(WATER & SOIL
CONDIATIONER)
Accumulation
of uneaten feed, excreta, dead plankton create a sludge on the
pond bottom and turbid water above. Digestion
of sludge
by indigenous microorganisms is slow and takes dissolve oxygen
away from the crop. In addition, there is a build up of ammonia,
nitrites
and other toxic inhibitory products. Therefore, to improve the
aquatic
environment there must be a reduction in accumulation of these
substances. It is well known fact that chemical and physical
methods are costly
and are temporarily beneficial. The reduction of sludge is best
possible by BIOAUGUMENTATION of the existing microorganisms through
regular addition of biologically active seed cultures such as PROBAC – BC…………………………..........
COMPOSITION & MODE
OF ACTION:…………………………………..
PROBAC –BC
contains special mixture of non pathogenic microbial cultures
viz., Bacillus subtilis, B. licheniformes,
B. polymyxa,
B. megaterium, B. pumilus, two strains of cellulolytic fungi
of the genus Aspergillus (A.oryzae and a. niger) which are
adapted to produce large amounts of waste degrading enzymes like
amylases,
proteases, lipases and cellulases. It contains bacteria that
oxidize
ammonia to form nitrites and nitrates. The cultures of probac-BC
enhance the natural nitrification cycle. Simultaneous with nitrification,
denitrification occurs, which converts harmful nitrates and ammonia
into harmless nitrogen gas, nitrous oxide and nitric oxide. This
process is carried out by the facultative denitrifying bacteria
in probacBC.

Advantages:
- Reduces
BOD and COD
- Works
efficiently in wide range of PH (3 - 9.5) and Salinity
(0-50)
- Reduces
sludge and maintains water quality
- Regulates
PH and stabilizes bloom
- No
tideous process such as brewing and aeration required
- Highly
concentrated and produces huge amounts of digestive enzymes
- Works
in aerobic and anaerobic condition
