Coproduction of alkaline protease and xylanase from genetically modified Indonesian local CM1 using corncob as an inducing substrate.

The production of corn generates a substantial amount of agro-industrial waste, with corncob accounting for a significant portion of this waste. In this study, we focused on utilizing corncob as a carbon source and inducer to simultaneously produce two valuable industrial enzymes, protease, and xylanase, using a recombinant strain of CM1. Interestingly, xylan-rich corncob not only enhanced the xylanase activity but also induced protease activity of the modified CM1 strain.

Natural products as antivibrio agents: insight into the chemistry and biological activity.

Vibriosis causes serious problems and economic loss in aquaculture and human health. Investigating natural products as antivibrio agents has gained more attention to combat vibriosis. The present review highlights the chemical diversity of antivibrio isolated from bacteria, fungi, plants, and marine organisms.

Rhodophyta as Potential Sources of Photoprotectants, Antiphotoaging Compounds, and Hydrogels for Cosmeceutical Application.

Seaweeds are macroscopic, multicellular, eukaryotic and photosynthetic organisms, and are a source of chemical diversity with powerful biological activities for diversified industrial applications including cosmeceuticals. Red seaweeds (Rhodophyta) are good sources of Mycosporine-like amino acids (MAA) for photoprotectant and antiphotoaging compounds. In addition, Rhodophyta are also good sources for hydrogel compounds that are used widely in the food, pharmaceutical and cosmeceutical industries as gelling agents, moisturizers or for their antiphotoaging effects.

Bioinformatic analysis of the whole genome sequences of SARS-CoV-2 from Indonesia.

Background And Objectives: In first May 2020, Indonesia has been successfully submitted the first three full-length sequence of SARS-CoV-2 to GISAID database. Until September 10, 2020, Indonesia had submitted 54 WGS. In this study, we have analyzed and annotated SARS-CoV-2 mutations in spike protein and main proteases.

Phenotypic Variation of 46,XX Late Identified Congenital Adrenal Hyperplasia among Indonesians.

Objectives: To describe the phenotype variation in Indonesian 46,XX late-identified congenital adrenal hyperplasia (CAH) and the correlation between 17-hydroxyprogesterone (17-OHP) and genital virilization.

Methodology: Retrospective study of 39 cases with five salt-wasting (SW) and 34 simple virilizing (SV) types.

Results: The median age of the patients was 9.

Genetic features of red and green junglefowls and relationship with Indonesian native chickens Sumatera and Kedu Hitam.

Background: More than 2,500 breeds of chicken are reared throughout the world as a source of eggs or meat and as pets. The primary ancestor of the present domestic chicken is widely believed to be the red junglefowl, although genetic contributions from other junglefowls cannot be excluded entirely. The reference genome for chicken was obtained from a red junglefowl, the genetic purity of which has been debated.

Multiple maternal origins of Indonesian crowing chickens revealed by mitochondrial DNA analysis.

The utilization of Indonesian crowing chickens is increasing; as such, assessing their genetic structures is important to support the conservation of their genetic resources. This study analyzes the matrilineal evolution of Indonesian crowing chickens based on the mtDNA displacement loop D-loop region to clarify their phylogenetic relationships, possible maternal origin, and possible routes of chicken dispersal. The neighbor-joining tree reveals that the majority of Indonesian crowing chickens belong to haplogroups B, D, and E, but haplogroup D harbored most of them.

Constitutive high level expression of an endoxylanase gene from the newly isolated Bacillus subtilis AQ1 in Escherichia coli.

A xylanolytic bacterium was isolated from the sediment of an aquarium. Based on the 16S rDNA sequence as well as morphological and biochemical properties the isolate was identified and denoted as Bacillus subtilis (B. subtilis) AQ1 strain.
