoctonia solani).Method: The antifungal activity of n-butanol and ethyl acetate extracts of C. cupreum was evaluated against plant pathogenic fungi using food poison method.Result: In n-butanol extract, the percentage inhibition of mycelial growth against C. cladosporoides was 88.3±0.1, F. oxysporum was 59.4±0.2, R. solani was 56.2±0.9, and P. azadirachtae was 52.0±0.1at 0.25 mg/ml, respectively. In ethyl acetate extract, the percentage inhibition of mycelial growth against C. cladosporoides was 86.0±0.5, F. oxysporum was 66.4±0.1, P. azadirachtae was 55.2±0.9, and R. solani was 52.0±0.1 at 0.25 mg/ml, respectively.Conclusion: It was found that n-butanol extract is more effective than ethyl acetate extract of C. cupreum. Future studies will focus on the purification and characterization of compounds of C. cupreum and their biocontrol capacity with the mechanism for plant pathological applications.
