Nutrient supplements in agriculture are crucial for plants
healthy growth and for production of high quality yield. The
scope of the present study was identifying and evaluating
systematically the possible influential role of the isolated S2
and S4 bacteria on degrading the industrial organic wastes such
as skins of chicken and skeleton of shrimp and hence, the
bacteria role in nutrient production. The possible impact of the
produced extracts of nutrient on vegetable plants early growth
and on enhancing soil fertility as compost was further studied.
The organic compounds, which originated from bacteria-waste
degradation, were used in irrigation of one-month grown crop
plants in non-fertile or in partially fertile soils. The
candidate cultivars were:
cucurbita pepo and Petroselinum hortense.
GC-MS analysis detected volatile organic compounds after wastes
degradation using bacteria, such as Nonanal,
6-Ethyl-2-methyldecane, Tridecane, 2, 3, 8-Trimethyldecane,
3-Dodecanamide, 1-cyclopentyl- Decane and Tetradecane. In
addition, some nitrogenous and amid compounds were found such as
Cyclo(leucyloprolyl), Cyclo(leucyloprolyl) isomers and
Hexadecanamide. Irrigated plants with extracts containing these
compounds along with S2 and S4 bacteria resulted in upregulation
of the overall seedling height, weight and dry matters compared
to irrigation using nutrient broth (NB) and mineral salt medium
extracts. Stepping forward to the environmental and human health
sustainability, we emphasize on: (1) substituting the NB
synthetic expensive carbon sources with the natural carbon rich
chicken and shrimp skins and, (2) using it for safer utilization
by cultivated plants and for plants growth improvement.
Key words: Bacteria, biofertilizer, chicken skin, GC-MS,
nutrient broth, shrimp skeleton.
