Characterization and sequencing analysis of pLP2.5-11 and pLP3.0-4 novel cryptic plasmids from WP72/27.

Unlabelled: We sequenced and described two cryptic plasmids from strain WP72/27, termed pLP2.5-11 (OP831909) and pLP3.0-4 (OP831910).

Conversion of golden oyster mushroom, to sugar syrup using enzymatic hydrolysis as a substrate for novel bacterial cellulose () fermentation.

Enzymatic hydrolysis of the golden oyster mushroom () generated a new bacterial cellulose (BC). The sugar syrup obtained from the hydrolysis of mushroom powder by commercial enzymes gave maximum total soluble solids (TSS) content at 8.83 ± 0.

Production and development of vinegar fermentation from broken Riceberry rice using raw starch-degrading enzyme hydrolysis.

Broken Riceberry rice was used as a substrate for sugar syrup production by the hydrolysis of raw starch-degrading enzyme as a low-temperature amylase (iKnowZyme LTAA, Thailand). Response surface methodology (RSM) with a central composite design (CCD) showed that an optimized substrate concentration of 250 g/L yielded 13°Brix of total soluble solid (TSS) content when incubated at 50 °C for 12 h. The major product from the broken Riceberry rice hydrolysis was glucose with lesser amounts of maltose and maltotriose.

Use of a starter culture of lactic acid bacteria in plaa-som, a Thai fermented fish.

Plaa-som is a Thai fermented fish prepared from freshwater fish and various ingredients. In this study, two strains of lactic acid bacteria (LAB) isolated from natural plaa-som fermentation were used as starter cultures: Lactobacillus plantarum IFRPD P15 and Lactobacillus reuteri IFRPD P17. These strains were used as a mixed starter culture for plaa-som using an air-drying method (laminar airflow) with sterilized rice grains as the filler.

Prevention of bacterial contamination using acetate-tolerant Schizosaccharomyces pombe during bioethanol production from molasses.

Bacterial contamination causes yield reduction during ethanol production from molasses. To prevent contamination, construction of a fermentation system using acetate-tolerant yeast under an acetate-containing condition was attempted. Schizosaccharomyces pombe was screened as an acetate-tolerant strain.
