In order to develop new antimicrobial agents, a series of 3-formyl indole based Schiff bases were synthesized by reacting 3-formyl indole(indole-3-carboxaldehyde) with substituted aniline taking ethanol as solvent. The reaction was carried in the presence of small amount of p-toluene sulphonic acid as catalyst.All the synthesized compounds were characterized by IR, 1H-NMR spectral analysis. All the synthesized compounds were evaluated for antimicrobial activity against two gram positive bacterial strains (B. subtilisand S. aureus) and two gram negative bacterial strains (P. aeruginosaand E. coli) and one fungal strain (C. albicans). All the synthesized compounds were found to have moderate to good antimicrobial activity. The  standard drug amoxicillin, fluconazole were used for antimicrobial activity. Among the synthesized compounds, the maximum antimicrobial activity was shown by compounds GS04, GS07, GS08 and GS10.

Four new polyketides have been identified in culture filtrates of the fungal strain Penicillium sp. IBWF104-06 isolated from a soil sample. They are structurally based on the same trans-decalinpentanoic acid skeleton as tanzawaic acids A–H. One of the new compounds was found to inhibit the conidial germination in the rice blast fungus Magnaporthe oryzae at concentrations of 25 μg/mL.

Enhancement in the production of enzyme by utilizing different strains of microbe is one of the main prospects in biotechnology. In the present work, ethyl methane sulfonate (EMF) was selected as the chemical mutagen for inducing mutagenesis in fungi. It is a cheap method to induce random mutation as compared to other methods of recombinant technologies. Strain improvement was done by incubating the fungal spore suspension at variable concentrations of EMS i.e. 4% (v/v) and 10% (v/v) for the time period of 60, 90, and 120 min respectively. The set of control was treated with distilled water only. The fungal colonies were found to be maximum in control plate as compared to the EMF exposed plates. The number of fungal colonies was reduced as we raised the exposure time of EMF. Specific activity and the lipase activity of wild strain and hyperproducer were evaluated under the submerged (SmF) and solid-state fermentation (SSF). The wild strain denoted the 3.2 U/ml/min of enzymatic activity under SmF and 15.87 U/g/min of activity under SSF. In contrast, the best enzymatic activity was represented by S2St1 at 10% of EMS after the time period of 60 min i.e. 11.7 U/ml/min under SmF and 99.35 U/g/min under SSF after the time period of 72 hrs. Statistical analysis by using one-way ANOVA determined that the value of F calculated was lower than the F tabulated. So, there was a significant relation between the EMS percentage and time of exposure among the mutated strains. In conclusion, this soil fungal strain can be utilized to produce lipase enzyme for numerous industrial applications.

Abstract Spilanthol is a bioactive alkylamide from the native Amazon plant species, Acmella oleracea. However, antifungal activities of spilanthol and its application to the therapeutic treatment of candidiasis remains to be explored. This study sought to evaluate the in vitro and in vivo antifungal activity of spilanthol previously isolated from A. oleracea (spilanthol(AcO)) against Candida albicans ATCC® 10231™, a multidrug-resistant fungal strain. Microdilution methods were used to determine inhibitory and fungicidal concentrations of spilanthol(AcO). In planktonic cultures, the fungal growth kinetics, yeast cell metabolic activity, cell membrane permeability and cell wall integrity were investigated. The effect of spilanthol(AcO) on the proliferation and adhesion of fungal biofilms was evaluated by whole slide imaging and scanning electron microscopy. The biochemical composition of the biofilm matrix was also analyzed. In parallel, spilanthol(AcO) was tested in vivo in an experimental vulvovaginal candidiasis model. Our in vitro analyses in C. albicans planktonic cultures detected a significant inhibitory effect of spilanthol(AcO), which affects both yeast cell membrane and cell wall integrity, interfering with the fungus growth. C. albicans biofilm proliferation and adhesion, as well as, carbohydrates and DNA in biofilm matrix were reduced after spilanthol(AcO) treatment. Moreover, infected rats treated with spilanthol(AcO) showed consistent reduction of both fungal burden and inflammatory processes compared to the untreated animals. Altogether, our findings demonstrated that spilanthol(AcO) is an bioactive compound against planktonic and biofilm forms of a multidrug resistant C. albicans strain. Furthermore, spilanthol(AcO) can be potentially considered for therapeutical treatment of vulvovaginal candidiasis caused by C. albicans.
