Increasing interest in using food and agricultural wastes for low cost enzyme production continues in fermentation industry. Bacteria, especially Bacillus subtilis, are known to produce pectinases in synthetic media and media amended with agricultural wastes as a carbon source, whereas the potential of co-culturing Bacillus species to produce pectinases has not been fully studied yet. In this study, co-culture of B. subtilis and B. pumilus was optimized for solid load and pH to maximize pectinase production in submerged fermentation using apple pomace as the carbon source. Optimal pectinase activity was achieved as 11.25IU/mL with 15% apple pomace (solid load), pH 9.0, and 1/4 of culture ratio (B. subtilis/B. pumilus) at 30 degrees C after 24h of fermentation period according to the Box-Behnken response surface methodology. Thus, it was concluded that a twofold-increase in pectinase production was achieved by co-culturing of Bacillus spp. compared to our previous monoculture Bacillus study.


Pectinase production using apple pomace as carbon source by mixed culture fermentation
Kuvvet, Ceren; Çekmecelioğlu, Deniz; Department of Biotechnology (2016)
There is a growing interest in enzyme production from food and agricultural wastes to reduce the cost of production. Pectinases are one of the important group of enzymes used in fruit processing, alcoholic beverages, coffee and tea fermentation and textile industries. Pectinases can be produced by both solid state and submerged fermentation from various plant and microorganisms; however fungal microorganisms are the largest sources of bulk commercial enzymes and there are numerous studies on pectinase produ...
Bacterial cellulase production using grape pomace hydrolysate and synthetic sugar as sole carbon sources by shake-flask submerged fermentation
Kurt, Ayşe Sultan; Çekmecelioğlu, Deniz; Department of Food Engineering (2019)
Grape pomace is the major waste in the wine industry and it consists of high moisture content and residual sugars, which make it susceptible to rapid microbial spoilage. Thus, it needs to be disposed of with care to eliminate both environmental and health problems. The carbohydrate fraction of grape pomace is a fibrous material, and is an additional source of fermentable sugars to produce biofuel and hydrolytic enzymes. In this study, grape pomace hydrolysate was used for cellulase production with Bacillus ...
Enhancing the value of nitrogen from rapeseed meal for microbial oil production
Kiran, Esra Uckun; Salakkam, Apilak; Trzcinski, Antoine P.; Bakir, Ufuk; Webb, Colin (2012-05-10)
Rapeseed meal, a major byproduct of biodiesel production, has been used as a low-cost raw material for the production of a generic microbial feedstock through a consolidated bioconversion process. Various strategies were tested for the production of a novel fermentation medium, rich in free amino nitrogen (FAN): commercial enzymes (CEs) (2.7 mg g(-1) dry meal), liquid state fungal pre-treatment (LSF) using Aspergillus oryzae (4.6 mg g(-1)), liquid state fungal pre-treatment followed by fungal autolysis (LSF...
Extension of flower longevity in transgenic plants via antisense blockage of ethylene bıosynthesis
Deçani Yol, Betul; Öktem, Hüseyin Avni; Department of Biotechnology (2004)
Ethylene (C2H4) is a very simple molecule, a gas, and has numerous effects on the growth, development and storage life of many fruits, vegetables and ornamental crops. In higher plants, ethylene is produced from L-methionine in essentially all tissues and ACC Synthase and ACC Oxidase are the two key enzymes in the biosynthesis of ethylene. The objective of the present study was to transform tobacco (Nicotiana tabacum L. cv. Samsun) plant with partial sequence of torenia acc oxidase gene in antisense and sen...
Optimization of bioethanol production from kitchen waste
Uncu, Oya Nihan; Çekmecelioğlu, Deniz; Department of Food Engineering (2009)
Kitchen waste, which is collected in large amounts from cafeterias, restaurants, dining halls, food processing plants, and household kitchens, have become a valuable material for bioprocess engineering. Due to the high carbohydrate fraction, kitchen waste has great potential to be used as a potential substrate for ethanol production. Utilization of it as a raw material in ethanol fermentation would also contribute to reduction of costs. In the first part of this study, the effect of pretreatment method and ...
