Sloughing spoilage of california ripe olives during processing is characterized by severe softening, skin rupture, and flesh sloughing. It was assumed that cellulolytic activity was responsible for skin rupture and sloughing of flesh, and so a deliberate search was made for cellulolytic bacteria from olives undergoing sloughing spoilage.
The lactic acid produced is effective at inhibiting the growth of other bacteria which can decompose and spoil the olives. While streptococcus and leuconostoc are the least acid-producing species, the members of the lactobacillus group are homofermentative and produce the highest amounts of acid.

We have isolated from plant surfaces several bacteria with the ability to catabolize indole-3-acetic acid (iaa). One of them, isolate 1290, was able to utilize iaa as a sole source of carbon, nitrogen, and energy. The strain was identified by its 16s rrna sequence as pseudomonas putida activity of the enzyme catechol 1,2-dioxygenase was induced during growth on iaa, suggesting that catechol.

Despite the fact that the degradation and detoxification of the olive mill wastes have been mostly investigated through the application of known bacterial and fungal species originated from other environmental sources, the biotechnological potential of indigenous microbiota should be further exploited in respect to olive mill waste bioremediation and inactivation of plant and human pathogens.
Olive oil industry, actually one of the main agricultural activities in the mediterranean basin countries, generates two main waste- water streams, the first one from the washing of the fruit (olives per ton of processed olives, washing wastewater, oww) and the second one from the extraction of the olive oil (olive mill wastewater, omw, a mixture of the proper olive-fruit.
Previous tests using a growth medium and olive mill wastewater (omww) have shown that it supplies carbon and electron donors suitable for sulphate reducing bacteria (srb). We assessed the co-treatment of acid mine drainage (amd) and omww using srb-enriched bioreactors and identified the most abundant bacterial populations present under optimized conditions.

Oribatid mites have similar ecological functions as collembola; they are agents of organic matter decomposition and consequently are important in nutrient recycling. They feed on dead and dying tissues and/or yeasts, bacteria, and algae (krantz 1978), and are part of the diet of some ant species (wilson 2005).
