Purification and evaluation of 2, 4-di-tert butylphenol (DTBP) as a biocontrol agent against phyto-pathogenic fungi.

A fungal strain, Marasmiellus sp (PUK64), isolated from the mangrove forests in Muthupet, Tamil Nadu, East coast of India, along with others were screened for the search of potent bioactive compounds. A phenolic compound, 2,4-di-tert-butylphenol (DTBP), was isolated from the most promising strain PUK64 and its chemical structure was ascertained. DTBP demonstrated remarkable antifungal activity against the phytopathogenic fungi Aspergillus oryzae, Curvularia lunata and Fusarium verticillioides.

A critical process variable-regulated, parameter-balancing auxostat, performed using disposed COVID-19 personal protective equipment-based substrate mixture, yields sustained and improved endoglucanase titers.

Fifty percent of the overall operational expenses of biorefineries are incurred during enzymatic-saccharification processes. Cellulases have a global-market value of $1621 USD. Dearth of conventional lignocelluloses have led to the exploration of their waste stream-based, unconventional sources.

A pilot-scale sustainable biorefinery, integrating mushroom cultivation and in-situ pretreatment-cum-saccharification for ethanol production.

Biomass pretreatment incurs 40% of the overall cost of biorefinery operations. The usage of mushroom cultivation as a pretreatment/delignification technique, and bio-ethanol production from spent mushroom substrates, after subsequent pretreatment, saccharification and fermentation processes, have been reported earlier. However, the present pilot-scale, entirely-organic demonstration is one of the very first biorefinery models, which efficiently consolidates: biomass pretreatment; in-situ cellulase production and saccharification; mushroom cultivation, thereby improving the overall operational economy.

Fungal diversity notes 1512-1610: taxonomic and phylogenetic contributions on genera and species of fungal taxa.

This article is the 14th in the Fungal Diversity Notes series, wherein we report 98 taxa distributed in two phyla, seven classes, 26 orders and 50 families which are described and illustrated. Taxa in this study were collected from Australia, Brazil, Burkina Faso, Chile, China, Cyprus, Egypt, France, French Guiana, India, Indonesia, Italy, Laos, Mexico, Russia, Sri Lanka, Thailand, and Vietnam. There are 59 new taxa, 39 new hosts and new geographical distributions with one new combination.

Phylogenetic Revision of Savoryellaceae and Evidence for Its Ranking as a Subclass.

Morphology, phylogeny, and molecular clock analyses were carried out on Savoryellaceae in order to understand the placements of taxa in this family. and formed a well-supported separate clade in the phylogeny of concatenated partial SSU, LSU, TEF, and RPB2 gene data. These two genera share similar morphological features, especially in their asexual morphs, indicating that they are congeneric.

Diversity and Distribution of Marine Fungi on Rhizophora spp. in Mangroves.

Rhizophora spp. occurring in mangrove habitats are excellent hosts for marine fungi. The morphological adaptations of this host plant provide suitable niche for the marine fungi.
