UTILIZATION OF SWEETWATER AS A COST-EFFECTIVE CARBON SOURCE FOR SOPHOROLIPIDS PRODUCTION BYStarmerella bombicola(ATCC 22214)

Abstract: Biosurfactants are microbially synthesized surfactants that are environmental friendly due to low toxicity. Sophorolipid is one of the simplest biosurfactants with well-defined structure produced by Starmerella bombicola(ATCC 22214) on glucose and vegetable oil as the carbon source. The raw material cost accounts for 10-30% of the overall cost. Glycerol is readily available from a commercial fat-splitting process as sweetwater at a very low cost. Sophorolipids was synthesized using glycerol and sweetwater as a… Show more

“…Here, we are reporting for the first time the use of sweetwater as a carbon source for PHA production. Sweetwater is considered to be a potential carbon feedstock, which can be used for biomaterial production (Wadekar et al, 2012;Azemi et al, 2016). Previously, sweetwater was used as carbon source for rhamnolipid production by Pseudomonas aeruginosa UMTKB-5 strain (Azemi et al, 2016).…”

“…Sweetwater is obtained during the process of sugar production by repeated carbonization and filtration of brown sugar, which is known as the residual syrup, whereby no crystalline sucrose can be obtained. The yield of sweetwater is approximately 4.0-4.5% per ton of cane sugar (Wadekar et al, 2012). The cane molasses is obtained from repeated crystallization process of raw sugar and the yield of cane molasses is approximately 3.0% per ton of cane (Parez, 1998).…”

“…1). В дальнейших исследованиях штаммы культивировали в течение 120 ч. Литературные данные свидетельствуют, что концентрация поверхностно-активных ве-ществ, образуемых различными продуцентами на техническом глицерине, как правило, не-высокая [9][10][11][12]16]. Так, штамм Bacillus subtilis LSFM-05 при культивировании на среде с 5 % технического глицерина синтезировал 1,36 г/л сурфактина [10] и такое же количество гомоло-гов фенгицина [9].…”

“…При выращивании Pseudomonas aeruginosa MSIC02 на среде с предвари-тельно гидролизованным (обработка серной кислотой) техническим глицерином (5 % по объ-ему) количество синтезируемых рамнолипидов составляло 1,27 г/л, а на среде, содержащей негидролизованный субстрат, было в несколько раз ниже [11]. Штамм Starmerella bombicola ATCC 22214 синтезировал до 6,6 г/л софоролипидов на среде, содержащей 15 % (по объему) технического глицерина и/или 10 % (по объему) подсолнечного масла [16]. Более высокие показатели (около 9 г/л гликолипидов) наблюдались при культивировании в течение 12 сут Ustilago maydis на среде с 50 г/л технического глицерина [12].…”

“…Отметим, что к недавнему времени в литературе было относительно не много сведений об образовании микробных ПАВ на смешанных субстратах, однако в по следнее время такой относительно простой путь интенсификации их синтеза привлекает все больше внимания [1,3,4,6,7,10,17,21].…”
