Keratinophilic Fungi from the vicinity of salt pan soils of Sambhar lake Rajasthan (India).
Journal de mycologie medicale, 2018Co-Authors: Sunil Kumar Deshmukh, Shilpa Amit Verekar, Y.g. ChavanAbstract:Forty soil samples were collected from seven sites in the vicinity of Sambhar lake Rajasthan, India and screened for the presence of Keratinophilic Fungi using hair baiting techniques for isolation. Seventeen isolates were recovered and identified. The cultures were identified by recognition of their macro- and micro- morphological features. Their identification was confirmed by BLAST using ITS1-5.8S-ITS2 rDNA region and sequences have been deposited in NCBI data base. A total of 34 species belonging to 29 genera were isolated. Among the dermatophytes and related Keratinophilic Fungi Chrysosporium indicum was predominant followed by Ctenomyces serratus, C. tropicum, Keratinophyton durus, Auxarthron conjugatum, Gymnascella dankaliensis, Gymnoascoideus petalosporus and Uncinocarpus reesii. Twenty-six species belonging to 22 genera represented other species. Our study indicates that Keratinophilic Fungi and species are found in the soils at the vicinity of the Sambhar Lake, and human activities can be the potential source of pathogenic Fungi.

Prevalence of Keratinophilic Fungi in public park soils of Mumbai, India
Microbiological Research, 2012Co-Authors: Sunil Kumar Deshmukh, Shilpa Amit VerekarAbstract: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: Arthrographis kalrae , A uxarthron conjugatum , Chrysosporium indicum , C. queenslandicum , C. zonatum, Gymnascella dankaliensis , G. hyalinospora , Microsporum gypseum (15.0%), Myriodontium keratinophilum , Trichophyton mentagrophytes and Uncinocarpus reesii . 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.

Prevalence of Keratinophilic Fungi in usar soils of Uttar Pradesh, India
Microbiological Research, 2011Co-Authors: Sunil Kumar Deshmukh, Shilpa Amit VerekarAbstract:Alkaline soils commonly called as Usar soil having pH 7.5 to 11.0 is commonly found in regions having poor drainage and little percolation. These soils occupy vast tracts of barren lands in the northern parts of India. These areas are frequently visited by man and animals, however there are no reports on the occurrence of Keratinophilic Fungi from the Usar soils. The purpose of this research was to study the occurrence of Keratinophilic Fungi in the alkaline Usar soil. To investigate the occurrence of soil Keratinophilic Fungi from Usar soil, 120 samples were collected from five districts of Uttar Pradesh viz. Lucknow, Bareilly, Azamgarh, Balia and Pratapgarh. Keratinophilic Fungi were isolated by the hair baiting techniques using human hair as keratin bait. The cultures were identified using macro- and micro morphological features. Eighty-tow strains of Keratinophilic Fungi were recovered from 120 (68.33%) soil samples. The isolated Fungi were composed of ten species of five genera viz. Chrysosporium indicum (19.16%), Microsporum gypseum (12.5%), Chrysosporium tropicum (10.0%), Chrysosporium pannicola (7.5%), Trichophyton terrestre (5.83%), Chrysosporium lucknowense (4.16%), Chrysosporium state of Ctenomyces serratus (3.33%), Gymnascella dankailensis (3.33%), Gymnoascus reessii (1.66 %) and Trichophyton mentagrophytes (1.66 %). The presence of Keratinophilic Fungi in the Usar soils of Uttar Pradesh, India indicates that these Fungi do occur at higher alkalinity.

Sewage sludge particle size fractions affect keratinolytic and Keratinophilic Fungi
2006Co-Authors: K. Ulfig, Grażyna Płaza, M. TerakowskiAbstract:Previous studies indicated that particle size distribution affects the composition of keratinolytic and Keratinophilic Fungi in sewage sludge. The present study was to determine the composition of these Fungi in sludge particle size fractions (> 1, 1–0.5, 0.5–0.25, 0.25–0.125, 0.125–0.063, 0.063–0.032 and < 0.032 mm) in a model experiment. In the original sludge sample and its fractions, the composition of keratinolytic and Keratinophilic Fungi was determined by using the hair baiting method. The composition of actidione-resistant Fungi was also determined by using the dilution method and the Wiegand medium supplemented with chloramphenicol (100 mg/dm) and actidione (500 mg/dm). The number of keratinolytic and Keratinophilic Fungi isolated by the hair baiting method was lower in fractions than in the original sludge sample. In contrast, fungal quantities obtained by the dilution method were higher in fractions than in the original sludge sample. Qualitative differences were also observed. The conclusion was that nutrient factors associated with sludge particle size fractions, chiefly total sulfur content and C:S ratio, affected the composition of keratinolytic and Keratinophilic Fungi in the sludge more than the fungal propagule quantities (inocula).

Sludge Liming Decreases the Growth of Keratinolytic and Keratinophilic Fungi
Polish Journal of Environmental Studies, 2006Co-Authors: K. UlfigAbstract:Due to the content of pathogenic organisms, including Fungi, sewage sludge land application poses risks to both human health and the environment. One of the ways for reducing pathogens in sludge is liming. This study aims to determine the effect of sludge liming on the composition of keratinolytic and Keratinophilic Fungi in model experiments. The Fungi were examined using the hair baiting method and the dilution method with incubation on a Wiegand medium supplemented with chloramphenicol (100 mg/L) and actidione (500 mg/L). The sludge liming considerably decreased the number of actidione-resistant Fungi propagules and eliminated many fungal species, including Pseudallescheria boydii. The influence of this process on hair-baited Fungi was that the liming eliminated keratinolytic and Keratinophilic Fungi at 37 o C. In the range of 23-33 o C, the liming considerably restricted the growth of keratinolytic Fungi, including Microsporum gypseum, but only slightly affected Keratinophilic Fungi, including Pseudallescheria boydii. The sludge liming decreases the risk posed by geophilic dermatophytes and other keratinolytic Fungi, as well as by Keratinophilic Fungi to humans and the environment. The process affected more keratinolytic Fungi than Keratinophilic ones.

Effect of sewage sludge alkalization and acidification on keratinolytic and Keratinophilic Fungi
Polish Journal of Environmental Studies, 2005Co-Authors: K. UlfigAbstract:This study aimed to determine the influence of sewage sludge alkalization and acidification on the qualitative and quantitative composition of keratinolytic and Keratinophilic Fungi in a model experiment. The sludge was alkalized to pH 9 with 0.5N NaOH, 0.5N KOH, 0.5N NH 4 OH or with 2% burnt lime mixed with powdered limestone (20g CaO + 5g CaCO 3 ), and acidified to pH 4 with 0.5N HCl, 0.5N HNO 3 or 0.5N H 2 SO 4 . The sludge with unmodified pH (6.5) served as control. The hair baiting method with four incubation temperatures (23, 29, 33, and 37°C) was used to examine Fungi. The sludge alkalization with KOH, NaOH or CaO+CaCO 3 increased the number of keratinolytic Fungi but decreased the number of Keratinophilic Fungi. The inhibition of the growth of keratinolytic Fungi was observed due to the sludge acidification with H 2 SO 4 or HCl. The sludge acidification with HNO 3 or HCl stimulated Keratinophilic Fungi to grow. Sludge acidification with HNO 3 eliminated keratinolytic Fungi, while acidification with H 2 SO 4 eliminated Keratinophilic Fungi. Results are discussed from ecological and epidemiological points of view.
