The present study was conducted to evaluate the in vitro antimicrobial activity of 2-Propanol extract of Parmotrema tinctorum (Despr. ex Nyl.) Hale, against each ten bacterial and fungal pathogens. Secondary compound of the species was extracted using Soxhlet apparatus and antimicrobial activity was carried out by using Bauer-Kirby disc diffusion method. The extract was found more effective against ten bacterial and eight fungal pathogens. The highest zones of inhibition in bacterial pathogens were noted against Escherichia coli (14.66 ± 0.57), Bacillus subtilis (13.0 ± 2.99), Salmonella abony (12.33 ± 2.51) and Corynebacterium rubrum (11.33 ± 0.57) followed by lowest inhibition zones were recorded in Streptococcus pyogenes (9.66 ± 0.57), Bacillus cereus (8.66 ± 1.15) and Streptomycin was taken as standard control found more effective against all the bacterial pathogens. In case of fungal pathogens the highest zones of inhibition were noted against Aspergillus flavus (10.0 ± 1.0) followed by Colletotrichum falcatum, Fusarium oxysporumand Penicillium chrysogenum (7.33 ± 0.57 each), Trichoderma lignorum (7.0 ± 1.53) and Fusarium moniliforme (6.0 ± 5.2) while commercially available synthetic antifungal drug Ketoconazole was taken as standard control found more effective against eight fungal pathogens. The study revealed that extracts obtained from P. tinctorum are having potential compounds which in turn useful to control human pathogenic microorganisms.

Cancer remains a major health issue worldwide due to the high rate of its morbidity and mortality. Search for tumor selective, novel anticancer compounds with lesser side-effects remains a major focus of cancer research. Endophytic fungi, owing to their chemical diversity, are an attractive source of bioactive metabolites. In the present study, we have explored the endophytic fungal population associated with a traditional Indian medicinal plant, Saraca asoca for their cytotoxic potentialities. Taxonomic identities and phylogenetic relationships of the fungal isolates were investigated using molecular techniques. 37 fungal species obtained from S. asoca were grouped into 22 genera of which the most dominant genus was Camarosporium followed by Pestalotiopsis and Fusarium. Fermentation extracts of all fungal isolates were assessed for their cytotoxic effects towards three human cancer cell lines, HeLa, HepG2 and PC3. 18 fungi exhibited remarkable cytotoxic activities among which Pestalotiopsis sp. 6 exhibited the most significant cytotoxicity towards all three cell lines used. Apoptosis inducing effect of Pestalotiopsis sp. 6 ethyl acetate culture extract (PS6) on HeLa cell line was further assessed by in vitro assays. PS6 induced mitochondria dependent apoptotic cell death in HeLa cells in a dose dependent manner. The study suggests these fungal extracts to be potential sources of secondary metabolites which can serve as promising lead molecules for the development of novel anti-cancer agents.

Ganoderma lucidum is a basidiomycetous white rot fungus which has been used for medicinal purposes for centuries particularly in countries such as China, Japan and Korea. Several classes of bioactive substances have been isolated and identified from basidiocarp, mycelia and spores of G. lucidum, such as polysaccharides, triterpenoids, nucleosides, sterols, fatty acids, protein and alkaloids. One of the major pharmacological properties of G.lucidum is antitumor activity and polysaccharides (GLPS) are the main component responsible for this property. In this paper, the possible role of host tree species in determining the composition of polysaccharides (GLPS) was examined. To date, a careful comparison of polysaccharides (GLPS) from different host tree species has not been performed. Fruiting bodies were collected from nine host tree species from different regions of India and examined for their polysaccharide composition. These fruit bodies were analyzed and compared on the basis of Gas liquid chromatography (GLC). The result showed the fruit body from Dalbergia sissoo was most potential for GLPS production, as it was composed of all six tested monosaccharides, including rhamnose, arabinose, xylose, fructose, glucose and mannose. It also showed the presence of intense host-dependent variability among isolates.

Pleurotus, commonly known as oyster mushroom, is a wood rotting mushroom that naturally grows on decaying logs. This mushroom has been cultivated using saw dust based substrate formulation. This study was undertaken to evaluate the growth performance of Pleurotus citrinopileatus, Pleurotus djamor and Pleurotus salmoneostramineus on coconut water gelatin and different physical factors such as pH, aeration, illumination and temperature conditions. Coconut water gelatin supported the mycelial growth of the three species as indicated by the luxuriant mycelial growth. Pleurotus citrinopileatus recorded fastest and shortest mycelial growth (90mm) after six days of incubation while Pleurotus salmoneostramineus showed slower mycelial growth (63.55mm), thick mycelial density and longest incubation period of eight days. Moreover, the three species grew best in pH 8.0, incubated either sealed or unsealed, both dark and lighted conditions at room temperature.

Fungi are essential part of the ecosystem because they play an important role in the decomposition of organic materials such as plant residues. Fungi feed on dead organic matter and return the nutrients back into the soil. However, the occurrence of fungi growing on leaf litters which are responsible for decomposition are not yet fully studied and documented. Thus, in this study the different species of fungi present in leaf litters of three species of forest trees namely, rain tree (Samanea), orchid tree (Clitorea) and paper tree (Gmelina) were isolated and identified. These fungal species could be potentially used to hasten the decomposition of enormous leaf litters of forest trees. The isolated fungal species were screened for their ability to produce cellulase. A total of 30 species of phyllosphere fungi were isolated namely: Absidia sp., Aspergillus flavus, A. fumigatus, A. japonicus, A. niger, A. niveus, A. tamarii, Colletotrichum gloeosporioides, Curvularia lunata, Eurotium repens, Fusarium acuminatum, F. semitectum, three unidentified species of Fusarium, Monascus ruber, Mucor piriformis, Neosartorya fischeri, Penicillium chrysogenum, P. citrinum, P. decumbens, P. hirsutum, P. implicatum, P. olsonii, P. oxalicum, P. purpurogenum, two unidentified species of Penicillium, Rhizopus microsporus and Trichoderma hamatum. Out of 30 species of phyllosphere fungi isolated, 22 can degrade cellulose as shown by the formation of clear zone around the colony of the organism. The five species of fungi that produced the largest clear zone were P. citrinum, P. olsonii, P. purpurogenum, A. niveus and P. chrysogenum.

Mycosphaerella musicola causes yellow sigatoka disease in banana plantations, and affects overall yield and quality of the fruit. Synthetic fungicides are used to control disease. An integrated approach by using plant based extracts and synthetic fungicides can control the disease efficiently by reducing the usage of fungicides. In vitro studies were carried out to test methanolic extracts of ten plants belonging to seven different families having previous reports on antimicrobial activity against Mycosphaerella musicola, methanolic extracts of two plants showed significant antifungal activity as well as significant inhibition of spore germination in spore germination inhibition assay. All eight fungicides exhibited inhibitory action on M. musicola in poison food technique, where as MIC range of each fungicide varied significantly. The results revealed that integrated disease management by using efficient plant extracts and effective fungicides can control the disease and the pathogen in fields efficiently.
