“…Most of the species encountered in the present study were terrestrial forms, as was also observed by other workers (Rai et al 1969, venkatesan 1981, Miyoshi et al 1985, Mohamed Salique 1989. The reason might be attributed to large scale transport of fungal spores from the land through freshwater inflow in to mangrove ecosystem.…”

Abstract:We studied the microbial flora in decomposing mangrove leaves in relation to changes in nitrogen and tannin levels, and in penaeid prawn assemblages. Senescent leaves of two mangrove species (Rhizophora apiculata and Avicennia marina) kept in nylon bags, were separately immersed for 80 days in five tanks full of mangrove water. A known amount of decomposing leaves was collected every ten days from each tank for microorganism counts, total nitrogen and tannin measurement, and juvenile penaeid prawn counts. Five genera of total heterotrophic bacteria (THB), three species of azotobacters and 19 species of fungi were identified. The azotobacters showed a significant peak around 40-50 days after the beginning of of decomposition, similar to the trend for total nitrogen and for prawn assemblages. Rev. Biol. Trop. 55 (2): 393-400. Epub 2007 June, 29.Key words: Rhizophora, Avicennia, litter, microbes, decomposition, Azotobacter.Microorganisms play an important ecological role in decomposing organic matter and producing protein-rich detritus that serves as food to fishes especially in detritus-based marine ecosystems like mangroves (Dickinson and Pugh 1974, Steinke 2000, Mumby et al. 2004. Fungi are particularly important in the marine environment as decomposers of dead organic substrates (Kohlmeyer and Kohlmeyer 1979). The dead organic matter and the associated microorganisms form the base of the food webs of commercially important fishes and crustaceans. The undecomposed leaves are poor in nutrients, and they become nutritious due to the microbial enrichment process during decomposition (Odum 1971). The microbial decomposition of mangrove litter, has been extensively studied (Fell and Master 1973, Meyers 1974, Fell et al. 1975, Boonruang 1978, Cundell et al. 1979, Misra et al. 1984, Robertson 1988, Raghukumar et al. 1994, Rajendran and Kathiresan 1999a, 2000, Kathiresan and Bingham 2001, Rajendran and Kathiresan 2004 especially for the prevalence of fungi in decaying seedlings (Newell 1976). The microbial activity results in mineralization of detritus and a decrease in C/N ratio (Blum et al. 1988).Although microbes play an important role in the cycling of nutrients in the mangrove ecosystem, very little information is available about the types of microbes associated with decomposing leaves. These studies have not been extended to faunal assemblages associated with the decomposing leaves, especially for juvenile penaeid prawns which are usually abundant in mangrove waters (Rajendran 1997, Rajendran and Kathiresan 1999b. Hence, the present study was made on microbial load during decomposition of two mangrove species. mangrove forest at Pichavaram (11°27' N, 79°47' E) located in southeast coast of India and shade-dried. The leaves weighing at 500 g, without dissection, were packed in five nylon bags (35 x 35 cm, 2 mm mesh size) and submerged in five tanks (1.5 x 1.0 m), which were constructed separately for Rhizophora and Avicennia in the lower intertidal areas adjacent to the mangrove forest.

“…However, COLLINS and WILLOUCHBY (1962) found that the number of viable spores become lesser under 8-meter depth which exhibited low oxygen content. RAI et al (1969) have shown the occurrence of a large number of terrestrial fungi in the Indian mangrove swamps. HYDE and JONES (1988) isolated 47 species of marine fungi from the intertidal regions of Brillant and Anse Boileau mangrove stands (37 Ascomycotina, 1 Basidiomycotina and 9 Deuteromycotina).…”

Fungi inhabiting the aerial parts of two mangrove trees, Nypa fruticans, and Rhizophora apiculata, were studied from the central region of Thailand, utilizing morpho-molecular characteristics. Three different fungal taxa were isolated including Rhytidhysteron kirshnacephalus sp. nov., Lasiodiplodia citricola and Striatiguttula phoenicis. Sexual morphs are reported for these three taxa and the asexual morph of Striatiguttula phoenicis is identified based on molecular data. This is the first asexual morph report for the genus Striatiguttula as well as the family Striatiguttulaceae. The new isolate of Striatiguttula phoenicis differs slightly from other extant species in the genus in terms of measurements of ascomata, asci, ascospores, and thickness of peridium. Also, a pigmented hamathecium was observed in this species. The morphological results are congruent to the phylogenetic results of previous studies and support Striatiguttula phoenicis as a new host record from Nypa fruticans. Rhytidhysteron kirshnacephalus was collected from dead twigs of a standing Rhizophora apiculata in Cha-am and it has significant morphological and molecular differences to support its establishment as a novel taxon. Phylogenetically, Rhytidhysteron kirshnacephalus forms a sister clade to Rh. magnoliae, but has different ascomatal characters, including, smooth margins without striations and black pruina. Lasiodiplodia citricola is another species from Cha-am and a new record from Thai mangroves. Detailed descriptions of the isolates, along with their potential ecological roles, are provided. We have also provided the occurrence of fungi from the aerial parts of mangrove trees worldwide.
