“…Chitosan is an excellent chelating agent, well known for its biocontrol activity against pathogens (Goy et al, 2009;Franco and Peter, 2011;Berger et al, 2014) and as elicitor enhances stress tolerance, antioxidant activity, and production of osmoregulators in plants (Dar et al, 2015). As a coating material, chitosan can lower the formulation cost, making the final product multifunctional due to its biocontrol and plant strengthening activities.…”

Formulation of Microbial Inoculants by Encapsulation in Natural Polysaccharides: Focus on Beneficial Properties of Carrier Additives and Derivatives

In the last 10-15 years, the wide application of bioformulated plant beneficial microorganisms is accepted as an effective alternative of chemical agro-products. Two main problems can be distinguished in their production and application: (a) economical competiveness based on the overall upstream and downstream operational costs, and (b) development of commercial products with a high soil-plant colonization potential in controlled conditions but not able to effectively mobilize soil nutrients and/or combat plant pathogens in the field. To solve the above problems, microbe-based formulations produced by immobilization methods are gaining attention as they demonstrate a large number of advantages compared to other solid and liquid formulations. This mini-review summarizes the knowledge of additional compounds that form part of the bioformulations. The additives can exert economical, price-decreasing effects as bulking agents or direct effects improving microbial survival during storage and after introduction into soil with simultaneous beneficial effects on soil and plants. In some studies, combinations of additives are used with a complex impact, which improves the overall characteristics of the final products. Special attention is paid to polysaccharide carriers and their derivates, which play stimulatory role on plants but are less studied. The mini-review also focuses on the potential difficulty in evaluating the effects of complex bio-formulations.

“…In consideration of the amount of chitin produced annually all over the world, it is the most copious renewable natural resource after cellulosic substrate (Rinaudo 2006 ). Chitin has many unique functional properties including biocompatibility, biodegradability and non-toxicity for which it has been widely applied in the sectors of food, agriculture, medicine, and materials (Muzzarelli et al 2012 ; Franco and Peter 2011 ; Ling et al 2011 ). Now a days, chemical (Abdou et al 2008 ; Chandumpai et al 2004 ), enzymatic (Valdez-Pena et al 2010 ; Nakagawa et al 2011 ) and microbiological methods (Ghorbel-Bellaaj et al 2011 ; Jung et al 2007 ) have been applied to prepare chitin from shrimp shell powders (SSPs).…”

Production of chitin and bioactive materials from Black tiger shrimp (Penaeus monodon) shell waste by the treatment of bacterial protease cocktail

et al. 2014

The main objective of this study was to obtain chitin in pure form from a new crustacean waste material for industrial applications. Black tiger shrimp shell wastes are a rich source of protein and valuable bioactive carbohydrate polymers such as chitin. After removal of carotenoid, Black tiger shrimp shell wastes (BTSHWs) were treated with chemicals and protease enzyme to extract chitin. Box–Behnken response surface methodology was applied to optimize the deproteinization process to obtain chitin. At optimal pH (8.82), temperature (50.05 °C), agitation speed (100.98 rpm), enzyme substrate ratio of 1:8 (wv−1) and 72 h of incubation with Paenibacillus woosongensis TKB2 crude protease cocktail, 80 % deproteinization was found along with 77.28 % recovery of chitin. The valuable oligopeptides were determined by MALDI-TOF analysis and analysis of adequate amount of free amino acids in protein hydrolysate from BTSHW, indicating a high nutritional value used for food, feed or as a nitrogen source in growth medium for microorganisms. The chitin obtained was compared with the commercial chitin using scanning electron microscopy, Fourier transform infrared spectrometer, X-ray diffraction and 13C CP/MAS-NMR. Chitin obtained from crude protease treatment showed comparable physicochemical and structural properties to those of the commercial chitin. The carotenoid obtained after treatment can be used for medicinal purpose.Electronic supplementary materialThe online version of this article (doi:10.1007/s13205-014-0245-6) contains supplementary material, which is available to authorized users.

“…Traditional methods such as burning, land filling, and ocean dumping for chitinous waste removal becomes a serious environmental and economic issues (Suresh, 2012;Suresh and Chandrasekaran, 1998). Since this chitinous waste is a valuable renewable resource, several studies have been done to convert it into beneficial bioactive compounds to be applied in food, agriculture, medicine, and materials sectors (Muzzarelli et al, 2012;Franco and Peter 2011;Ling et al, 2011;Rashad et al, 2015) by the action of bacteria, particularly Streptomycetes.…”

This study aimed to explore the antimicrobial and chitinase activity produced by potent marine Streptomyces against Escherichia coli, MRSA and Aspergillus terreus. The powdered shrimp shell (SS) was used as a mono-component medium and tested for their effect on the production of active metabolites against three pathogens and chitinase activity. Shrimp shell was used as production media for optimizing fermentation conditions. The tested medium supported production of bioactive metabolite. Shrimp shell at 5.0 gl-1 exhibited significant antagonistic activity against pathogenic microorganisms and produced chitinase in cell-free supernatants at value of 0.56 U/ml/h, while the greatest chitinase activity value of 10.36 U/ml/h was achieved when grown on the shrimp waste as a mono-component medium (40 gl-1 shrimp waste in tap water).
