Self-directing optimization of parameters for extracellular chitinase production by Trichoderma harzianum in batch mode
P. Arthur Felse,Tapobrata Panda +1 more
TLDR
The self-directing optimization or the rotating simplex method of optimization was employed to determine the best suitable combination of parameters, pH (controlled), aeration rate and agitation rate for maximal production of chitinase by Trichoderma harzianum in batch culture.About:

Large scale production and increased shelf life of trichoderma harzianum inoculums in semi solid medium
TL;DR: An alternative semi solid medium has been developed for large scale fermentation of T. harizanum inoculums and showed more cell count and less chemical changes over time compared to solid or liquid media, two to three days after fermentation.

Production of Alcaligenes xylosoxydans EMS33 in a bench-scale fermenter.
TL;DR: Optimization of medium composition and pH for chitinase production by the Alcaligenes xylosoxydans mutant EMS33 was carried out in the present study and the optimization values of MgSO4 7H2O, Tween 20, chit in and pH were found to be 0.05, respectively.

Boosting extracellular dextransucrase production by Weissella confusa by combining a statistical and randomized mutational approach during upstream fermentation processing
Syeda Bushra Zafar,Afsheen Aman +1 more
TL;DR: In this article , a combinatorial approach that involves combining of classical mutagenesis and statistical optimization is attempted to scale-up productivity levels of dextransucrase, achieving an improvement of 8.5-fold.

The chitinase of Serratia marcescens.
Jaime Monreal,Elwyn T. Reese +1 more
TL;DR: Serratia marcescens was found to be the most active organism of 100 tested for the production of chitinase and Enterobacter liquefaciens produced nearly as much enzyme.
Degradation of plant pathogenic fungi by Trichoderma harzianum. Can J Microbiol
Yigal Elad,Ilan Chet,Yigal Henis +2 more
TL;DR: Isolates of T. harzianum were found to differ in the levels of hydrolytic enzymes produced when mycelium of S. rolfsii, Rhizoctonia solani, and Pythium aphanidermatum in soil was attacked, correlated with the ability of each of the Trichoderma isolates to control the respective soilborne pathogens.

Degradation of plant pathogenic fungi by trichoderma harzianum
Yigal Elad,Ilan Chet,Yigal Henis +2 more
TL;DR: Trichoderma harzianum excreted β-1, 3-glucanase and chitinase into the medium when grown on laminarin and Chitin, respectively, or on cell walls of the pathogen Sclerotium rolfsii as discussed by the authors.

Chitinases of fungi and plants: their involvement in morphogenesis and host‐parasite interaction
A.S. Sahai,M.S. Manocha +1 more
TL;DR: Chitinase induction in plants is not considered solely as an antifungal resistance mechanism, but there is some circumstantial evidence to suggest a morphogenetic role despite the apparent absence of the substrate in plant cells.

Bioconversion of shellfish chitin wastes: process conception and selection of microorganisms
Paul A. Carroad,Raymond A. Tom +1 more
TL;DR: Experimental results indicate that Serratia marcescens QMB1466 is suitable for use in the proposed bioconversion of shellfish chitin wastes to single-cell protein of value in animal or aquaculture feed formulations or to other products.
