Isolation and Characterization of a Promising Lignocellulolytic Enzyme Producer Pseudolagarobasidium acaciicola SL3-03 from Mangrove Soil in Thailand.

Lignocellulolytic enzymes isolation from mangrove-derived organisms has many industrial advantages due to their efficiency in dealing with extreme and challenging conditions, such as high temperatures and salt concentrations. This study aimed to isolate fungal enzyme producers from mangrove soil in Thailand to produce lignocellulolytic enzymes (carboxymethyl cellulase: CMCase, xylanase, and laccase) and to characterize these enzymes to support industrial applications. Forty-eight fungi were isolated from the mangrove samples, and their enzyme-producing capabilities were assessed using primary and secondary screening methods.

Isolation and Characterization of Xylanase from a Novel Strain, SP10.

Xylanase has been applied in various sectors, such as biomass conversion, paper, pulp, textiles, and pharmaceutical industries. This study aimed to isolate and screen potential xylanase-producing fungi from the soil of Suphan Buri Province, Thailand. Fifteen fungi were isolated, and their xylanase activities were tested by the qualitative method.

New Pyrrolobenzoxazine Sesquiterpenoid Derivatives from the Fungus Talaromyces trachyspermus.

Three new pyrrolobenzoxazine sesquiterpenoids, talatrachyoxazines A - C (1:  - 3: ), together with fourteen known compounds (4:  - 17: ), were isolated from the fungus EU23. Their structures were identified by spectroscopic evidence and mass spectrometry. The absolute configurations of 1:  - 3: were determined by NOESY data and comparison of their calculated and experimental electronic circular dichroism (ECD) spectra.

Efficacy of Chaetomium Species as Biological Control Agents against Phytophthora nicotianae Root Rot in Citrus.

Thailand is one of the largest citrus producers in Southeast Asia. Pathogenic infection by Phytophthora, however, has become one of major impediments to production. This study identified a pathogenic oomycete isolated from rotted roots of pomelo (Citrus maxima) in Thailand as Phytophthora nicotianae by the internal transcribed spacer ribosomal DNA sequence analysis.
