Screening of locally available organic materials as substrates for production of Pochonia chlamydosporia in Kenya

, 2019
Pochonia chlamydosporia is a nematophagous fungus with high potential for the biological control of root-knot nematodes (Meloidogyne spp.). The fungus is commonly produced in colonised rice substrate, but non-staple and more affordable substrates may ...

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Epitaxial growth of SiC on complex substrates [PDF]

, 2001
Epitaxial growth of SiC on complex substrates was carried out at substrate temperature from 1200 degreesC to 1400 degreesC. Three kinds of new complex substrates, c-plane sapphire, AlN/sapphire, and GaN/AlN/sapphire, were used in this study.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Co-existence of Methanogenesis and Sulfate Reduction with Common Substrates in Sulfate-Rich Estuarine Sediments

Frontiers in Microbiology, 2017
The competition between sulfate reducing bacteria and methanogens over common substrates has been proposed as a critical control for methane production.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Biochemical, Thermodynamic and Kinetic Characterization of Glucose Oxidase Purified from Pseudomonas and Actinomyces spp. from Natural Sources

Journal of Pure and Applied Microbiology, 2019
Glucose Oxidase (GOX) is naturally produced by several microorganisms. In this article, the enzymes isolated from Pseudomonas and Actinomyces species were studied for enzyme characteristics, activity, stability and kinetic parameters.
