The parks of Mumbai are frequently visited by local residents every morning and evening. However, there are no reports on the occurrence of keratinophilic fungi in these areas. The purpose of this research was to study the occurrence of keratinophilic fungi in the public parks of Mumbai. One hundred soil samples were collected from five public parks: Kamla Nehru Park, Powai Garden, CD Deshmukh Garden, Five Gardens and Chota Kashmir. Keratinophilic fungi were isolated by the hair baiting technique using human hair as keratin bait. The cultures were identified using macroand micro-morphological features. Identification was also confirmed by the BLAST search of sequences of the ITS1-5.8S-ITS2 rDNA region against the NCBI/Genbank data and compared with deposited sequences. The ability of these fungi to use human hair was also evaluated by release of protein in liquid media. A total of 75 strains of keratinophilic fungi were recovered from 100 (75.0%) soil samples. The isolated fungi were composed of eleven species of eight genera: <em>Arthrographis kalrae</em>, A<em>uxarthron conjugatum</em>, <em>Chrysosporium indicum</em>, <em>C. queenslandicum</em>, <em>C. zonatum, Gymnascella dankaliensis</em>, <em>G. hyalinospora</em>,<em> Microsporum gypseum</em> (15.0%), <em>Myriodontium keratinophilum</em>, <em>Trichophyton mentagrophytes</em> and <em>Uncinocarpus reesii</em>. These fungi can release 148.8-307.6 μg/mL protein in liquid media when grown on human hair in shake flask culture and also decompose 16.2-38.6% of human hair after four weeks of incubation. Our study indicates that keratinophilic fungi are to be found in the soils of various public parks in Mumbai and that human hair can be a source of pathogenic fungi.

Biosurfactants are surface-active compounds that have sparked interest in recent years because of their environmental advantages over conventional surfactants. The aim of this study was to investigate the production of biosurfactants by soil fungi isolated from the Amazon forest. Fungi colonies were isolated from soil samples and screened for biosurfactant production in submerged fermentation. In addition, the influences of bioprocess factors (carbon source, nitrogen source, pH, and fermentation time) were investigated. Finally, the biosurfactant produced was semipurified and submitted to stability tests. One hundred fungal cultures were obtained from the soil samples, identified by micromorphology, and submitted to screening for biosurfactant production. Sixty-one strains produced biosurfactants. The strainPenicillium8CC2 showed the highest emulsification index (54.2%). The optimized bioprocess conditions for biosurfactant production byPenicillium8CC2 were as follows: soybean oil, 20 g/L; yeast extract, 30 g/L; pH 9; duration of 9 days. The semipurified biosurfactant showed stability after heating at 100°C for 60 min and after the addition of 30% NaCl (w/v). Tween 80 (0.2% w/v), a conventional surfactant, was used as the control.

The fungus Gliocladium sp. is the microbial soil that can be isolated from the root zone of banana plant  (Musa Paradica L.) Those fungi are included in the group of potentially antagonistic microbes in the growth inhibiting of Fusarium sp fungus which infects the plants and it cause disease on banana crops withered. This research aim was to know the difference of growth inhibiting percentage of Gliocladium sp, to the Fusarium sp. fungus at pH 5.5 and pH 7. This research uses experiment methods. The results of the growth inhibiting percentage in the last day was higher at pH 5.5 of 35.2% whereas at pH 7 of 14%. This indicates that the growth of the fungus is more suitable in pH acidic approach because of its nature which is able to adjust to the fungal metabolism. The inhibition mechanism of the Gliocladium sp. on fungus inhibiting of Fusarium sp. has the stages of the competition, lysis and mycoparasit.

ABSTRACT We studied the feeding behavior and the activity period of three phyllostomid bat species on Musa paradisiaca inflorescences in an orchard located in southeastern Brazil. Glossophaga soricina (Pallas, 1766), Anoura caudifer (É. Geoffroy, 1818), and Phyllostomus discolor (Wagner, 1843) were frequently observed, videotaped, and mist-netted visiting banana inflorescences. Three approaching strategies on banana inflorescences were performed by bats: hovering (glossophagine species), upside landing (G. soricina), and downside landing (P. discolor). A new feeding behavior that consisted in hovering and licking the nectar that dripped from the distal part of a closed bract was observed for glossophagines. Visits occurred throughout the night (from 18:00 h to 05:00 h). However, activity pattern of nectarivorous bat species was significantly different from the omnivorous bat species, with the formers presenting visiting peaks at 21:00 hs and 23:30 hs, and the second at 23:45 hs and 02:30 hs. Dietary specialization, body size, and foraging behavior are important features that are linked to kind of approaching strategies to flowers and activity period of bats. Although bat visits on M. paradisiaca inflorescences are not reproductively important to banana plant, its nectar is a frequent and abundant food source for bats from the family Phyllostomidae, at least in Southeastern Brazil.

The use of banana plant sap as an incision remedy has been carried out through generations in Citatah Village, Cipatat District, West Bandung Regency, Indonesia. This study aimed to examine the ethnobotanical utilization of banana plant sap as an incision remedy. The research was conducted using the snowball sampling technique by the method of structured observation and interviews with 30 respondents. The followings were tools and materials used for the research, a set of stationery, cameras, voice recorders, and laptops. The data obtained were analyzed using qualitative and quantitative descriptive analysis. The results showed that of the thirty respondents who knew the utilization of banana plant sap as wound remedy, only 60% were still using it. Parts of banana plants that were often used by the community was the banana plant shoots by 87% of the total respondents and banana leaf fronds by 13%. There was no specific type of banana used for this wound remedy. However, the type of banana most widely used by the community was ambon Banana (Musa paradisiaca var. sapientum) with a percentage of 20%, kulutuk/manggala banana (Musa balbisiana) 60%, and kepok Banana (Musa paradisiaca formatypica) 20%. Based on the results of the observation and interview, there were at least four benefits of using banana sap, namely preventing infection, sticking wounds, stopping bleeding, and drying the wound. While scientifically, this banana sap can be used as the wound remedy because it contains flavonoid compounds, saponins, triterpenoids, steroids, alkaloids, ascorbic acid, and tannins.
