Fine
bubble aeration diffuser for wastewater treatment tanks
D. Trifonov, N.
Tzonev, V. Vodenicharov, O. Tzarnorechki
Abstract. Fine bubble aeration diffusers are the
most
efficient means of transferring oxygen into process water and
wastewater. A
fine pore disc diffuser is developed with membrane of special HD-PE
material
and provides excellent chemical and thermal properties for the most
challenging
environments.
The
HD-PE diffuser element is with open pores throughout the solid plate
and
creates micro-bubbles, that results in increased oxygen transfer
efficiency.

Effects
of a biosurfactant-rhamnolipid
on bacterial growth and protein release
A. Sotirova,
D. Galabova, E.
Vasileva-Tonkova, E. Karpenko, A. Shulga
Abstract. The biosurfactant-rhamnolipid
PS from Pseudomonas sp.
S-17 contains a unique natural
complex of a biosurfactant and a biopolymer-alginate
with high surface and emulsifying
activities. The
biosurfactant is
a mixture of
two homologous
extracellular glycolipids.Effects
of a novel
biosurfactant-rhamnolipid PS
in batch cultures of Ps. aeruginosa, E.
coli and
B. subtilis on the growth,
extracellular protein
levels and cell
permeabilization were
studied. The biosurfactant
was shown to have a
neutral or detrimental effect on the growth
of Gram (+) strains and it
was dependent on the surfactant
concentration. The
biosurfactant PS
produced effects
well expressed
in vivo as
well as in
vitro on the B. subtilis 168 culture. The
growth of Gram (-) strains was not influenced by the
presence of
biosurfactant in the media.

Peculiarities of the research
organization in bioprocess engineering. Part 1. Objects of
investigation and specificity of experimental work
L. Nikolov
Abstract. Peculiarities of the
research organization
in the field
of Bioprocess Engineering are revealed. In the
Part 1. it
is made on
the basis of comparative
analysis of the objects of
R&D activity
and experiments
in Bioprocess Engineering
with those of other sciences, such as Chemistry,
Biology and Chemical Engineering.
The next parts of this study treat the implementation of the
Program-Target Method
and the System Approach to the organization activity, emphasizing on
its
specificity of each of the stages in the research
development. Some considerations about the improvement of R&D
activity organization
in the field
of Bioprocess Engineering are made.

Abstract: A hybrid
biosensor for catechol concentration
measurement is
investigated. There
is a cyclic
reaction for the substrate which
increases biosensor's
sensitivity. A
tissue from potato
plant
and mushroom is used
as an active
membrane and L-ascorbic acid is a non-measurable
substrate. An
oxygen
electrode is a
based transducer. For hybrid biosensors with cyclic enzyme-chemical reaction,
experimental transfer functions are obtained
and coefficient
of amplification
is calculated.

Spatial
modelling of the health status of the Chouprene
biosphere reserve forests
E.
Roumenina, V. Dimitrov
Abstract: The
paper deals with the problem
of influence of relief characterisitics
on health status of old-growth
spruce and beech forest formations
in Chouprene biosphere reserve. A modeling procedure
is developed based on 3D
and spatial analysis in a
geographic information
system. During
the modeling new
thematic layers
are generated and
thematic maps are composed. Quantitative
results are obtained about the presence of
a relation between the health
status of spruce and beech
formations and
relief characteristics.
Растителните биотехнологии през xxi век – спасение за човечеството
G. Kosturkova
Abstract: The Global population is estimated
to reach 8 billion people
by 2020 creating
a problem in meeting the
demands of food. Increasing of food production
on the basis
of expanding the cultivated agricultural areas
is limited. Hence,
increasing productivity
on the basis
of new technologies
is a possible
solution. Biotechnologies
have developed
rapidly passing
from the sphere
of science into the sphere
of industry. However, some moral and legal
issues have arisen. All this
problems are discussed
in the paper.
