Abstract Mangrove forest is one of the forest ecosystems that can be found in tidal areas. Mangrove forest have ecological, socio-economic benefits for organisms that live in the sea. One of the microorganism that live in mangrove forest is fungus. Therefore, this study aimed to isolate and identify phosphate solubilizing and cellulolytic fungi from mangrove soil. Soil samples were collected from a stands of Rhizophora stylosa in Lubuk Kertang Village, West Brandan District, Langkat Regency, North Sumatra. Soil samples were taken randomly with a dept of 0-20 cm. Isolation of phosphate solubilizing fungi was carried out using Pikovskaya medium and cellulolytic fungi using carboxyl methyl cellulose (CMC) medium. To determine the effectiveness of fungi qualitatively, the phosphate solubility and cellulolytic index were calculated. All isolates obtained were identified morphologically by observing colonies macroscopically and microscopically. This study obtained 12 isolates of phosphate solubilizing and 8 isolates of cellulolytic fungi. Phosphate solubility index ranging from 2.06-2.87 and cellulolytic index of 0.33-3.00. Morphological identifications showed that all isolates of phosphate solubilizing fungi belonged to the genus Aspergillus, while all isolates of cellulolytic fungi belonged to the genus Chaetomium.

Thermotolerant Fungi

Avian nests are a unique and sometimes extreme environment in which fungi occur. In this study, a correlation was recorded between the breeding biology and ecology of wetland birds and the biology and ecology of fungi in nests of wetland birds. The abundance of ecophysiologically diversified fungi, i.e. saprotrophs, cellulolytic fungi, and potentially zoo- and phytopathogenic fungi, was shown to be significantly higher in large nests, while species diversity (Shannon index) of fungi in nests with similar properties was not significant. The taxonomic structure (genus and species composition) and the spatial structure (frequency) of the nest mycobiota are mainly affected by nests’ specific physical and chemical properties which depend on the breeding and feeding preferences of the birds. In dry, highly sun-exposed nests of the Grey Heron (Ardea cinerea), a species that establishes breeding colonies high in the trees, mainly feeds on fish and has young who defecate into the nest, populations of xerophilic, alkali- and thermotolerant fungi, including keratinolytic fungi (Chrysosporium tropicum), developed. In the nests of the Mute Swan (Cygnus olor), a precocial species which constructs very large, relatively low-hygiene nests at the water's edge and which feeds on plant food, populations of hydrophilic and thermotolerant fungi, including highly cellulolytic fungi such as Chaetomium globosum, were detected. Nests of other small species of wetland birds, whose nests are also located on water but contain smaller amounts of animal-derived material, did not differ significantly mycologically and were colonised mainly by species such as Trichoderma viride and Penicillium purpurogenum, ubiquitous fungi with very high water and thermotolerant requirements.

Alkaliphilic cellulases-producer fungi were isolated from soil of limestone areas in Perlis. The potential strain was isolated by soil dilution plate method on enriched selective medium using CMC as substrate at different pH levels. Eleven isolates of different morphological colonies were screened using the hydrolysis capacity test by Gram’s iodine. Out of eleven colonies, five showed positive results as the hydrolysis zone formed. BK1 showed the highest hydrolysis capacity among all sample strains for every pH levels. Eventually, four strains were selected to be further explored as cellulolytic fungi for the production of alkaline cellulase in the future.
