For birth and death processes with finite state space, we consider stochastic processes induced by conditioning on hitting the right boundary point before hitting the left boundary point. We call the induced stochastic processes the conditional proce

Gene duplication is one of the major mechanisms of molecular evolution. Gene duplication enables copies of a gene to accumulate mutations through functional redundancy. If a gene encodes a specific protein that interacts with other proteins, RNA, or

Compensatory mutations are individually deleterious but appropriate combinations of mutants are harmless. For several models of compensatory molecular evolution, we consider the effects of back mutation. It is shown that the effects of back mutation

Recombinant cyclodextrin glycosyltransferase (CGTase) was obtained by cloning the PCR gene fragment from thermotolerant Paenibacillus sp. strain RB01 screened from hot spring area in Thailand and cloned into the Escherichia coli expression vector. Th

Endo-β-N-acetylglucosaminidases hydrolyze N,N´-diacetylchitobiose linkages of asparagine-linked oligosaccharides. They can also cleave the linkage with suitable agents having hydroxyl groups and transfer the released oligosaccharides to the agents.

Consider two sites under compensatory fitness interaction, such as a Watson-Crick base pair in an RNA helix or two interacting residues in a protein. A mutation at any one of these two sites may reduce the fitness of an individual. However, fitness m

A Cyclodextrin (CDs) producing bacteria was isolated from waste of starch factory in Thailand and identified as Bacillus circulans by biochemical characterization and Paenibacillus sp. by 16S rRNA. The Paenibacillus grew and produced cyclodextrin gly

Raw-starch-digesting alpha-amylase (Amyl III) was purified to an electrophoretically pure state from the extract of a koji culture of Aspergillus awamori KT-11 using wheat bran in the medium. The purified Amyl III digested not only soluble starch but

We consider a Wright-Fisher model whose population size is a finite Markov chain. We introduce a sequence of two-dimensional discrete time Markov chains whose components describe the coalescent process and the fluctuation of population size. For the

Loss of within-population genetic diversity by genetic drift is related to stocking. In order to reduce it, selective use of wild-born individuals for hatchery broodstock is proposed. Its effectiveness is evaluated by the analytical method and numeri
